How to Choose the Right Luggage Size for Your Trip

Tired of overpacking into bulging suitcases or dishing out extra cash for overweight baggage fees at the airport? If so, you are far from alone. Travelers of all stripes have a difficult time choosing the proper size luggage when preparing to head out on a trip. This can lead to frustrating packing ordeals, unexpected costs, and avoidable hassles at the airport.

Selecting the right size luggage is an essential component of any travel plan, but one often overlooked by the average traveler. It is critical to matching the correct luggage size to the length of your trip, your destination, your airline, and your personal travel style. Opting for a too-large or too-small suitcase can result in expensive fees, travel inconveniences, or even running out of the things you actually need.

In this guide, you will discover the proper luggage sizes for any travel scenario. We provide advice on airline size and weight restrictions, along with common sense tactics for pairing your luggage with specific travel needs. You’ll also learn how the length of your trip influences the best luggage size, what different destinations call for, and how to sidestep the frequent sizing pitfalls that trap unsuspecting travelers in lines at airport check-in counters, racking up hundreds of dollars in extra fees every year.

Whether you are jetting off for a quick weekend trip or embarking on an extended excursion, this guide can help you buy the right luggage and avoid unnecessary stress. By the end of this post, you’ll know precisely what size luggage is suitable for your personal travel style and how to avoid those dreaded fees at the airport.

Measuring Luggage Size

Airline luggage measurements and terminology can get a little confusing for those not familiar with the lingo. To start with, most airlines size luggage by “linear inches”. The length, width, and depth of the bag are added together to arrive at this measurement. These linear inches determine if a bag is considered carry-on size or if it is a checked bag.

Size Guides for Carry-On Luggage

Carry-on luggage will typically have maximum linear dimensions of about 45 inches. This size can range from 22” x 14” x 9” for a small carry-on bag to 24” x 17” x 10” for a larger one. They generally hold about 2-4 days of clothing and supplies depending on how you pack. Having a carry-on bag can save you fees while also keeping your valuables within reach during a flight.

Medium Checked Baggage Dimensions

Medium checked bags usually stand between 24” and 26” tall and are most appropriate for one-week getaways. They provide much more room than a carry-on while still being light enough for most travelers to lift. This is the middle ground many travelers find when they want more space but not excessive space.

Maximum Dimensions for Large Checked Bags

Large checked bags can be anywhere from 28” to 32” in height. They are ideal for long vacations or when you need the additional space. Large bags hold the most but can be a challenge to lift and carry when heavy. They are also most prone to overweight surcharges if you are not careful with packing.

Measuring Your Luggage

The easiest way to measure your luggage is to find the height, width, and depth at their widest points and add those three measurements together. This is the linear inches measurement that airlines and retailers use to categorize bags.

Airline Luggage Size and Weight Requirements by Carrier

Airline baggage fees can either add or subtract significantly from your travel budget, and since various carriers have slightly different size and weight limits, it is important to be aware of these nuances if you want to avoid surprise fees at the airport.

Major Airlines in the US

Delta, American and United have similar requirements for carry-on luggage at 22” x 14” x 9”, but the checked bag allowance is less consistent. Delta’s checked luggage can weigh up to 62 linear inches, but some low-cost airlines only allow 50 linear inches.

Southwest Airlines offers two free checked bags weighing up to 50 pounds each, so it can be advantageous to opt for larger luggage if you tend to travel with this airline exclusively. If you’re going to switch between different carriers frequently, I recommend medium-sized luggage that can fit under the seat of most airlines.

Airlines from other countries

Air Emirates allows a maximum carry-on size of 55cm x 38cm x 23cm (about 21” x 15” x 9”) while British Airways also follows a similar scheme. This is marginally smaller than most US domestic airlines, so a carry-on approved by a US airline may not be accepted by these foreign carriers.

A common maximum weight for checked and carry-on luggage with international airlines is 8kg, which is about 17.6 pounds. For instance, Lufthansa and other European airlines enforce a strict 8kg weight limit, regardless of your luggage’s dimensions.

