Sizing / Measuring your windows for Flat Cats

Find out more about measuring your windows.


Flat Cats come in Standard, Custom, Small Custom and Door Screens. It is important to know which Flat Cat ® is best for your window to ensure a good fit.

To help you with this we have produced an easy to use sizing chart which you can print and complete. This will tell you, straight away, if the window in question needs a standard, custom or any other Flat Cat screen.

Customer comments

Hi Dominic, just to say a big Thank You for sorting out my order so quickly. Got them at work today and my first window is done. It was so easy to fit, and it's just lovely having the kitchen window finally open! My cat, Mickey, has been sitting on the sill getting some air. Have already recommended them to a friend.Brilliant idea, thank you again.

I have had flat cats from you a few years ago, and have now moved so have had to re order, so I can't wait! I've even told my new neighbour about them as they have said they would live to open their windows and never knew about them, so when I get them, I'm going to show them and they can order. I need to order a few more as well. But thank you as always for your quick service
