Linear Inches Calculator
Enter suitcase dimensions to confirm whether your luggage meets airline checked or carry-on size requirements.
Most airlines allow 62 linear inches for checked bags.
Linear measurement: 50.0 in (127.0 cm)
Allowance usage: 80.6% of 62 in allowance
How to Use This Calculator
Measure your bag
Include wheels, handles, and exterior pockets. Use a tape measure for accuracy.
Enter each dimension
Input length (tallest dimension), width, and depth (front to back).
Compare with airline rules
Use the allowance field to check if you fall below common limits like 62" for checked baggage.
Formula
Linear Inches = Length + Width + Height
Linear Centimeters = Linear Inches × 2.54
% of Allowance = (Linear Inches ÷ Allowance) × 100
Example: 24" + 16" + 10" = 50 linear inches. Within a 62" checked baggage limit.
Travel Planning Tips
- Check regional airline rules—some limit checked bags to 60 linear inches.
- Carry-on limits vary (usually 45 linear inches). Measure before buying new luggage.
- Soft bags compress; hardshells may exceed limits once wheels are considered.
- Use the calculator for sports gear (golf bags, skis) to avoid oversize fees.

Enter inches and review the centimeter equivalent output for metric-based airlines.
How precise must measurements be?
Measure to the nearest 0.5 inch. When in doubt, round up and assume gate agents may remeasure.
