How to Measure Your Bag at Home Without a Tape Measure

It’s always tricky trying to decide whether your bag will meet the baggage allowance restrictions and fit in the dreaded baggage sizer at the airport.

Well, thanks to a hardly known feature that’s hidden away on the easyJet app, called the ‘cabin bag sizer’, you can check from home without the use of a tape measure!

Using 3D augmented reality, the tool uses your device’s camera to ‘scan’ your luggage and check whether it meets the airline’s baggage allowance.

Sounds complicated? Fortunately, it’s really easy to use!

Here's the baggage allowance and luggage limits for flight bookings with Ryanair, easyJet, Wizz Air, British Airways, Jet2 and TUI in 2023.

What is The EasyJet Cabin Bag Sizer App Feature?

The easyJet bag sizer App feature powered by Apple’s ARKit 2 technology and works with the phone camera to scan real-life luggage and determine whether the cabin luggage will fit easyJet’s baggage allowance measurements.

This actually isn’t new technology – easyJet released this feature back in 2019 however it’s gone under the radar for many. I only just discovered it!

The good news though, is that the dimensions it shows are up to date with what the airline currently allows on board.

Just me, or is it always easier to do something after watching someone else?!

Is the easyJet Cabin Bag Sizer App Accurate?

As long as you’ve followed all the instructions, you should get quite an accurate reading on whether your luggage will fit on your next easyJet flight.

However, easyJet does say:

"Customers should note that the app feature is indicative only  - customers remain responsible for ensuring their baggage strictly adheres to our allowances. Please see our baggage help page for full details.  We accept no liability for any fees the customer may have to pay if their cabin bag is oversized."

Does this defeat the point? Perhaps a little bit, yes. But what I like about the app is that it gives you a good visual reference for the shape of the baggage sizers that you may be asked to slot your bags inside at the airport.

Also, if you find yourself without a traditional way to measure your luggage, it’s definitely a clever hack to check you’re on the right lines.
