Size guide

Choosing the right eyewear can be a complex process. This guide will help you find your best match.

What's the frame size?

The frame size refers to the horizontal width of the frame, measured between the centre of the left and the right hinge. Our frames come in one or multiple sizes. See the range in the chart below:

How do I find the right size?

To find your correct frame size, use a ruler to measure the hinge-to-hinge distance of a pair of glasses you already own that fits you well. Consider the tolerance range of +/- 4mm.

Other measurements

If you already own a pair of glasses, you will see numbers engraved on the inside of the eyewear temple. Those numbers will tell you the following:

The first one is the Model name, then the Lens width and Bridge width. There is usally a third number which represents the Temple Length, which is the measurement in millimeters of the 'arms' of the frame. Sometimes there is also a fourth number which is the Lens Height.

Each of these numbers is measured in mm.
