What this size is designed for

At 45 × 36 × 20 cm, this is a relatively generous free under-seat allowance associated with easyJet. The broad 36 cm face works well for laptop bags and structured backpacks, while the 20 cm depth keeps the item low enough for the space beneath the seat.

Best use

Use this size when most flights are on easyJet and you want the largest free bag the fare permits. Around 32 litres of theoretical box volume is available, although real capacity is lower once padding, rounded corners and internal dividers are taken into account.

Main trade-off

A bag that uses the full easyJet allowance will usually be too large for the free personal-item rules of Ryanair, Wizz Air and several other low-cost carriers. For mixed-airline travel, the strictest carrier should set the purchase size rather than the most generous one.

Measure before flying

The depth is most likely to grow after packing. Measure across the fullest point with every outer pocket loaded, and include handles that do not fold completely flat. A flexible bag may compress into the sizer, but that should be treated as a small safety margin rather than the plan.
