Ryanair Bag Policy Explained: The 2+1 System (2026)

Ryanair's bag policy is one of the most discussed — and most misunderstood — in aviation. The core structure is simple but the small bag dimensions trip up a lot of travellers.

Here's exactly how it works.

The Two-Tier System

Ryanair operates a two-tier bag policy based on whether you have Priority Boarding:

With Priority Boarding

You can bring two bags into the cabin:

1. One cabin bag — up to 55×40×20 cm, max 10 kg — stored in the overhead bin
2. One small personal bag — up to 40×20×25 cm — stored under the seat in front of you

Without Priority Boarding

You can bring one bag into the cabin:

1. One small personal bag — up to 40×20×25 cm — stored under the seat only

Your cabin bag will be taken at the gate and checked into the hold. This is free at the gate if Ryanair requests it, but if you try to bring a cabin bag you didn't pay for, you'll be charged a gate bag fee.

The Bag Dimensions in Detail

Cabin Bag (requires Priority)

Dimension	Limit
Height	55 cm
Width	40 cm
Depth	20 cm
Weight	10 kg

The 20 cm depth is the dimension that catches most travellers. Many bags marketed as "carry-on" measure 23-25 cm deep — comfortably within US airline limits, but too large for Ryanair's overhead bin.

Small Personal Bag (all passengers)

Dimension	Limit
Height	40 cm
Width	20 cm
Depth	25 cm

Note: the small bag's stated dimensions are 40×20×25 cm — but many travellers misread them because the order is different from the cabin bag (which is 55×40×20). The 25 cm here is the depth, and the 20 cm is the width. This causes confusion when travellers try to compare the two bags.

Adding Priority Boarding: Cost and Timing

Priority Boarding is what unlocks your overhead cabin bag. You can add it:

At booking: cheapest option, typically 6-8 euros per flight depending on route and demand.

After booking online: still cheaper than at the airport, available in your booking management section.

At the airport check-in desk: more expensive, varies by airport and staffing.

At the gate: most expensive. Ryanair gate staff can add Priority, but the fee jumps significantly. Don't plan on doing this.

If your only reason for adding Priority is to bring a cabin bag, factor in the per-flight cost across your itinerary. On a return trip that's two flights, so two Priority add-ons.

Common Mistakes and Gotchas

Confusing the small bag dimensions. The small bag limit is 40×20×25 cm. Many travellers see "40×20" and think it means 40 cm tall and 20 cm deep. The 25 cm is the depth. An A4 document in a folder is roughly 30 cm tall — meaning typical laptop bags at 30-35 cm tall don't even fit as a Ryanair small bag without being compressed or tilted.

Buying a bag that's 55×40×23 cm. Ryanair's cabin bag depth limit is 20 cm. A bag that's 23 cm deep — which passes Wizz Air, easyJet, and virtually every other airline — does not pass Ryanair's bag sizer. This is a common source of gate-check fees.

Assuming Priority transfers between passengers. Priority Boarding is per passenger. If you have Priority and your travel companion doesn't, they cannot bring a cabin bag into the overhead bin.

Not checking in online. Ryanair charges for airport check-in. Check in via the app or website before your travel day.

What Priority Boarding Actually Buys You

Aside from the cabin bag allowance, Priority Boarding means you board in the first group. On busy routes this means:

• Access to overhead bin space before economy passengers board
• More time to settle, arrange your bags, and find your seat
• Reduced stress on the jet bridge

For travellers using Ryanair regularly, Priority on every flight is usually worth the cost simply to eliminate the cabin bag risk.
