If you have ever dragged a huge suitcase to the airport and worried it might be too big, you are not alone. Airlines do not just care about weight. They also set a maximum size for checked baggage, and going over that limit can mean expensive oversize fees. If you understand the common limit and how to measure your suitcase the same way the airline does, you can avoid surprises at the counter.
Largest Luggage Size for Check In: Overview
Standard economy largest luggage size
- Up to 62 linear inches in total
- That means length plus width plus height equals 62 inches or less
- This is about 158 centimeters in total
Standard economy heaviest luggage weight
- Up to 50 pounds
- About 23 kilograms
If your suitcase is bigger than 62 linear inches or heavier than 50 pounds, the airline can charge oversize or overweight fees, or ask you to repack. Some premium cabins and specific routes allow more, but 62 linear inches and 50 pounds is the most common baseline for regular checked baggage.
Largest Luggage Size for Check In: Calculating Your Measurements
What does linear inches mean? It does not mean that any single side of your suitcase must be under 62 inches. Instead, it is the sum of all three sides.
Luggage size calculations
- Measure the length of the bag from end to end
- Measure the width side to side
- Measure the height from the floor to the top when the bag stands upright
- Add the three numbers together
- For example: 28 x 18 x 10 = 56, which is under 62.
Largest Luggage Size for Check In: Maxiumum Size
Maximum luggage size
- Maximum of 62 linear inches total
- Around 158 centimeters
Common luggage size
- Many large checked suitcases marketed as 28 to 29 inch cases
- Some extra large bags marketed as 30 inch cases might still fit, but you need to measure because shape and depth matter
What matters is not the advertised height of the suitcase, but the sum of all three sides including wheels. A tall but narrow suitcase might be within the limit, while a shorter but very deep suitcase with big wheels could go over.

Largest Luggage Size for Check In: Domestic vs. International Flights
Domestic flights luggage size
- The 62 inch and 50 pound rules are a typical standard for many full service airlines in economy
- Some basic economy fares may not include any free checked bag at all even though the size limit for paid bags is still 62 inches
International flights luggage size
- Many long haul routes still use 62 linear inches as the maximum for each checked bag
- Some routes use a piece system for example two bags up to 50 pounds each
- Some routes use a weight based system where the total checked baggage allowance is a certain number of kilograms without a fixed number of bags
Budget airlines and some regional carriers can have different rules altogether. For example, they might allow only one smaller checked bag or charge by weight and piece together.
Largest Luggage Size for Check In: Oversized Luggage
Oversized luggage procedure
- At check in the agent measures or eyeballs the bag
- If it clearly exceeds 62 linear inches or a published limit, it can be tagged as oversize
- You may be charged an oversize fee which can be significant, sometimes as much as or more than the base fare on some airlines
- In extreme cases very oversized or odd shaped items might need to go as special baggage or cargo and may not be accepted on every flight
If your bag is just slightly over the limit, things may depend on the airline, airport, and staff on duty that day. You should treat the limit as real, not just a suggestion, to avoid arguments or surprise costs.
Largest Luggage Size for Check In: Measuring Your Suitcase
Pack your luggage fully
- Pack the suitcase as you plan to travel
- Close all zippers including expansion if you will use it
Measure each side of your luggage
- Use a tape measure in inches
- Measure length from top to bottom of the longest side
- Measure width across the front from one side to the other
- Measure depth from front to back including any bulging pockets
Add your luggage measurements
- Write down the three numbers
- Add them to get the total measurement
If the number is over 62, the suitcase is technically oversize for many airlines. If it is under 62, you are likely to be within the standard limit.
