Frame Measurement Guide

Frame Size

The sizes you can see with each of the frames on this website are of the same format. They are all given in millimetres, and the numbers are separated by a /. For example 46/20/135.

• The first number is the lens diameter.

• The second is the bridge width.

• The third will be the arm length.

To help with this, we have displayed against most frames, who they would be more suitable for (Small, Medium and Large).

What Frame Size is Right for You ?

The easiest way to select a suitable frame size is to get the dimensions from a comfortable pair of glasses that you already have.

Most commonly you find 3 measurements on one of the arms (perhaps with the help of a magnifying glass), the first two measurements usually being separated by a rectangle – but not always.

On one of the sides or on the bridge you will usually find 3 x measurements - the first 2 measurements are usually separated by a rectangle.

The Lens Diameter is a matter of choice, but the other two will determine the fit.

They do not need to be exact, but the closer they are to your existing comfortable pair, the more likely your new glasses are to be a comfortable fit.

These sizes can sometimes also be located:

1) On the inside of the bridge

In this case the last dimension (arm length) appears to be missing but it is infact shown separately on the leg (the arm length will generally be either 130, 135, or 140

2) Under the bridge on the nose rests.

Will a frame suit me?

The most important part of the frame that determines whether the frame will suit you is the shape of the eye pieces.

After that the overall width of the frame is the most reliable indication of whether the glasses will suit your face. The overall width of the frame will be approximately double the width of the eye piece plus the width of the bridge.

To help with this, we have indicated with most frames who they would be most suitable for (Small, Medium and Large faces).
