Can I Take A Rucksack As Hand Luggage With Ryanair? | Sizer

Ryanair’s bag rules are strict because space on board is tight. The good news: a rucksack works well, since soft sides let you compress it when a gate agent asks you to place it in the metal sizer.

This article shows how Ryanair treats rucksacks, what sizes match each fare, and how to pack so your bag still fits when it’s full.

Can I take a rucksack as hand luggage with Ryanair? What counts

Ryanair does not ban rucksacks. Your rucksack is treated like any other cabin bag: it must fit the allowance on your booking. The airline checks size, not bag style.

Two cabin bag sizes matter:

• Small personal bag: goes under the seat in front of you.
• 10 kg cabin bag: goes in the overhead locker when you have Priority & 2 Cabin Bags or a bundle that includes it.

Ryanair states that all fares include one small personal bag up to 40 × 30 × 20 cm that must fit under the seat, and Priority adds a second 10 kg bag up to 55 × 40 × 20 cm for the locker. Ryanair’s Bag Policy spells out those dimensions.

Rucksack, backpack, daypack: same rule

Call it a rucksack, backpack, school bag, or hiking pack. Ryanair still measures the outer dimensions, including stiff back panels, straps that stick out, and bulging side pockets.

A soft rucksack can be a smart choice for the free under-seat allowance, since you can flatten it a bit if you packed it tight. A rigid frame bag is tougher to squeeze into the sizer, even when it is only a little over.

What gate staff check

Most checks happen at the gate. A staff member may look at your bag and decide whether it needs to be sized. If they ask, you place it in the metal sizer. If it drops in without forcing it, you’re set.

Checks are more likely when a bag looks tall and boxy. A rucksack that sits close to your back and does not bulge draws less attention.

Taking a rucksack as hand luggage on Ryanair with Priority

Priority & 2 Cabin Bags lets you bring:

• One small under-seat bag up to 40 × 30 × 20 cm.
• One 10 kg cabin bag up to 55 × 40 × 20 cm for the overhead locker.

That second bag can be a rucksack too. A cabin-size hiking pack with a rectangular shape often fits the 55 × 40 × 20 cm box, yet you still want it to stay slim, since the locker depth is the tight part.

When Priority is worth paying for

Priority pays off when you want legroom back or you need a second bag for the locker. It can suit:

• Trips where shoes and toiletries would make an under-seat rucksack bulge.
• Work travel with a laptop plus a spare layer.
• Fragile items you don’t want gate-checked.

Bundle fares and what they include

Ryanair sells fare bundles that package bags and seats. The cabin-bag part is described in Ryanair’s help pages. Ryanair fare bundle options lists what each bundle includes, including the small cabin bag size and which bundles add checked baggage.

How to measure a rucksack so it passes the sizer

Measure a rucksack in its “real travel shape,” packed and zipped, with straps tightened.

1. Stand the packed rucksack upright.
2. Measure height from the base to the top of the bag body.
3. Measure width across the widest point.
4. Measure depth at the bulgiest point, often the middle.

Features that push you over

• Stuffed front pocket: depth jumps fast.
• Water bottle pockets: a bottle can add bulk.
• Hard laptop sleeve: some bags do not compress.
• External clips: they snag and add width.

If you’re close to the limit, shift bulky items inward and keep the outside smooth. A jacket worn on your body can save more space than moving small items around.

What happens if your rucksack is too big at the gate

If staff decide your bag does not fit your allowance, you can be charged a gate bag fee and the rucksack may be tagged for the aircraft hold.

Gate-checking can add delays. Your bag is taken at the gate, loaded into the hold, then you collect it at baggage reclaim. Keep medicines, passport, cash, phone, and spare lithium batteries in an inner pouch near the top so you can pull it out fast if needed.

If your bag is soft, you may be able to remove one item, compress it, and try the sizer again. Packing with that moment in mind can save money.

Try a home sizer test before travel day

If you have only flown with full-service airlines, Ryanair’s sizer can feel strict. You can take most of that tension out with a simple practice run at home.

Make a mock sizer box

Use masking tape on the floor to mark a rectangle that matches your allowance. For the free under-seat bag, mark 40 cm by 30 cm. Then stack books to make a 20 cm depth. Slide your packed rucksack into that space. If it fits without pushing hard, it will usually fit the airport sizer too.

