Choosing the right Ryanair cabin bag can prevent an unpleasant surprise at the boarding gate. This guide separates the airline’s free underseat allowance from its larger Priority cabin-bag allowance, then compares two suitable options using their published external dimensions.

Ryanair cabin-bag allowance at a glance

AllowanceMaximum sizeWeightWhere it goes
Free personal bag40 × 30 × 20cmNo numerical adult limit stated in the policy; it must be manageableUnder the seat in front
Priority 10kg cabin bag55 × 40 × 20cmMaximum 10kgOverhead locker
Paid 10kg checked bagCheck the booking conditionsMaximum 10kgBag drop before security; carried in the hold

Every Ryanair fare includes one free personal bag measuring up to 40 × 30 × 20cm. Passengers purchasing Priority & 2 Cabin Bags can also bring a second bag measuring up to 55 × 40 × 20cm and weighing no more than 10kg. A paid 10kg check-in bag is different: it must be taken to bag drop and travels in the aircraft hold.

Read the current Ryanair bag policy before travelling. Airline rules and charges can change, and the allowance attached to your booking is the one that matters.

Best Ryanair cabin bags: quick comparison

BagPublished dimensionsAllowanceBest for

Dimensions should include wheels, handles and other protruding parts. Amazon listings sometimes combine several sizes or variants on one page, so check the dimensions of the exact option selected before ordering.

Best free Ryanair personal bag: Xkdoai underseat backpack

Xkdoai underseat backpack for the Ryanair free personal-bag allowance
  • Published dimensions: 40 × 25 × 20cm
  • Published capacity: Approximately 20 litres
  • Suitable allowance: Ryanair’s free 40 × 30 × 20cm personal bag
  • Style: Soft-sided backpack with compression straps and suitcase-style opening

This backpack was originally designed around Ryanair’s former 40 × 25 × 20cm allowance. Those measurements remain within the current 40 × 30 × 20cm limit when the bag is correctly oriented, although newer 40 × 30 × 20cm bags can use an additional five centimetres of width.

A soft backpack is useful for the free allowance because it avoids losing internal space to wheels and a telescopic handle. Compression straps can help control the shape, but they do not make an overfilled bag automatically compliant. It must still fit fully inside the relevant sizer and under the seat.

Best Ryanair Priority cabin case: Samsonite S’Cure Spinner 55

Samsonite S'Cure Spinner 55 cabin case for Ryanair Priority
  • Required model dimensions: 55 × 40 × 20cm
  • Suitable allowance: Ryanair Priority 10kg overhead cabin bag
  • Style: Four-wheel hard-shell cabin case
  • Important: Select the non-expanded 55 × 40 × 20cm variant and confirm all measurements on the current listing

The S’Cure Spinner 55 is the more conventional suitcase option for travellers purchasing Priority. A hard shell protects the contents and the four wheels make airport movement easier, but the case must remain within the 10kg limit and the wheels and handles count towards its external dimensions.

Do not assume every Samsonite case carrying “55” in its name has the same depth. Some expandable or alternative variants exceed 20cm. Only the exact 55 × 40 × 20cm version matches Ryanair’s stated Priority dimensions.

How to choose the right Ryanair cabin bag

Choose the allowance before choosing the bag

If you are travelling on the basic fare without a baggage upgrade, shop specifically for a bag no larger than 40 × 30 × 20cm. A standard cabin suitcase is normally too large for this free allowance. If you have purchased Priority & 2 Cabin Bags, you can also take a 55 × 40 × 20cm bag weighing up to 10kg.

Use external rather than internal dimensions

Retailers may emphasise capacity, screen size or the height of the main shell. For airline compatibility, you need the complete external dimensions, including wheels, fixed handles, feet and pockets.

Allow for an overfilled soft bag

A soft bag may be sold within the correct measurements but expand beyond them when tightly packed. Test the packed bag at home and leave enough flexibility for it to fit comfortably inside a baggage sizer.

Check the exact Amazon variant

Amazon product pages can combine different colours, capacities and sizes. Recheck the title and dimensions after selecting a variant and before completing the purchase. A similarly named model is not necessarily the same size.

Does Ryanair measure cabin bags?

Ryanair does not state that every passenger’s bag will be measured. However, a bag that does not fit the relevant baggage sizer can be refused at the gate or placed in the hold for a fee where available. There is no guaranteed tolerance, so buying and packing within the published dimensions is safer than relying on a bag being overlooked.

Read Ryanair’s current guidance on oversized bags at the boarding gate. Charges vary, so use the airline’s official fee table rather than relying on a fixed figure quoted in an older article.

Packing tips for Ryanair flights

  • Measure the bag after packing it, including pockets and protruding items.
  • Do not pack a soft bag so tightly that it exceeds its stated depth.
  • Wear bulky footwear and outer layers rather than using limited bag space.
  • Use compact packing cubes if they help organise the available space, but avoid overfilling.
  • Weigh the Priority bag at home and leave a margin below 10kg.
  • Check your booking confirmation to ensure the intended baggage option is included.
