Suitcase size , Is mine to big

[TeaAndToast8]

Flying with Ryanair and I’ve paid for a large cabin bag. My husband is saying mine is too big. He thinks I need to curve the tape measure around the case more. What do you all think?

It looks as if it exceeds the 20cms.
They’re ruthless. If it doesn’t easily slide in and out of the sizer thingy they’ll charge you for it.

I think the 20cm side is very tight.

I think it's tight re the 20cm, do you have a slightly smaller one? Save hassles at check-in?

How annoying, this is what my husband said. I’ll have to buy a smaller one. It’s cheeky, Every other airline allows 25cm, my fault should have checked before booking.

The first photo is clearly 21cm, not 20.