Pack so you can shrink the bag on demand

Before you leave, do one last “squish test.” Put the rucksack on the floor and press the front panel in with both hands. If it gives easily, you have wiggle room. If it feels like a brick, remove one bulky item and wear it, or swap it for something softer. Keep the top pocket light, since a heavy top makes a bag stand tall and draws eyes at the gate.

Rucksack packing rules that keep you under the seat

Under-seat space is a low rectangle. A tall hiking pack can be awkward even when its volume feels right. Shape matters.

Pack for a flat front

• Dense items low: shoes, toiletry bag, charger.
• Soft items on top: tees, hoodie, scarf.
• Laptop against the back panel so the front stays flatter.

Try a simple home test: slide the packed rucksack under a chair. If it scrapes on the way in, it may scrape under an aircraft seat too.

Keep a reshuffle pocket

Leave one pocket half empty until boarding. If your bag looks puffy at the gate, move a couple of items into that pocket so the bag face stays flatter. Once you’re seated, you can rearrange.

Table: Ryanair bag options and where a rucksack fits

The table below maps booking choice to rucksack reality. Size limits shown are Ryanair’s stated maximums for the under-seat personal bag and the 10 kg cabin bag.

Booking choice	Cabin bags you can bring	Best rucksack match
Basic fare	1 small personal bag (40 × 30 × 20 cm)	Compact daypack that compresses
Regular fare	Small personal bag + 10 kg cabin bag (55 × 40 × 20 cm)	Under-seat rucksack + cabin-size rucksack
Priority add-on	Small personal bag + 10 kg cabin bag	Same allowance, bought as an add-on
Flexi Plus	Small personal bag + 10 kg cabin bag	Cabin-size rucksack with tidy straps
Family Plus	Small personal bag + checked bags in the bundle	Under-seat rucksack plus checked family bag
10 kg check-in bag	Small personal bag in cabin; 10 kg in hold	Under-seat rucksack for valuables
20 kg check-in bag	Small personal bag in cabin; 20 kg in hold	Small rucksack in cabin, main load checked
Lap infant booking	Cabin allowance differs; baby gear rules apply	Small rucksack with baby items split by pocket

Picking a rucksack that behaves like a cabin bag

If you buy a rucksack with Ryanair in mind, pick one that stays boxy when packed. A bag that collapses into a tube can look larger than its measurements.

Under-seat rucksack cues

• Flat front panel with fewer bulging pockets.
• Clamshell opening so you pack like a suitcase.
• Compression straps that pull depth in.

A 20–25 liter rucksack often works well for under-seat travel. Liters vary by brand, so treat volume as a rough hint and trust the tape measure.

Locker rucksack cues

• Straps that stow away or tighten tight.
• Rectangular back panel that stays flat in the locker.
• Light empty weight so you stay under the 10 kg cap.

Table: Fast checks before you leave for the airport

Use this sweep so you do not get stuck repacking at the gate.

Check	What to do	What it prevents
Measure packed size	Tape-measure height, width, depth with the bag full	“It fit empty” surprises
Smooth the outside	Empty bottle pockets, remove clips, tighten straps	Bag looking bigger than it is
Pull-out pouch	Passport, meds, cash, phone in one pouch near the top	Scrambling if hold-tagged
Wear the bulkiest layer	Put on jacket or hoodie before boarding	Extra depth from soft items
Reshuffle pocket	Leave one pocket half empty until the gate	No room to flatten the front
Know your booking	Confirm if you bought Priority & 2 Cabin Bags	Accidentally bringing a second bag

Small extras that can trip you up

Most problems happen when a traveler adds a second “little thing” that still counts as a bag.

• Camera bag
• Small tote
• Food bag from the terminal

If you are on a basic fare with one under-seat bag, put these items inside your rucksack before you reach the gate.

Checklist before you zip up

• My rucksack matches the cabin size on my booking.
• Straps are tightened and nothing sticks out.
• Liquids are in a sealed bag, and sharp items are not in my cabin bag.
• Power banks and spare lithium batteries are in my cabin bag, not a checked bag.
• Passport and phone are in a pull-out pouch.

Tick those off, and your rucksack should board with you and stay close from takeoff to landing.
