I’ve been caught by Ryanair’s baggage rules more times than I care to admit. Nothing ruins a trip faster than that sinking feeling when the gate agent eyes your backpack suspiciously. Trust me, understanding their 40x25x20cm requirements isn’t just helpful—it’s essential for your wallet and peace of mind. With a few smart packing strategies and the right bag choice, you’ll breeze through boarding while others scramble to pay those dreaded £25 fees. Want to know how I now travel fee-free?
Ryanair’s Current Backpack Size Requirements

When flying with Ryanair, you’ll need to know their exact backpack requirements to avoid those pesky extra fees.
Your backpack must measure no more than 40 cm in height, 25 cm in width, and 20 cm in depth to qualify as free hand luggage.
Stick to these exact measurements: 40 x 25 x 20 cm, or pay up for that “free” carry-on!
Trust me, I’ve learned this the hard way! Your bag must fit under the seat in front of you. If it doesn’t, you’re looking at a £25 charge – that’s about $35!
If you’re bringing a larger backpack, consider priority boarding. This lets you bring an additional carry-on up to 55 cm x 40 cm x 20 cm.
Free vs. Priority Boarding Luggage Options

Ryanair’s luggage policy gives you clear choices between free and priority boarding options.
I’ve found that knowing these differences can save you both money and stress at the airport!
- Free ticket travelers can bring one small bag (40x25x20cm) that fits under the seat.
- Priority boarding lets you bring that small bag PLUS a 10kg cabin bag (55x40x20cm).
- Priority costs about £6-£12 extra but can save you the £25 gate fee.
- Your small backpack counts as your free bag, so choose wisely!

Tips for Choosing the Perfect Travel Backpack

Finding the perfect backpack for your Ryanair journey can make or break your travel experience!
I’ve learned that measuring is essential—look for bags specifically labeled as “Ryanair-compliant” or that fall within 40x25x20cm dimensions.
Consider bags with compression straps to squeeze down bulkier items. Soft-sided backpacks offer flexibility when slightly overstuffed.
Don’t forget multiple compartments for easy access to travel documents and essentials!
My top tip? Invest in a backpack that’s versatile enough for daily use at your destination.

How to Avoid Unexpected Baggage Fees at the Gate
Nothing bursts your travel bubble faster than facing a €25 fee at the gate because your backpack is just a smidge too big!
I’ve been there, and trust me, it’s not how you want to start your getaway.
Here’s how to fly fee-free with Ryanair:
- Measure your backpack before leaving home (40x25x20cm is your magic number)
- Pack light and compress your bag to fit under the seat
- Consider priority boarding if you need that extra carry-on
- Wear your bulkiest items (jacket, boots) instead of packing them
Conclusion
I’ve navigated Ryanair’s luggage maze countless times, and I’m telling you—preparation is your golden ticket! Think of their size restrictions as a puzzle you can master. With the right backpack hugging your shoulders and compression straps working their magic, you’ll breeze through the gate while others scramble to pay those pesky fees. Remember, in this high-flying game of inches, measuring twice saves you twenty-five pounds!