Budget airlines

Spirit Airlines, Frontier and Ryanair have the strictest size requirements and charge the highest fees for oversized luggage. Spirit’s maximum carry-on size is also smaller than the major US airlines. Their surcharges can add up to more than the ticket price if your luggage exceeds size and weight limits.

The reason for the higher fees with low-cost carriers is that they count on people oversizing their luggage at the airport. You’re much more likely to be caught with an oversized bag at budget airlines, since they make a significant profit from the fees and have less room to be lenient.

Matching the Trip Duration with the Size of the Luggage

Pick a luggage size based on how long you will be on your trip. There are always exceptions, but your travel duration should be the guiding principle when it comes to matching the luggage size to your packing list. While some people pack lightly, most will follow the general packing guidelines and bring what they need.

Weekend Trips (1-3 Days)

For trips shorter than four days, a carry-on suitcase will usually suffice for most people. This leaves room for two to three outfits, toiletries, and travel necessities. There will be no need for a checked-in bag on a short trip, and it will be more convenient to travel light, especially if you are looking to take a direct flight.

On a short trip, every hour counts, so the risk of losing a checked bag does not compare to the benefits of only traveling with a carry-on suitcase. Business travelers also love this packing approach, as it keeps them on the move and agile. By packing for one to three days, you can stick to multi-use pieces of clothing and accessories that can be mixed and matched. Additionally, only bring one backup pair of shoes.

Week-Long Vacations (4-7 Days)

Opt for a medium-size checked luggage for week-long trips. There is room for different types of outfits, shoes, and, in case your suitcase is not yet full when you return, a souvenir or two. In addition, a medium-size suitcase should give you space for weather variations and planned activities.
As a general rule, one full outfit for every day of your trip, plus one additional, and a coat, jacket, or other type of outerwear, is more than enough, but still, gives you some leeway. One medium suitcase usually leaves you with enough room to not be overly bulky.

Extended Travel (8+ Days)

Opt for large checked luggage for longer trips, but consider your specific situation. You might end up needing the same amount of clothing for two weeks in the same climate as you would for a single week in a more variable environment.

The more days you plan to travel, the more it makes sense to do laundry along the way instead of overpacking for a week or two at a time. People who stay longer tend to do laundry mid-trip as a matter of course. It allows them to use smaller bags than their shorter-stay counterparts while staying nimble and lowering their cost. Keep your accommodation type in mind: if it comes with laundry service, smaller suitcases are practical for long-term travel, but if you are venturing into more remote areas, you might need to pack enough for the full duration.

When adhering to these packing guidelines based on your trip duration, don’t forget to consider your destination and the activities you have planned. A one-week beach holiday requires far less bulk than a week on the slopes, despite both having an equal number of days.

Travel Style and Luggage Size

Your travel style influences luggage size more than any rule of thumb. Consider how you like to travel when choosing size for your needs and habits.

Minimalist Packing and Carry-on Only

Minimalists pack versatile basics and count on shopping as needed. This style allows maximum flexibility and lower cost, but needs more advanced planning. Minimalist travelers often use carry-on only, even for trips of a month or longer.

If you’re attracted to minimalist travel, focus on a high-quality capsule wardrobe that layers well and rolls up small. Select garments that work in multiple settings and climates.

Luxury Travel and Large Suitcases

Luxury travelers often need large luggage, because they’re more likely to pack formal outfits, multiple shoe/pair choices, and extra accessories. Luxury travelers are also more likely to shop on the road and need space for purchases.

Luxury travel is one of the few travel styles where large checked luggage makes sense because the extra cost and weight is worth the additional comfort and options.

Adventure and Outdoor Activities

Adventure travelers need extra space for specialized outdoor clothing, hiking boots, rain gear, and activity-specific equipment. Medium to large-sized luggage is often the right choice for this travel style, depending on the specific activities planned.

