Standard airline limits for checked bags
The largest luggage size most airlines allow as a checked bag is 62 inches when you add the length, width, and height together. This is the standard set by most major carriers including American, Delta, United, Southwest, and JetBlue. A typical large suitcase that meets this limit measures about 28 inches tall, 20 inches wide, and 14 inches deep.
Weight matters as much as size. Most airlines cap checked bags at 50 pounds. If your luggage is within the 62-inch limit but weighs more than 50 pounds, you will pay an overweight fee—usually $100 or more for domestic flights. Some airlines charge by the pound once you exceed the limit, so a 60-pound bag might cost you $200 extra.
International flights sometimes have different rules. Airlines flying to Europe, Asia, or other regions may allow two checked bags instead of one, but each bag still cannot exceed 62 inches and 50 pounds. Always check your specific airline's website before packing, because budget carriers like Spirit and Frontier have stricter limits and charge for the first checked bag itself.
Key Takeaways
- The standard maximum checked luggage size is 62 inches (length plus width plus height), which fits a typical 28-inch rolling suitcase.
- Weight limits are usually 50 pounds per bag on domestic flights, and exceeding this triggers overweight fees starting around $100.
- Budget airlines and international carriers may have different size and weight rules, so you must verify with your airline before traveling.
- Carry-on bags have smaller limits—usually 22 by 14 by 9 inches—and do not count toward your checked luggage allowance.
- Oversized items like sports equipment or musical instruments may require special handling and additional fees even if they fit the standard dimensions.
Carry-on luggage is smaller than checked bags
Your carry-on bag—the one you take into the cabin—has a much tighter limit. Most airlines allow carry-on bags measuring no more than 22 inches tall, 14 inches wide, and 9 inches deep. This is roughly the size of a backpack or a small rolling bag that fits in the overhead bin.
Carry-on bags do not have a weight limit on most airlines, but they must fit in the overhead compartment or under the seat in front of you. If your bag is too large or heavy to lift into the bin yourself, a flight attendant may gate-check it—meaning it goes into the cargo hold anyway, and you lose the convenience of having it with you during the flight.
Some airlines are stricter about carry-on size than others. Southwest and JetBlue are generally lenient, while Spirit and Frontier measure bags at the gate and will charge you if yours is oversized. If you are flying a budget carrier, bring a bag you know fits the dimensions rather than guessing.
Oversized items need special handling
If you are traveling with something larger than a standard suitcase—a golf bag, a cello, a bicycle, or a surfboard—it counts as oversized baggage and requires special arrangements. You cannot straightforward check it as a regular bag. Most airlines charge $100 to $200 extra for oversized items, and some require you to call ahead to reserve space.
Sports equipment like skis, snowboards, and fishing rods often fall into this category. Airlines treat them differently depending on what they are: some allow one pair of skis free, while others charge for any sports gear. Musical instruments may be allowed in the cabin if they fit the carry-on limit, but large instruments like harps or grand pianos need advance notice and may require you to buy a seat for them.
If you are shipping something instead of traveling with it, that is often cheaper than paying oversized baggage fees. For a cello or a large piece of equipment, a specialized shipping service may cost less than $200 and removes the risk of damage during handling.
How to measure your luggage correctly
Measure your bag with a soft measuring tape, not a ruler, because luggage is flexible. Measure from the furthest point on each side: the top of the handle to the bottom of the wheels for height, the widest part of the bag for width, and the deepest part for depth. Round up to the nearest inch.
The 62-inch limit includes wheels, handles, and any pockets that stick out. If your bag has expandable sides, measure it in the expanded position if you plan to use that feature. Many travelers make the mistake of measuring a bag that is not fully packed, then finding it exceeds the limit once they fill it.
Write down your bag's dimensions and keep them in your phone. When you book a flight or check your airline's baggage policy, you can compare your actual measurements against the rules instead of relying on what the luggage tag says.
Luggage that exceeds airline limits
If your bag is larger than 62 inches or weighs more than 50 pounds, you have a few options. The first is to remove items and pack them in a second checked bag if your ticket allows it. Most domestic flights include one free checked bag; a second bag usually costs $35 to $50.
The second option is to ship items ahead of yourself. Services like UPS, FedEx, and USPS can deliver a box to your destination before you arrive. This works well if you are traveling for a week or longer and do not need the items when ready. For a cross-country shipment, expect to pay $50 to $150 depending on weight and distance.
The third option is to pay the oversized baggage fee. If your bag is only slightly over the limit and you are not traveling frequently, paying $100 to $200 once might be simpler than buying new luggage or shipping. But if you travel often, investing in a bag that fits the standard dimensions will save money over time.
Luggage size rules for different airlines
| Airline | Checked Bag Limit | Weight Limit | Carry-On Limit |
|---|---|---|---|
| American, Delta, United, JetBlue | 62 inches | 50 pounds | 22 × 14 × 9 inches |
| Southwest | 62 inches | 50 pounds | 24 × 16 × 10 inches |
| Spirit, Frontier | 62 inches | 40 pounds | 22 × 14 × 9 inches |
| Alaska Airlines | 62 inches | 50 pounds | 22 × 14 × 9 inches |
Budget airlines like Spirit and Frontier charge for the first checked bag itself—usually $35 to $45—so you are paying more from the start. They also have stricter weight limits at 40 pounds instead of 50. If you fly budget carriers often, a lighter bag and packing strategy will save you money.
International airlines vary widely. Some allow larger bags or multiple checked bags. Always visit your airline's baggage page before booking, because policies change and vary by route. A flight from New York to London may have different rules than a flight from New York to Mexico City on the same airline.
Frequently Asked Questions
Can I check a bag that is 63 inches if it is only 1 inch over?
Most airlines will not accept it. They measure at check-in, and bags over the limit are either rejected or charged as oversized. Some airlines are stricter than others, but you should not count on getting away with 1 inch over. If your bag is close to the limit, measure it carefully and consider removing items.
Do soft-sided bags get measured differently than hard-sided ones?
No. Both are measured the same way, but soft-sided bags are easier to squeeze into tight spaces. If your soft bag is slightly over the limit, you might be able to compress it enough to fit in the overhead bin as a carry-on, though this is not may provide and depends on the flight attendant's judgment.
What happens if my bag is overweight but under the size limit?
You will pay an overweight fee, usually $100 for the first 10 pounds over 50 pounds. Some airlines charge per pound after that. The size limit and weight limit are separate rules, so your bag can pass one and fail the other.
Are personal items like backpacks and purses included in luggage limits?
No. A personal item—a small backpack, purse, or laptop bag—is free and separate from your carry-on bag. You can bring both a personal item and a carry-on bag on most flights. Personal items have no official size limit, but they must fit under the seat in front of you.
Can I buy a larger suitcase and just pay the oversized fee every time?
You can, but it is expensive. If you fly twice a year and pay $150 in oversized fees each time, that is $300 per year. A new 62-inch compliant suitcase costs $100 to $300 and lasts for years, so it pays for itself quickly if you travel regularly.
