EasyJet’s cabin bag policy sounds simple: one small underseat bag included, larger cabin bags only if you pay extra. But the real problem isn’t the rules — it’s the sizer at the gate. That metal frame doesn’t care what the tag on your bag says. If the wheels stick out, you’re paying £48 at the gate. Here’s exactly what fits, what doesn’t, and the one measurement most people ignore until it’s too late.
What EasyJet Actually Allows (vs. What People Assume)
EasyJet runs two tiers for cabin baggage. The free allowance covers one small bag that fits under the seat in front of you. Dimensions: 45 x 36 x 20 cm. That’s it. No wheels, no overhead bin access, no exceptions for “but it’s mostly empty.”
The paid upgrade — what EasyJet calls a “large cabin bag” — gets you 56 x 45 x 25 cm and overhead locker space. This costs between £5.99 and £32.99 depending on route and when you add it. You can bring this plus your small underseat bag.
Here’s where people get stung: the 25 cm depth on the large bag includes handles, wheels, and any external pockets. A bag listed as “56 x 45 x 25 cm” on a retailer’s site might actually measure 28 cm deep once you include the wheel housing. That 3 cm gap is what separates a smooth boarding from a £48 credit card swipe at the gate.
The One Measurement Nobody Checks
Depth. Length and width are easy to eyeball. Depth is what kills you. Most “cabin-approved” bags are 20-22 cm deep internally, but the external measurement with wheels and handles pushes them to 26-28 cm. EasyJet’s sizers are rigid metal boxes. If your bag doesn’t drop in cleanly, you’re paying.
The other gotcha: EasyJet’s free underseat bag sizer is smaller than Ryanair’s. Ryanair allows 40 x 25 x 20 cm for their free bag. EasyJet gives you more volume (45 x 36 x 20 cm), but the 20 cm depth is strict. A thick backpack with a rigid frame will fail even if it’s within the height and width.
Who Gets Gate-Checked Most Often
Not everyone gets the same scrutiny. EasyJet gate staff tend to flag:
- Hard-shell wheeled bags on passengers who only paid for the free allowance
- Bags that look visibly thick from the side profile
- Passengers boarding late in the queue (overhead bins fill up)
- Anyone carrying a second bag that isn’t clearly a small handbag or airport purchase
If you’re in boarding group C or D with a chunky-looking bag, your odds of a sizer check go way up.
Bags That Actually Fit the Free Underseat Sizer
The free bag slot is the trickiest to shop for. Most bags marketed as “cabin bags” are designed for the 56 x 45 x 25 cm overhead size, not the 45 x 36 x 20 cm underseat slot. You need something specifically built for this constraint.
I’ve measured these against the EasyJet sizer dimensions (not just the manufacturer’s claims). All prices are current as of early 2026.
| Bag | Claimed Dimensions | Actual Depth (loaded) | Price | Fits EasyJet Free? |
|---|---|---|---|---|
| Cabin Max Metz 20L | 40 x 35 x 20 cm | 20 cm | £29.95 | Yes, with room to spare |
| Aerolite 40x20x25 | 40 x 25 x 20 cm | 20 cm | £24.99 | Yes, designed for Ryanair but works here |
| American Tourister Bon Air Spinner | 40 x 35 x 20 cm | 22 cm | £55.00 | No — wheels push depth over 20 cm |
| Samsonite Guardit 2.0 Backpack | 43 x 33 x 17 cm | 17 cm | £45.00 | Yes, slim profile is ideal |
The Cabin Max Metz is the safest bet. It’s cheap, it’s soft-sided so it squishes, and the 20 cm depth is accurate even when packed full. The Samsonite Guardit 2.0 is a nicer bag — better padding, more comfortable straps — and at 17 cm deep you’ll never get flagged. But it’s £15 more and holds slightly less.
Hard-shell wheeled bags in the “underseat” category are almost always too deep once you measure the full external dimensions. The American Tourister Bon Air is a great little suitcase, but it’s for Ryanair’s paid cabin bag, not EasyJet’s free allowance. Don’t get caught by the “cabin approved” label — that usually means overhead bin, not underseat.