Choose a bag that can fit your bulkier gear comfortably, but remember your best carry-on luggage selection for electronics and valuables. Checked bags are ideal for gear that won’t be needed until later.

Business Travel

Business travelers have specific clothing and equipment needs. Wrinkle-resistant clothing, professional shoes, and electronics take up a lot of space, so while carry-on luggage is possible for most business trips, the bag needs smart packing and organization.

Look for bags that have dedicated laptop compartments and easy access pockets for travel documents and electronics.

Weight Considerations and Size Selection

Size isn’t the only consideration – weight is equally important for both airline compliance and travel comfort. After all, the empty weight of your luggage determines how much actual packing space you have, so weight is another important factor in the selection process.

The Impact of Empty Luggage Weight

Hard-shell luggage often weighs more than soft-sided bags but offers greater protection. A large hard-shell suitcase may weigh between 12 and 15 pounds empty, while a similar-sized soft-sided duffel might weigh between 8 and 10 pounds. That 5-pound difference can be the difference between fitting everything you want to bring and getting stuck at the 50-pound limit.

Before you make your purchase, look for the manufacturer’s specifications on the empty weight of the bag. This will allow you to calculate how much packing capacity you actually have.

Balancing the Load

Try to distribute the weight of your packed items evenly within your luggage. Heavier items like shoes and toiletries should be near the wheels, while you want to keep the center of gravity low to make the bag easier to maneuver.

If you carry on a heavy laptop and/or camera, you may want to consider lightening the load of your checked bags and keeping your valuables with you instead.

Lightweight Materials

Lighter-weight materials are now available that offer both durability and travel-wear resistance. Shop around for luggage that saves you weight without sacrificing the protection of your belongings.

A common debate among travelers is choosing between durable and lightweight luggage. The best option for you depends on your packing style and the types of trips you typically take. If you travel frequently and need more weight allowance for your belongings, then investing in lightweight luggage that will save you a few pounds on every trip may be the best solution for you.

The total weight of your luggage, including its contents, should never exceed the airline’s limits. Take a moment to figure out your total weight capacity. Simply subtract the empty weight of your luggage from the airline’s weight allowance to discover your real total weight allowance and pack accordingly.

Size Recommendations by Destination

The type of destination you are traveling to can significantly impact the size of luggage that’s most appropriate. Consider the nature of your trip when choosing a bag size to avoid overpacking and ensure you have room for destination-specific items.

Beach and Resort Destinations

Beach trips might require bulky items like towels and sunscreen, and even snorkeling gear. However, many resorts offer towels and basic beach equipment, so you might not need to pack as much.

A medium bag is usually a good size for beach destinations as you will need casual clothing that is often lightweight but bulky to pack. Make sure to leave some space for wet swimwear and any beach souvenirs.

Urban and Business Centers

Trips to cities or business destinations might require more formal clothing or business attire, which is less bulky but needs careful folding to avoid wrinkles. A carry-on suitcase can be ideal for short city trips, especially if you’re planning to stay in hotels with laundry services.

Think about the amount of walking you’ll be doing at your destination. If you’re traveling to a city with good public transport, you can probably get away with larger luggage. On the other hand, if you’ll be doing a lot of walking, smaller and more manageable luggage might be more convenient.

Adventure and Outdoor Destinations

Destinations involving skiing trips, hiking, or other outdoor activities often require specialized equipment that can be bulky and heavy. For these trips, large luggage usually makes sense, especially if you’re bringing your own equipment.

Check if there are options to rent equipment at your destination. It can be a lot easier to travel with if you plan to rent skis or camping gear at your location.

Cold Weather Destinations

Clothing for winter or cold-weather destinations takes up a lot more space than summer clothing. Coats, boots, and layering clothing will need bigger luggage, even for a short trip.

Pack your heaviest and bulkiest items to wear on the plane. Boots, heavy coats, and chunky sweaters can take up a lot of luggage space but can be worn during travel instead.

