Standard checked luggage dimensions across major airlines
Most U.S. airlines allow one checked bag up to 62 inches when you add length, width, and height together. That translates to roughly 28 inches long, 17 inches wide, and 17 inches deep — the size of a standard rolling suitcase. Weight limits are usually 50 pounds for the first checked bag, though some airlines charge extra if you go over.
The exact numbers vary by carrier. American, Delta, Southwest, and United all use the 62-inch rule and 50-pound limit for at least one free checked bag. Alaska Airlines, JetBlue, and Spirit have the same dimensions but may charge for checked bags depending on your ticket type. International carriers often stick to the same 62-inch standard, though some European and Asian airlines use slightly different thresholds — usually between 50 and 70 inches.
If your bag is larger than 62 inches or weighs more than 50 pounds, the airline will charge an oversized or overweight fee, typically $75 to $150 per bag. Some airlines refuse to check bags over 80 inches or 70 pounds regardless of fee.
Key Takeaways
- Standard checked luggage is 62 inches total (length plus width plus height) and 50 pounds maximum on most U.S. airlines.
- A typical rolling suitcase measuring 28 by 17 by 17 inches fits within these limits and is what most travelers use.
- Oversized or overweight bags trigger fees of $75 to $150, and some airlines refuse to check bags over 80 inches or 70 pounds.
- Budget airlines like Spirit and Frontier may charge for your first checked bag unless you have a higher ticket class.
- International flights often follow the same 62-inch rule, but always check your specific airline before packing.
How to measure your luggage correctly
Measure the length, width, and height of your closed suitcase at its widest points, including wheels and handles. Use a soft measuring tape or a ruler and add all three numbers. If your bag is 27 inches long, 16 inches wide, and 16 inches deep, that is 59 inches total — within the limit. If it is 30 by 18 by 18, that is 66 inches and will trigger an oversized fee.
Weigh your packed bag on a bathroom scale or a scale at a shipping store. Most airlines have scales at the check-in counter, but you will know before you arrive whether you are close to the limit. If you are between 48 and 50 pounds, you have little room to add anything else.
What happens if your bag is too large or too heavy
If your bag exceeds 62 inches or 50 pounds, the airline will charge you at check-in. The fee is usually $75 for the first overage and $150 for a second checked bag or a bag that is significantly oversized. You can pay and check the bag, or you can repack it on the spot if you have time and a place to do so.
Some airlines, including Spirit and Frontier, charge for checked bags regardless of size if you have a basic economy ticket. Others, like Southwest, include two free checked bags for all passengers. Read your airline's baggage policy before you book, because the fee structure varies widely.
Soft-sided versus hard-sided luggage and size
Hard-sided suitcases (polycarbonate or ABS plastic) hold their shape and are easier to measure accurately. Soft-sided bags (fabric or nylon) can compress slightly, which sometimes lets you squeeze in an extra inch or two, but airlines measure them in their normal state. Do not rely on compression to get a bag under the limit.
Hard-sided bags protect contents better during handling and are less likely to tear, but they are heavier than soft-sided options. If you are close to the 50-pound weight limit, a lightweight soft-sided bag may give you a few extra pounds of packing room. Either way, the 62-inch dimension rule applies equally.
Carry-on versus checked luggage size
Carry-on bags are much smaller than checked bags. Most airlines limit carry-on to 22 by 14 by 9 inches and require it to fit in the overhead bin or under the seat in front of you. That is roughly 45 inches total, compared to 62 inches for checked luggage.
If you want to avoid checked bag fees or the wait at baggage claim, pack light enough to use only a carry-on. Many travelers use a small rolling bag (22 by 14 by 9) plus a personal item like a backpack or purse. If you need more space, you have to check a bag and accept the size and weight limits that come with it.
Second and third checked bags
Most airlines charge $35 to $50 for a second checked bag and $100 to $200 for a third. Each bag must still meet the 62-inch and 50-pound limits. If you are traveling with a family or moving, multiple bags add up quickly — a family of four checking two bags each could pay $140 to $200 in baggage fees alone.
Some airlines, like Southwest, include two free checked bags for all passengers, which makes them cheaper for families or people who pack a lot. Others, like United and Delta, charge for the second bag unless you have elite frequent flyer status or a premium ticket class. Check your airline's policy before you pack multiple bags.
Special items and size exceptions
Sports equipment like skis, golf clubs, and surfboards often count as checked bags and may have separate size and weight rules. Musical instruments, car seats, and strollers are sometimes exempt from baggage fees but still need to fit within airline dimensions or be checked separately. Call your airline before you travel if you are bringing anything unusual.
Fragile items should be packed in hard-sided luggage or a protective case. Soft-sided bags offer less protection during the baggage handling process, and airlines are not responsible for damage to items inside checked luggage unless the damage is caused by airline negligence.
Frequently Asked Questions
Can I check a bag that is 65 inches if I pay the fee?
Yes. Most airlines charge $75 to $150 for oversized bags and will check them as long as they are under 80 inches. Some airlines have a hard limit at 80 inches and will refuse to check anything larger, so confirm with your carrier before you pack.
Do wheels and handles count toward the 62-inch measurement?
Yes. Measure your closed suitcase at its widest points, including wheels, handles, and any protruding parts. This is how airlines measure, and it is how you should measure at home to avoid surprises at check-in.
What if my bag weighs 52 pounds?
You will pay an overweight fee, usually $75 to $100. Remove 2 to 3 pounds of items and repack, or pay the fee. Some airlines allow you to move items to a carry-on or a second checked bag if you have time at the counter.
Are checked bag sizes the same on international flights?
Most international airlines use the same 62-inch and 50-pound limits, but some European and Asian carriers allow smaller bags or have different rules. Check your specific airline's website before you book, because policies vary by region and carrier.
Do budget airlines have smaller checked bag limits?
No. Spirit, Frontier, and other budget carriers use the same 62-inch standard as major airlines, but they charge for checked bags on basic economy tickets. The size limit is the same; the fee structure is different.
