The Ultimate Carry-On Luggage Size Guide

The easiest way to avoid a hassle at check-in is to double-check the airline carry-on size limits before you start packing (or better yet, before you buy your luggage).

I researched the carry-on and personal item size limits for 175 domestic and international airlines to compile the ultimate guide to carry-on luggage size limits. This is the most comprehensive list of carry-on size limits on the web.

The general guideline is that carry-ons need to be under 22 x 14 x 9 inches for domestic flights, or 21.7 x 15.7 x 9 for international flights. However, every airline sets its own luggage restrictions, and those restrictions vary quite widely.

That’s why it’s important to research the rules for the specific airlines you’re flying with. I wrote this guide to be a straightforward resource where you can easily find the size restrictions for different airlines.

What to Know About Carry-On Luggage Sizing

Carry-on luggage is a smaller piece of luggage that you can take with you on a plane. Because it has to fit in the overhead bin, carry-on luggage is smaller than checked luggage and must fit within specific size restrictions set by airlines.

A carry-on bag can be a suitcase, duffel bag, backpack, or even an instrument case, but no matter what it looks like, it has to fit within the size limits.

If you shop around for carry-on luggage, you’ll notice some suitcases marketed as “domestic carry-ons” and some marketed as “international carry-ons.” The difference here is all in the sizing.

For carry-on baggage on domestic flights within the United States, the typical size limit is around 22 x 14 x 9 inches for carry-on bags and 18 x 14 x 8 inches, but some US airlines have larger or smaller limits.

If you’re traveling internationally, you’ll want to pay a bit closer attention to the size of your carry-on. International airlines tend to be stricter. Standard carry-on sizes are usually around 21.7 x 15.7 x 9 inches, and personal items are most often limited to 15.7 x 11.8 x 3.9 inches.

When in doubt, I recommend getting a suitcase that’s sized to work for both US and international flights. That way your bag is future-proofed for any trips you may take.

For most people, a carry-on bag is large enough to pack for 3-5 days, but if you pack light, a carry-on can easily be enough for longer-term one-bag travel.

The majority of domestic and international airlines will let you bring one carry-on bag and one smaller personal item onboard without extra fees. However, some budget airlines charge you a fee for a carry-on.

What to Know About Personal Item Sizing

Personal Item Size

When you fly, you’ll usually be allowed to bring along one personal item alongside your carry-on luggage. Your personal item can be a smaller bag like a purse, briefcase, or small travel daypack that needs to fit under the seat in front of you.

Unlike carry-on bags, which stay in the overhead bin, personal items are designed to be kept within easy reach. Think of it as a place to keep essentials you need access to during the flight.

Because of that, personal item size limits are typically much smaller than carry-on limits. Within the US, most airlines limit personal items to 18 x 14 x 8 inches. Outside the US, personal item size limits are usually much smaller, and they vary widely. The most common international personal item size is 15.7 x 11.8 x 3.9 inches.

I’ve managed to pack for week-long trips with just a personal item before (when I was flying with an ultra-budget airline that charged for carry-ons), but it was a tight squeeze.

Keep in mind that each airline has different size restrictions for personal items, so it’s important to check the guidelines of the airline you’re flying with.

Why Is Choosing the Right Carry-On Size Important?

Right Carry-On Size

The main reason to make sure your carry-on luggage is the right size is to avoid any check-in surprises. Airlines have specific size restrictions for carry-on luggage, and if your bag exceeds these limits, you may be required to check it in at the gate.

This usually costs extra and can be a major hassle, especially if you packed items in your carry-on that you need access to in route.

In addition, choosing the right size for your carry-on is crucial for ensuring that your luggage fits perfectly in the overhead compartment. That’s the whole point of the restrictions in the first place!

Even if you make it onto the plane with a too-big bag, you don’t want to be the person blocking the aisle as you try to jam your suitcase into the overhead bin.

