Luggage Size Calculator
Add up a bag's length, width and height (linear inches or cm) and check it against airline limits.
About the Luggage Size Calculator
Airlines limit checked bags by linear size, the sum of length + width + height, most often 62 in (158 cm). Carry-on rules usually give separate maximum dimensions as well (around 22 × 14 × 9 in in the US, or 55 × 40 × 20–23 cm in much of Europe and Asia), and weight limits apply too. Always check your airline and fare: budget carriers are stricter. Measure with wheels and handles included.
The formula
Linear size = length + width + height
Worked example
Example: Linear size = 49 in (124.5 cm)
- Inputs: Units: inches; Length: 24; Width: 15; Height (depth): 10; Airline limit (linear): 50.
- Formula: Linear size = length + width + height
- Result: Linear size = 49 in (124.5 cm)
