Hand Luggage Size Rules: UK Airlines Compared
Every UK airline sets its own hand luggage size rules, and the limits rarely match from one carrier to the next. A bag that travels free with Wizz Air can trigger a gate fee of £45 or more on Ryanair. Understanding exactly what each airline allows, in centimetres and kilograms, is the difference between walking straight to your gate and being stopped at the bag sizer.
This guide compares the free personal item and paid cabin bag allowances for the UK’s five busiest airlines, explains why the rules keep changing, and shows you how to pick a bag that clears every carrier at once.
Quick Answer: Hand Luggage Sizes at a Glance
| Airline | Free personal item | Paid cabin bag (larger) | Weight limit |
|---|---|---|---|
| Ryanair | 40 x 30 x 20cm (under seat) | 55 x 40 x 20cm (10kg, with Priority) | No weight check on the free bag |
| easyJet | 45 x 36 x 20cm (under seat) | Larger cabin bag with Up Front or Extra Legroom seats | 15kg |
| British Airways | 40 x 30 x 15cm (handbag/laptop bag) | 56 x 45 x 25cm (included on most fares) | 23kg for the larger bag |
| Jet2 | Small under-seat bag, included | Guaranteed Cabin Luggage, pre-bookable | Varies by fare |
| Wizz Air | 40 x 30 x 20cm (under seat) | 55 x 40 x 23cm (10kg, paid add-on) | 10kg for the larger bag |
These figures reflect 2026 allowances. Airlines revise dimensions periodically, particularly following EU aviation rulings on cabin baggage, so always check the airline’s own baggage page shortly before you fly.
Ryanair Hand Luggage Rules
Ryanair includes one small personal bag with every fare, free of charge, provided it fits within 40 x 30 x 20cm and slides under the seat in front. There is no separate weight check on this bag, only a size check at the gate sizer. Passengers who want a full-size wheelie case in the overhead locker need to add Priority boarding, which unlocks a second bag up to 55 x 40 x 20cm and 10kg. Anyone whose free bag fails the sizer at the gate faces a fee that regularly exceeds £45, so it pays to measure before you leave home.
easyJet Hand Luggage Rules
easyJet’s standard included bag is the most generous of the low-cost carriers at 45 x 36 x 20cm and up to 15kg, and it must also fit under the seat ahead. A second, larger cabin bag in the overhead locker is only guaranteed if you book an Up Front or Extra Legroom seat, or hold a Plus fare. Weight, not just size, is checked here, so an over-stuffed bag can be flagged even if it fits the sizer.
British Airways Hand Luggage Rules
As a full-service carrier, British Airways includes two cabin bags on most fares: a small handbag or laptop bag up to 40 x 30 x 15cm, and a larger cabin bag up to 56 x 45 x 25cm and 23kg. Economy Basic fares reduce this to the smaller bag only, with no checked allowance. First Class passengers are exempt from some of the tighter restrictions applied to Economy and Premium Economy.
Jet2 Hand Luggage Rules
Jet2 includes a small under-seat bag with every booking. A larger “Guaranteed Cabin Luggage” allowance can be pre-booked for a fee, which secures overhead locker space rather than leaving it to chance. Jet2 also reserves the right to place hand luggage in the hold when the cabin is full, so passengers should always keep medication, travel documents and valuables in the bag most likely to stay with them.
Wizz Air Hand Luggage Rules
Wizz Air’s free personal item matches Ryanair’s at 40 x 30 x 20cm. A larger 10kg cabin bag, up to 55 x 40 x 23cm, is available as a paid add-on and includes priority boarding. Wizz Air is known for consistent gate enforcement of these dimensions, so travellers connecting through multiple Wizz Air routes should size their bag to the smallest limit on their itinerary.
Why Hand Luggage Rules Keep Changing
Airlines for Europe, the trade body representing Ryanair, easyJet, Wizz Air and others, has been working with EU regulators to standardise cabin baggage. The current agreement guarantees passengers a free personal item of at least 40 x 30 x 15cm across member airlines, though several carriers, including Ryanair and easyJet, have chosen to offer more generous dimensions than the minimum. A separate proposal, still moving through the European Parliament, would guarantee two free cabin bags on every fare, but this has not yet become law. Until it does, the free allowance and any paid upgrade continue to vary by airline and even by fare type within the same airline.
How to Choose a Bag That Fits Every Airline
If you fly with more than one carrier, the safest strategy is to buy hand luggage sized to the smallest common limit rather than the most generous one. A bag no larger than 40 x 30 x 20cm will clear the free allowance on Ryanair, Wizz Air and most easyJet flights, and will also fit as the smaller item on British Airways and Jet2. For a case that also works as a larger paid cabin bag, look for dimensions close to 55 x 40 x 20cm, which sits within Ryanair’s Priority allowance and Wizz Air’s paid add-on.
Soft-shell bags with a small amount of give are more forgiving at gate sizers than rigid hard-shell cases built to the exact millimetre. Packing cubes also help you compress a bag that is marginally over, since removing air rather than items is often enough to pass a sizer check.
What Happens If Your Bag Doesn’t Fit
Gate staff use a rigid metal or plastic sizer, and a bag that bulges even slightly beyond the frame will usually be rejected, regardless of weight. On low-cost carriers this typically means an on-the-spot gate fee, often £40 to £50, and the bag is placed in the hold, sometimes without a gate-side guarantee that it will be handled with the same care as pre-booked hold luggage. To avoid this, remove liquids, chargers and any loose items that cause a bag to bow outward before you reach the gate, and check your airline’s page again if you haven’t flown with them in the past six months.
Hand Luggage and Liquids: The 100ml Rule
Across UK and EU airports, liquids, gels and aerosols must be carried in containers of 100ml or less, packed into a single transparent, resealable bag. This rule applies inside any hand luggage regardless of the bag’s overall size allowance, so a compliant cabin bag can still be delayed at security if the liquids bag itself is missing or overfilled.

Frequently Asked Questions
What is the smallest hand luggage size accepted by all UK airlines?
A bag measuring no more than 40 x 30 x 15cm will clear the free personal item allowance on every major UK airline, including British Airways, Ryanair and Wizz Air, since this matches the EU-agreed minimum dimension.
Do UK airlines weigh hand luggage?
It depends on the airline and bag type. Ryanair’s free personal bag is checked for size only, not weight. easyJet checks both size and weight, up to 15kg, on its included bag. Weight limits on larger paid cabin bags typically sit between 10kg and 23kg.
Can I take a laptop bag in addition to hand luggage?
On most airlines, a laptop or handbag counts as your one free personal item rather than an addition to it. British Airways is an exception on fares that include two cabin bags, where a laptop bag can be carried alongside a larger cabin case.
What happens if my hand luggage is oversized at the gate?
You will usually be asked to pay a gate fee, which is often more expensive than pre-booking a larger bag online, and the bag will then be placed in the aircraft hold for collection at your destination.
