Ryanair Personal Item Size 2026: Will Your Backpack Fit?

Quick answer: Ryanair currently includes one small personal bag measuring up to 40 × 30 × 20 cm with all fares. It must fit under the seat in front of you. Nomadity's configured compressed backpack dimensions are within those measurements, but an overfilled flexible backpack can expand, so close every expansion zipper and measure the finished bag before departure.

What is Ryanair's free personal-item size?

Ryanair says all fares include one small personal bag with maximum dimensions of 40 × 30 × 20 cm. Examples include a handbag or laptop bag, and the item must fit completely under the seat.

Ryanair's paid Priority & 2 Cabin Bags option adds a second 10kg cabin bag measuring up to 55 × 40 × 20 cm for the overhead locker. That is a different allowance from the free small bag.

Which Nomadity backpacks match the Ryanair dimensions?

A dimension match is not an acceptance guarantee. Straps, handles, an overfilled front pocket or an open expansion zipper can make the measured bag larger. The gate agent judges the actual bag.

How to pack a vacuum backpack for Ryanair

1. Start with the fare: verify whether your booking includes only the small bag or also a 10kg cabin bag.
2. Compress only soft clothing: place shirts, trousers and knitwear in the sealed compartment.
3. Keep rigid items shallow: shoes and toiletry cases can create bulges even when clothing is flat.
4. Close the expansion zipper: the larger-capacity state is not the same as the compressed personal-item state.
5. Measure all three sides: include the fullest points, handles and straps.
6. Leave a margin when possible: a bag packed exactly to every limit offers no room for measurement variation.

Can the 60L Discoverer really fit a Ryanair sizer?

Nomadity has photographed the Discoverer—the largest model—inside an airport personal-item sizing bin. The relevant measurement is its compressed packed shape, not the expanded 60L capacity. This evidence represents the tested configuration; it does not mean every overfilled Discoverer will fit every Ryanair sizer.

See the Discoverer 60L packing guide for the load example and airport image.

How to avoid a Ryanair bag fee

The safest strategy is simple: know the allowance on your booking, pack to the smaller state, measure before leaving home and do not add last-minute items after measuring. Vacuum compression creates space, but it does not permit you to exceed Ryanair's dimensions or any applicable weight restriction.

Ryanair personal-item FAQ

How strict is Ryanair with personal-item size?

Ryanair publishes a fixed 40 × 30 × 20 cm allowance and can ask travelers to place bags in an airport sizer. Enforcement can vary by airport and flight, but the safest plan is to assume the limit will be checked and leave a small margin rather than relying on a flexible bag being squeezed into place.

Is a backpack free on Ryanair?

One small personal bag is included with all fares when it fits the 40 × 30 × 20 cm limit and goes under the seat. A larger cabin backpack may require Priority or another paid baggage option.

Does Ryanair measure backpacks?

Ryanair can require a bag to fit its sizer at the airport. Soft bags are not exempt, and straps or bulges count toward the real dimensions.

Is the Discoverer a 60L bag or a 40 × 30 × 20 cm bag?

Those numbers describe different things: 60L is the published expanded capacity; 40 × 30 × 20 cm is the configured compressed exterior used by Nomadity's checker.

Does compression make the bag lighter?

No. It removes air and reduces volume. The contents weigh the same.
