You're standing in the queue at Gatwick. It's 5:00 AM. You've got a coffee in one hand and your passport in the other, feeling pretty good about life because you managed to snag a flight for the price of a fancy pizza. Then you see it. The "blue box" of doom. An easyJet ground crew member is eyeing your backpack with the intensity of a hawk. If that bag doesn't slide into the metal sizer without a fight, your "cheap" flight just got £48—or even £60—more expensive. Honestly, understanding the easyJet travel bag size rules is less about packing light and more about tactical survival in the world of low-cost aviation.
Air travel has changed. A lot. It used to be that a "carry-on" was just a carry-on, but easyJet has split their cabin bag policy into two very distinct camps: the "Small Cabin Bag" and the "Large Cabin Bag." If you haven't flown with them since the policy overhaul in early 2021, you might be in for a nasty surprise at the gate.
The Small Cabin Bag: Your Only Free Ticket
Let's talk numbers. Everyone—and I mean everyone—gets one small cabin bag for free. The maximum easyJet travel bag size for this freebie is 45 x 36 x 20 cm. That includes handles and wheels. Don't think for a second that a soft duffel bag is an exception; if the fabric bulges out past those dimensions, it counts as a fail.

Why such a weird, specific size?
It’s designed to fit under the seat in front of you. This is the crucial bit. If your bag has to go in the overhead locker, and you haven't paid for that privilege, you’re technically breaking the contract of carriage. EasyJet is famously strict here. They don't care if the plane is half-empty. They care about the turn-around time. Bags under seats mean faster boarding.
Does weight actually matter?
Surprisingly, easyJet is one of the more generous airlines when it comes to the weight of your cabin luggage. While rivals like Ryanair or Emirates might cap you at 7kg or 10kg, easyJet allows up to 15kg. You could technically pack a bag full of lead weights as long as it fits in that 45cm slot. Just make sure you can actually lift it. If you're struggling to carry it casually, you're drawing attention to yourself. That's the first rule of budget travel: don't look like you're struggling.
The Large Cabin Bag: The "Upfront" Perk
If you need more space—maybe for a week-long trip to Mallorca or a business stint in Berlin—you’ll need the Large Cabin Bag option. This pushes your easyJet travel bag size limit up to 56 x 45 x 25 cm.
But here is the catch. You can't just show up with it. You have to buy it. Usually, this comes as part of booking an "Upfront" or "Extra Legroom" seat. Alternatively, if you are an easyJet Plus cardholder or you've booked a FLEXI fare, you get this larger bag included. It goes in the overhead locker.
Think of it this way:
The small bag is a backpack or a large handbag.
The large bag is your standard "trolley" case with wheels.
If you try to sneak a trolley case on as your free small bag, you will get caught. The ground staff do this all day. They can spot a 55cm bag from across the terminal. It’s basically their superpower.
What Happens if Your Bag is Too Big?
It’s a nightmare scenario. You're at the gate, the beep goes off, and the agent asks you to step aside.
If your easyJet travel bag size exceeds the limit at the check-in desk, it’s usually around £40 to check it into the hold. But if you wait until you're at the boarding gate? That price jumps. We are talking £48 to £60 depending on the route and the day. At that point, you’ve likely paid more for the bag than the seat.
And they won't let you just "stuff it in." If it doesn't fit the sizer comfortably, it's going in the hold. You’ll be standing there in the middle of the jet bridge, frantically pulling out your laptop, chargers, and snacks because you aren't allowed to check lithium batteries into the aircraft hold. It’s embarrassing, it’s slow, and it’s expensive.
Selecting the Right Gear
You need to be precise. "Standard" backpacks are often 50cm tall. That's 5cm too big.
Many frequent flyers swear by specific bags like the Cabin Max Manhattan or the Aerolite Mini Case. These are built specifically for the easyJet travel bag size of 45 x 36 x 20 cm. They maximize every single millimeter of that under-seat space.
If you're using a bag you already own, measure it at home. Use a hard measuring tape, not a floppy sewing one. Measure to the widest points. If your bag has "compression straps," use them. Tighten them until the bag looks like a brick.
The "Squish" Factor
Hard-shell suitcases are risky for the small bag category. If it’s 46cm, it’s 46cm. It won't bend. Soft-sided bags, however, give you a bit of "squish factor." If your bag is slightly over but it’s mostly clothes, you can usually shove it into the metal sizer. Just don't overpack it to the point where the seams are screaming.
Real-World Tips from the Tarmac
I’ve spent way too much time in airports. Here is what I’ve noticed about how easyJet actually enforces the easyJet travel bag size rules.
- The "Look" Test: If you are wearing a massive winter coat and carrying a tiny bag, you look like a pro. If you're wearing a thin t-shirt and your bag looks like it’s about to explode, you're getting pulled over. Wear your heavy layers. Put your heaviest shoes on your feet, not in the bag.
- The Duty-Free Loophole: You are allowed one bag of duty-free in addition to your cabin bag. This is a classic "hack," but don't abuse it. If you try to stuff a second handbag into a Chanel carrier bag, most agents will see right through it.
- Check-in vs. Gate: Sometimes, if the flight is really full, they’ll ask for volunteers to put their large cabin bags in the hold for free. This is great if you don't mind waiting at the luggage carousel at the other end. But this only applies to the large bags. They almost never ask to take the under-seat bags because those don't take up locker space.
Complexity of "Add-ons"
EasyJet's pricing is dynamic. The cost of adding a large cabin bag isn't fixed. On a Tuesday morning flight from London to Amsterdam, it might be £12. On a Friday evening flight to Ibiza? It could be £35.

You have to do the math. Sometimes it’s actually cheaper to book a "Standard Plus" package than to buy a "Standard" ticket and add the bag later. This package usually includes the large cabin bag, a specific seat selection, and Speedy Boarding.
Practical Next Steps for Your Flight
Don't leave this until the morning of your trip. The "I'll just wing it" strategy is how airlines make their record profits.
- Audit your bag today: Get the measuring tape out. If it’s 45.5cm, it’s too big. Find a bag that actually meets the 45 x 36 x 20 cm requirement.
- Check your booking confirmation: Look for the bag icons. If you see one bag icon, you're on the small bag limit. If you see two, you've got the overhead locker space.
- Download the easyJet app: They have an Augmented Reality (AR) bag sizer tool. You point your phone camera at your bag, and it overlays a virtual box to see if it fits. It’s surprisingly accurate, though I’d still trust a physical tape measure more.
- Pack strategically: Heavy stuff at the bottom, essentials (liquids and electronics) at the top. If you do get asked to check the bag at the last second, you need to be able to rip your laptop and passport out in three seconds flat.
- Consider the "Hands-Free" option: For a small fee (usually around £7), you can drop your large cabin bag at the "Bag Drop" desk and they’ll put it in the hold for you. It saves you lugging it through security and gives you priority delivery at the carousel.
The reality of modern travel is that the "base price" is just an invitation. The easyJet travel bag size is the gatekeeper of your total holiday cost. Measure twice, pack once, and keep that extra £60 for some decent tapas when you land.
