Best bag size for Ryanair, Wizz Air & easyJet
Flying Europe’s big three low-cost airlines? One free size covers all.
Fits the free bag allowance on all 3 reviewed airlines in this group. The tightest is Ryanair.
How to use this recommendation
Ryanair, Wizz Air and easyJet each include a small bag, but the three boxes use different proportions. This guide calculates one set of outside dimensions that can be used across all three without purchasing their larger overhead options.
The trade-off
The shared box cannot use the full easyJet allowance because Ryanair and Wizz Air bind different sides. Choosing a carrier-specific bag gives more capacity; choosing the intersection reduces repacking and fee risk on a mixed itinerary.
How we calculated it
For each airline we select its largest included allowance, normalise the three edges and calculate their common intersection. The result addresses dimensions only; Wizz Air’s weight ceiling and each carrier’s current fare conditions must still be checked.

What is the best free bag size for this group?+
A bag no larger than 40 × 30 × 20 cm (15.7 × 11.8 × 7.9 in), up to 10 kg fits the free bag allowance on all 3 airlines in this group — the limit is set by Ryanair.
Why not just buy the biggest bag?+
Because the strictest airline in the group wins. A bag that fits Ryanair fits everyone here; a larger one would be rejected or charged there. Buy for the tightest limit and you’re safe on all.
Should I leave a safety margin?+
Yes — measure with wheels and handles, and pick a bag a touch under the limit. A packed bag bulges, and low-cost airlines measure strictly at the gate.
