Do wheels and handles count in carry-on size?
Yes. Airlines measure the outside of the bag including wheels, handles and anything in the pockets, and the gate sizer is built to those numbers. Measure your bag packed.
What's the difference between a carry-on and a personal item?
The carry-on (cabin bag) goes in the overhead bin and is usually around 55 × 40 × 20 cm. The personal item goes under the seat in front of you and is smaller, often 40 × 30 × 15 to 20 cm. Budget airlines usually include only the personal item.
What happens if my bag doesn't fit the sizer?
It goes in the hold. On budget airlines like Ryanair, easyJet and Wizz Air that comes with a gate fee, often €45 to €70, which is more than adding a bag when you book.
My trip has connecting flights. Which limit applies?
Every flight checks its own limit, so pack to the smallest one. Add your connecting flights in the checker above and GateSizer shows the tightest size and weight across the whole trip.