Don’t forget to plan for the return trip too. If you’re going to a shopping destination or a place known for unique purchases, you might want to bring larger luggage. If you don’t plan to buy much at your destination, smaller luggage will suffice.

Family Travel and Multiple Luggage Strategy

Family travel often involves luggage carried by multiple people, for the adults and any age-appropriate bags for children.

The ideal multiple-luggage strategy changes based on family size, the ages of your children, and the length of your trip.

Your children’s ages determine whether they have age-appropriate luggage or whether their belongings are packed by parents in parents’ bags or in larger family-shared bags. Even young “tote-wrangler” toddlers can often be responsible with their own small backpacks with a few age-appropriate toys, books, or entertainment items.

Kids under the age of 8 typically do not manage their own luggage well. In this case, parents may pack children’s clothing in one or both of their bags or larger shared family bags.

Kids ages 8–12 may be able to handle their own small carry-on or personal item bags and be responsible with a few of their own toys and entertainment items.

Teenagers, like other adults, are generally capable of handling their own medium-size luggage or larger. They may overpack, however, if they are not guided in how much to take and how to plan their outfits.

Planning strategy often comes down to individual bags or luggage for each person vs shared larger bags that are more efficient. Individual bags and personal items often work better when traveling with kids for longer trips, when family members have widely varying clothing sizes and packing needs, or when you may need to separate luggage or people in airports or in transit.

Shared bags and luggage with several people’s clothing may work well for shorter trips, especially if family members are close in size or clothing style or have similar packing preferences, or when you know most everyone will need access to everyone’s things.

Shared larger bags often weigh less overall than several smaller bags – one bag with a total weight of 30 lbs. is less than two 15 lb bags or three 10 lb bags.

A family travel luggage strategy often uses a mixture of sizes and bags. Carrying-on the adults’ electronics and all travel documents for every family member makes sense. Medium-size bags for most people’s clothing or travelers of all ages works well for longer trips. One or more larger shared bags often helps with bulky items or shared items like family toiletries.

A common family luggage mistake is to have every family member use their own bags but with no coordination or family-wide luggage strategy. This often leads to overpacking and all kinds of essential items being forgotten by each parent thinking someone else is bringing it.

Special Circumstances and Size Adaptations

Certain circumstances and special travel conditions require adaptations in your luggage size strategy. The following sections cover special circumstances that should influence your luggage size decision process.

Planning for special equipment, medical needs, or other unusual circumstances and conditions well before you leave your home base will help ensure a much smoother trip. Special circumstances often force you to adapt at the airport with little time or limited choices, which is never the ideal scenario.

Medical Equipment and Mobility Needs

Travel items like CPAP machines, wheelchairs, and other medical equipment often travel free as medical equipment but still count against your free luggage capacity. Find out your airline’s policies on medical equipment before your trip and consider that in your luggage size strategy.

Prescription medications should always be in carry-on luggage regardless of your carry-on and checked luggage choices. You should also bring extra medicine in case of travel delays.

Sports Equipment Accommodation

If you frequently travel with sports equipment like golf clubs, skis, surfboards, etc., factor these fees into your luggage strategy and overall travel costs. These special items often have special handling requirements and costs.

For example, if you travel with sports equipment, compare luggage that accommodates some of the sports equipment with the rest traveling separately with airlines’ sports equipment fees. In many cases, renting equipment when you arrive at your destination is cheaper than paying airline sports equipment fees.

If you travel often with sports equipment, consider luggage with some space to pack some of the equipment and allow some of the equipment to travel separately.

Business Equipment Transport

Special travel needs for business equipment like photography gear, laptops, or other job tools should be considered in the choice of luggage types and size.

In most cases, these equipment items travel better in carry-on luggage regardless of your overall checked luggage and carry-on luggage choices.

Think about weight distribution and spread out heavy business equipment between carry-on and checked luggage if possible to stay within weight limits.