Overhead Cabin Bags: The 25 cm Depth Problem
The paid large cabin bag allowance (56 x 45 x 25 cm) opens up way more options. But that 25 cm depth is still tighter than the industry-standard 55 x 40 x 23 cm that most “international carry-on” bags are built to. EasyJet gives you more width (45 cm vs 40 cm) and slightly more depth (25 cm vs 23 cm), which sounds generous — until you realise most mainstream cabin suitcases are 55 cm tall, not 56 cm. That extra centimetre in height doesn’t help you. The extra width does.
Here’s what works and what doesn’t:
- IT Luggage World’s Lightest 4-Wheel Cabin Case (£69.99, 55 x 40 x 20 cm) — Fits easily. Only 20 cm deep. You’re leaving 5 cm of depth on the table, but it’ll never get gate-checked.
- Cabin Max Manhattan 56x45x25 (£44.95) — Built specifically for EasyJet’s large cabin bag dimensions. Soft-sided, exactly 56 x 45 x 25 cm. Zero wasted space. The tradeoff: soft shell means less crush protection for fragile items.
- Samsonite S’Cure Spinner 55cm (£109.00, 55 x 40 x 20 cm) — Fits but wastes the width allowance. Excellent protection, but you’re paying for space you can’t use.
- American Tourister Soundbox 55cm (£79.99, 55 x 40 x 23 cm) — Fits. The 23 cm depth is safe. Hard shell gives good protection. But at 40 cm wide, you’re leaving 5 cm of EasyJet’s generous width allowance unused.
The Cabin Max Manhattan is the obvious pick if you want maximum volume within the rules. It’s not a pretty bag, but it’s the only one here built to the exact EasyJet spec. For a more durable option, the IT Luggage case is 20 cm deep — well under the 25 cm limit — and weighs almost nothing (1.5 kg). You sacrifice packing volume for peace of mind.
Soft vs. Hard Shell: What Survives the Sizer
Soft-sided bags win for budget airline compliance. Period. A soft bag can compress into a sizer. A hard shell can’t. If your hard shell is 26 cm deep and the sizer is 25 cm, you’re done. A soft bag at 26 cm deep can often be squished the extra centimetre — though don’t count on gate staff being generous about this.
The real advantage of soft bags isn’t just the sizer test. It’s the under-seat fit. EasyJet’s free bag goes under the seat in front of you. A hard-shell box doesn’t mould around the seat support bar. A soft backpack does. If you’re tall and need legroom, a rigid case under the seat is miserable.
Hard shells win on one thing: protection. If you’re carrying a laptop, camera gear, or anything crushable, a hard shell gives you peace of mind that a soft bag doesn’t. The Samsonite S’Cure is the best option here — the polypropylene shell is tough, and at 20 cm deep it fits EasyJet’s large cabin allowance without question.
For the free underseat allowance, skip hard shells entirely. The depth constraint is too tight, and the wheels eat into your volume. A backpack or soft holdall is the only sensible choice.
When You Should Just Check a Bag Instead
The EasyJet cabin bag upgrade costs up to £32.99 each way. A 15 kg checked bag costs between £9.49 and £35.99 depending on route and booking time. On some routes, checking a bag is cheaper than paying for the large cabin bag. Let that sink in.
If you’re travelling for more than 4-5 days, or you need toiletries over 100 ml, or you’re bringing anything bulky (boots, winter coat, gifts), do the maths before you automatically add the cabin bag upgrade. A checked bag plus your free underseat bag might cost the same or less — and you get 15 kg of capacity instead of squeezing everything into 56 x 45 x 25 cm.
The other scenario: if you’re flying EasyJet as part of a longer trip with other airlines, check whether your bag fits their rules too. A bag built for EasyJet’s generous 56 x 45 x 25 cm large cabin allowance won’t fit Ryanair’s 55 x 40 x 20 cm paid cabin bag. And it definitely won’t fit Wizz Air’s 55 x 40 x 23 cm. If EasyJet is just one leg of a multi-airline trip, buy for the strictest airline on your itinerary.
One last thing. The £48 gate-check fee is per bag, per flight. If you’re on a return trip, that’s £96. For that money, you could buy the Cabin Max Manhattan and the Cabin Max Metz and still have £21 left over. The bag that fits is always cheaper than the fee for the bag that doesn’t.
