Product Help

Help with frame sizes

Finding the correct frame size to suit you requires you to know a little about the different measurements that are used.  Size information is normally broken down in to arm / temple length (ranges between 120 - 150mm), bridge width (ranges between 14 - 24mm, and lens width (ranges between 40 - 62mm).  We also include a frame height measurement where possible, this can vary depending on frame style.

If you require further help, please do not hesitate to contact our customer service team on 03303 801 190 (Mon - Fri, 9am - 5pm) for further assistance.

I already have glasses, how do I find out their size?

If you have a pair of glasses that are a perfect fit, you can usually find the frame size information on the frame - usually on the arm or the bridge.