Shopping and Souvenir Planning

Travelers headed to a shopping mecca or a city known for unique or locally made souvenirs often use a different luggage strategy. Some families or individuals pack an empty collapsible duffel bag or lightweight reusable shopping bag in one of their checked bags that they bring back filled with their purchases.

Other travelers use luggage with expandable capacity when they know they will likely buy things during the trip. Expandable luggage often zips shut at a smaller capacity but then has elastic or straps to expand the luggage for extra items. Planning this need during your initial luggage shopping is a better strategy than hoping that everything will fit in one of your bags on the return trip.

Find out your destination’s shipping options and costs too. It can sometimes be cheaper to mail some or all of your purchases home than oversized luggage or to buy an additional checked bag. Shipping is especially cheaper for some fragile or unusual items that airlines cannot handle.

Smart Sizing: Choosing Luggage Sizes Based on Costs

Determining what is the real cost of each luggage size will allow you to make financially savvy decisions about what type of luggage you want to invest in. Depending on how frequently you travel, the most affordable luggage size is not always the one you choose when you take into account both airline fees and your personal usage and long term value.

Airline Fees

With low cost airlines charging up to $100 for the first checked bag, the savings of a carry-on only approach can be a significant motivation to downsize. However, it can also lead to overstuffing and overspending if you have to abandon items that won’t fit in a carry-on or buy new items at your destination at a premium price.

It is important to tally up the true cost, including baggage fees and the opportunity cost of over-purchasing or under-performing luggage when making these decisions. For heavy or frequent travelers, it is often cheaper to purchase a higher quality and more expensive set of carry-on luggage rather than pay baggage fees.

Invest in Multiple Sizes

Investing in multiple luggage sizes based on the type of trip you are taking can also end up being a cheaper approach than standardizing on one particular size. A medium sized carry-on bag, medium suitcase and a large suitcase will cover business trips, vacations, and longer trips. Will pay off in the long term by allowing you to better plan each trip. Downsides to this approach are storage space and the up front financial commitment to more than one set of luggage. Tracking your luggage and travel patterns over the course of a year can help determine if this approach has financial merit for your personal situation.

Determining Your Cost Per Use

Luxury and high quality luggage tend to have a higher up-front cost, but may make more sense in the long term than an ultra-affordable set. In order to determine your cost per use it is necessary to consider your average number of trips per year over a multiple year period. A $300 bag used 20 times over a five-year period will have a cost per use of $15/trip.

In contrast, an $100 bag that has to be replaced after 8 uses has a cost of $12.50 per trip. The time, hassle, and inconvenience associated with luggage failure should be factored into the calculus as well. Avoidance of fees and more careful packing behavior with properly sized luggage will often amortize the cost of a more robust, well made luggage set within a few trips. A single $100 oversized bag fee can wipe out the difference between basic and luxury luggage prices.

Proper luggage sizing can save money not only on fees but by increasing the durability of the luggage you travel with and reducing shipping costs for replacements or new purchases. It is better to think of luggage as an investment in your travel life rather than simply an expense.

Choosing Your Ideal Luggage Size

In conclusion, when choosing your ideal luggage size, consider your travel habits, the airline restrictions, the nature of your travel destination, and your personal preferences. Balance these factors to select a size that is practical and compliant with airline policies while meeting your travel needs.

If you tend to travel for short periods, with a carry-on size or a small checked bag will likely suffice. However, if you frequently travel for long durations or to locations where packing more is necessary, a larger checked luggage may be more appropriate. Always verify the size and weight restrictions with your chosen airlines and check your travel destination’s specific luggage regulations.
Remember, the ideal luggage size is one that comfortably fits your belongings, complies with airline standards, and contributes to a seamless travel experience.

Key Takeaways on Picking the Ideal Luggage Size

1. Trip Duration: Longer trips often require larger luggage or multiple bags. Shorter trips may only need a carry-on or a small suitcase.
2. Airline Restrictions: Always check the size and weight limits of your chosen airlines to ensure your luggage complies.