Just because you’ve used your carry-on before without any issues doesn’t guarantee it will work on every flight with every airline.

Carry-On Size Limits By Airline

Carry-On Size Limit by Airline

Most airlines have precise limits on how large your carry-on luggage can be. These limits vary from one airline to another, so it’s not as simple as buying a suitcase that’s advertised as carry-on compliant.

Just because a bag is marketed as a domestic carry-on doesn’t mean it absolutely fits on all US domestic flights, and just because it’s marketed as an international carry-on certainly doesn’t mean it will fit on any flight around the world.

The only way to be sure is to compare the dimensions of your luggage with the published size restrictions for the specific airline you’ll be flying with.

When measuring your carry-on luggage, remember that size limits include the handles, wheels, and any other component that sticks out from the main body of the suitcase. If you ignore those extra parts sticking out, you might find yourself with a bag that is too big and won’t be allowed on board.

What Can You Pack in Your Carry-On Bags?

Pack Carry-On Bag

Getting the right-sized suitcase or bag is just the first step in making sure you’re carry-on legal. You also need to know what you’re allowed to pack in your carry-on so you don’t get stopped at security for having a prohibited item.

Prohibited Items for Carry-On

The TSA has a long list of items that are not allowed in carry-on bags or on your person during a flight. This includes any weapons or anything that could be used as a weapon as well as flammable or toxic substances.

The list below includes common items that are not allowed in your carry-on, but it is by no means exhaustive. Always stay up-to-date with the latest TSA guidelines. When in doubt, it never hurts to take a moment to double check.

  • Firearms and ammunition
  • Knives and scissors
  • Liquids more than 3.4 oz per container
  • Sporting equipment (e.g., baseball bats, golf clubs, hockey sticks)
  • Self-defense items (e.g., pepper spray, tasers)
  • Tools (e.g., hammers, screwdrivers longer than 7 inches, wrenches)
  • Large quantities of liquids (e.g., beverages, shampoos, conditioners over 3.4 ounces or 100 milliliters)
  • Flammable items (e.g., lighter fluid, fireworks, flares)
  • Aerosol cans (except for limited amounts of personal care items)
  • Certain chemicals and toxic substances (e.g., bleach, paint thinner)

Batteries and Electronics

Your carry-on luggage is the best place for electronic devices and batteries. In fact, lithium batteries—which are found in most phones, laptops, and other portable devices—are not allowed in checked luggage. You have to carry them on.

Make sure your devices are packed securely in your bag where they won’t get damaged. You also want them to be easily accessible, since you usually have to pull out any device larger than a phone to go through security.

I recommend using a well-designed laptop backpack or bag to make sure your expensive laptop is both safe and within easy reach.

Restrictions on Liquids, Gels, and Aerosols

The TSA’s 3-1-1 rule is a key important guideline for packing liquids, gels, and aerosols in your carry-on bags. Don’t worry, it’s not too complicated!

Each passenger is allowed to bring a quart-sized plastic bag of liquids, and each container in the bag should be 3.4 ounces (100 milliliters) or less. So, pack your shampoos, conditioners, toothpaste, and lotions with these limits in mind.

Carry-On Luggage Size FAQs

Can 24-inch luggage be a carry-on?

A few airlines, like Frontier, allow 24-inch carry-on luggage, but most international airlines do not.

What is the TSA-approved carry-on size?

Carry-on size limits vary by airline. The most common limits are 22 x 14 x 9 inches for domestic flights, or 21.7 x 15.7 x 9 for international flights.

What if my carry-on is 1 inch too big?

Some airlines are pretty lenient on carry-on size, but even if your bag is only 1 inch too big, the airline can make you pay to check it.

What is the most strict carry-on size?

LATAM Airlines has one of the strictest carry-on size limits: 21.6 x 13.7 x 9 inches.

Will United allow a 24 inch carry-on?

No, United Airlines requires carry-ons to be under 22 x 14 x 9 inches.
