A 40L backpack approaches EasyJet's large cabin bag limit of 56 × 45 × 25 cm. Most soft-sided 40L bags fit within these dimensions when packed carefully. However, overpacked, structured, or rigid-frame bags may exceed the limit — particularly in depth — and risk being gate-checked. Large cabin bag access requires a paid upgrade or bundle. Without it, only a small cabin bag (45 × 36 × 20 cm) is allowed free, and a 40L bag is far too large for that.
Check if this will actually fit your trip →Your result depends on what you pack, not just the bag size.
Based on real clothing volumes and packing behavior
| Small cabin bag (free) | 45 × 36 × 20 cm — must fit under the seat |
| Large cabin bag (paid) | 56 × 45 × 25 cm (22 × 17.7 × 9.8 in) — requires paid upgrade or eligible fare |
| Weight limit | No strict weight limit — must be self-liftable into overhead bin |
| Enforcement | Bags measured at the gate — oversized large cabin bags may be gate-checked |
| Fit at 40L | Near the large cabin bag limit — soft-sided bags fit; overpacked or rigid bags may not |
A 40L backpack sits near the upper boundary of EasyJet's large cabin bag limit (56 × 45 × 25 cm). Soft-sided, compressible bags packed carefully will usually pass. Overpacked or rigid-frame designs may exceed the depth or width limit and risk being gate-checked. This tier requires a paid upgrade — pre-purchase online for the best rate.

This tool reflects real-world packing conditions, not just theoretical bag sizes. Results are based on typical clothing volumes, packing efficiency, and common travel setups.
EasyJet's large cabin bag limit is 56 × 45 × 25 cm. A 40L backpack is near this limit. Soft-sided bags packed carefully will usually pass, but overpacked or structured bags risk being gate-checked. Final acceptance depends on packed external dimensions, not listed volume.
This is a planning tool, not a guarantee. Airline staff make the final call — packed shape, bag rigidity, and gate-day enforcement all play a role.
