How to measure - LD framed window screens - m2m - Option 1 and 2

The instructions below explain how to measure for both a standard casement and a traditional sliding sash window.

In both cases we provide you with 2 ordering options.  Please ensure your measurements are entered in millimetres (mm).

Option 1.  Make my screen to A & B dimensions

Provide us with A (the width) and B (the height) that you require the outer edge dimensions of your screen frame to be.  Make sure you have made any allowances for your fitting method . Use the mesh & fixings tab to help you.

Option 2. Make my screen using A to F dimensions

Provide us with the dimensions of your window opening and surrounding framework and let us calculate the size of the screen for you.

The attached video explains in detail how to measure but the drawings below may also help.  If you have any obstructions on your framework that you are unsure how to overcome please contact us.


Standard Casement Window – side or top opener

Sash Window

Fitted to full sash – usually externally

Fitted to top or bottom opening sash

Fitted Internally to the lower or upper sash – Use the same principle as above for measuring either of the sashes

* The height of the screen can be the full height of the opening sash or the height to which you normally open your sash.

Depending on the style of your sash there may be a gap between frame D and the screen. This can be filled with UPVC trim, batten, adhesive pile seal or similar depending on the depth. Let us know if you need advice.
