Luggage Check Result
Airline Luggage Size Limits vary by carrier, but most follow similar standards for carry-on and checked baggage.
How airlines measure luggage:
Most airlines use the “linear inches” or “linear centimeters” method:
Linear Dimension = Length + Width + Height
Some airlines specify individual maximum dimensions instead.
Standard carry-on limits (most airlines):
- US domestic: 22 × 14 × 9 inches (56 × 36 × 23 cm) including handles and wheels
- International: 21.5 × 15.5 × 9 inches (55 × 40 × 23 cm)
- Budget airlines: may be smaller, check specific airline
- Weight limit: 15-22 lbs (7-10 kg) on many international airlines. US domestic airlines generally do not weigh carry-ons.
Standard checked bag limits:
- Linear dimension: 62 linear inches (158 cm) maximum
- Weight: 50 lbs (23 kg) for economy, 70 lbs (32 kg) for business/first class
- Overweight fee: $50-200 for bags exceeding the weight limit
- Oversize fee: $50-200 for bags exceeding the size limit
Airline-specific carry-on dimensions:
- United/Delta/American: 22 × 14 × 9 in (56 × 35 × 23 cm)
- Southwest: 24 × 16 × 10 in (61 × 41 × 25 cm) — most generous
- Ryanair: 15.7 × 9.8 × 7.9 in (40 × 25 × 20 cm) — personal item only unless you pay
- EasyJet: 17.7 × 13.8 × 7.9 in (45 × 36 × 20 cm) — small cabin bag
Tips:
- Measure your bag with handles and wheels extended — that counts toward the limit
- Soft-sided bags can sometimes be squeezed to fit, hard-sided cannot
- Always weigh your bag at home before heading to the airport
- Consider a luggage scale (they cost about $10-15 and save you overweight fees)
This calculator checks your bag against standard limits and tells you if it meets carry-on or checked requirements.
