While there is no universal weight limit for checked bags, most airlines permit a checked bag of 62 linear inches (27” x 21” x 14”) with a maximum weight limit of 50 pounds.
The struggles of packing for a flight journey are real. Deciding what to pack in your carry-on and checked luggage without exceeding the airline’s weight limit can be a real pain, especially during the holiday season.
Scrambling around to make adjustments just before your trip to the airport, or even worse, at the airport check-in counter, is an absolute nightmare. It all comes down to the question, ‘How heavy can a checked bag be?’
The Quick Answer: Most airlines allow a checked bag with maximum dimensions of 27” x 21” x 14” (or a total of 62” linear size) with a maximum weight limit of 50 lbs.
Of course, checked bag weight limits vary based on the airline, your destination, and your flying class.

Checked luggage weight limit
Most airlines permit passengers to have one carry-on and one checked bag.
The standard weight limit on most airlines in the US is 50 lbs (23 kg) per checked bag. Spirit Airlines and Allegiant are some budget carriers that allow only 40 lbs.
Besides the weight limit, checked bags must measure 62 inches (158 cm).
It isn’t unusual to expect a higher allowance for some international airlines.
The permitted weight limits for checked bags and the number of checked bags you can take along depend on the following:
- The airline
- The destination
- The class you’re flying in
- Other exceptions (children/infants, US military personnel, etc.)
Exceptions
Most airlines waive checked bag fees for passengers flying First or Business Class, military personnel on active duty, and those with elite status with the airline.
While any checked bag exceeding the permissible weight limit will need you to pay the excess (overweight) fees, any bag weighing over 100 lbs will probably not fly. This is because even overweight bags have a weight allowance cap by airlines.
Whether you take your checked luggage free or with an excess baggage fee, the size limitations are 62 linear inches for each checked bag.
Useful tip
Keep a luggage scale handy to be sure of the weight of your checked bag
You can even keep one inside your suitcase and use it to weigh your bag while returning.
