Calculates the “linear inches” figure airlines and shipping carriers use to size luggage and packages — a simple sum, not a volume.
How it works
The length, width, and height are added together directly.
What this does not include
This does not include specific airline or carrier size limits — those vary by company, so check the specific carrier’s published policy against your total.
How to use this calculator
- Enter the length, width, and height of your luggage or package.
Frequently asked questions
Why is linear inches a sum instead of a volume calculation?
Because airlines and carriers use it as a simplified proxy for overall bulkiness, not an exact measure of space occupied — a sum is easier to check quickly than a volume formula.
What’s a typical linear inches limit for checked luggage?
Many airlines cap checked bags around 62 linear inches, though this varies by carrier and fare class — always check your specific airline’s policy.
Does this apply to carry-on luggage too?
Carry-on limits are usually expressed as individual dimension limits rather than a linear inches total, so check your carrier’s specific carry-on policy separately.
