Ryanair Cabin Bag Rules: Size, Weight & Fees (2026)

Ryanair's baggage policy is one of the most talked-about in European aviation — and for good reason. The rules are more complex than most airlines, change periodically, and the fees for getting it wrong are steep. This guide explains exactly what you're allowed, what costs extra, and how to avoid being caught out at the gate.

The Two-Tier System Explained

Ryanair uses a tiered cabin bag system that depends on whether you have Priority Boarding. Understanding this distinction is essential.

Without Priority Boarding (Base Fare)

On a standard Ryanair ticket without Priority Boarding, you are entitled to:

• One small personal bag — maximum dimensions 40 × 20 × 25 cm
• This bag must fit under the seat in front of you
• Weight: carry-on policies state a reasonable personal weight, typically around 10 kg applies to combined bags

That 40 × 20 × 25 cm limit is quite small. It's roughly the size of a large handbag or a compact daypack. A typical cabin-sized rolling suitcase will not fit within these dimensions.

With Priority Boarding or a Cabin Bag Add-On

If you purchase Priority Boarding or a cabin bag option, you are allowed:

• One large cabin bag — maximum dimensions 55 × 40 × 20 cm — in the overhead bin
• One small personal bag — maximum dimensions 40 × 20 × 25 cm — under the seat
• Combined weight of both bags: maximum 10 kg

Priority Boarding is available during booking or post-booking in the My Ryanair section. It typically costs £/€6–15 per person per flight depending on route and how far in advance you book.

Recent Enforcement Crackdown

Since 2023, Ryanair has increased enforcement of its cabin bag policy at many European airports. What used to be a loosely enforced guideline is now actively policed at many gates, particularly at Ryanair's busiest hubs including Dublin, London Stansted, Madrid Barajas, and Rome Fiumicino.

The crackdown involves:

• Bag sizers at the gate. Ryanair staff use physical metal frame templates at many gates. If your bag doesn't fit in the sizer, it will be checked — at the gate charge rate.
• Stricter weight checks. Passengers with Priority Boarding may have their combined bag weight checked before boarding.
• Secondary checks. Some routes see secondary checks at the jet bridge itself.

This enforcement is not uniform — it varies by airport, route, season, and crew — but the risk is real and the fees are high enough to make compliance the only sensible approach.

Fees for Non-Compliant Bags

Getting your bag rules wrong on Ryanair is expensive. Here's what you'll pay:

Situation	Typical Cost
Cabin bag add-on (online, in advance)	£/€8–20 per flight
Priority Boarding (includes cabin bag)	£/€6–15 per flight
Gate check fee (bag too large for non-Priority)	£/€50–80 per flight
Checked bag (online, in advance)	£/€8–35 per flight
Checked bag at airport check-in	£/€40–70 per flight

The math is stark: buying a cabin bag add-on in advance costs 4–6× less than paying the gate fee. If you have any doubt about your bag size, buy the add-on before you get to the airport.

What Happens If Your Bag Is Too Big at the Gate

If Ryanair staff determine your carry-on exceeds the free personal bag dimensions and you don't have Priority Boarding:

1. You'll be asked to place your bag in the size template at the gate.
2. If it doesn't fit, you'll be given the option to pay the gate check fee.
3. Your bag will be checked into the hold and tagged to your destination.
4. You'll collect it at baggage reclaim on arrival.

Ryanair often doesn't have hold space reserved for gate-checked bags, meaning your bag may be placed on a later flight if the hold is full. This is rare but can happen on busy routes.

Tips to Avoid Ryanair Bag Fees

Measure your bag before leaving home. Use a tape measure across all three dimensions — length, width, and depth — including any bulges from packed contents. The template at the gate measures the bag as it actually is, not as the manufacturer claims.

Buy Priority Boarding if you have a rolling cabin bag. The economics are simple: a standard cabin suitcase won't fit in the 40 × 20 × 25 cm limit. If you're travelling with anything suitcase-shaped, you need Priority.

Pack light enough to use the personal bag only. If you can fit everything in a compact 20-litre backpack that fits within 40 × 20 × 25 cm, you avoid all fees entirely. Many experienced Ryanair travellers travel this way for short trips.

Check Ryanair's current policy before each booking. Ryanair updates its baggage rules periodically. The dimensions and included allowances have changed several times in recent years. Always verify on the Ryanair website rather than relying on cached information.

Use Ryanair's bag sizer guide. Ryanair publishes a template on their website that you can print and use to check your bag dimensions at home.

Book bags in the 'Extras' section. Bags booked during the initial checkout process are typically cheaper than those added post-booking. If you forget during checkout, add your bag as soon as possible — prices increase closer to the departure date.

The 10 kg Combined Limit

With Priority Boarding, the combined weight limit of 10 kg applies to both your bags together. This is worth planning for:

• A typical 55 × 40 × 20 cm soft-sided cabin bag weighs about 1.5–2 kg empty
• A typical 40 × 20 × 25 cm backpack weighs about 0.5–1 kg empty
• That leaves approximately 7–8 kg for your actual belongings

If you're travelling for more than 3 days, 7–8 kg of combined contents requires thoughtful packing. Consider a digital luggage scale to weigh your bag before leaving.

Exemptions from Ryanair Bag Rules

Certain items do not count against your cabin bag allowance:

• A coat or jacket carried (not packed)
• Baby food and equipment for infants
• Medications and medical equipment
• Mobility aids and wheelchairs (handled separately at check-in)
• Duty-free purchases in a sealed airport bag

Note that laptops must be removed from bags at security per standard EU airport rules, but they count towards your bag's weight once you've cleared security.

The Bottom Line

Ryanair's two-tier system rewards travelers who plan ahead. Non-Priority passengers get a single small bag that fits under the seat; Priority passengers (or those who add a cabin bag) get an overhead bag as well. The fees for non-compliance — typically £/€50–80 at the gate — far exceed the cost of pre-booking the right option. Check your bag dimensions carefully, buy the cabin bag add-on if you need it, and you'll have a smooth experience.
