Size and Fit guide

Choosing the perfect eyewear can be a complex process. This guide aims to give you a helping hand to find your best match. All eyewear has different functional and aesthetic characteristics. We use three main pieces of information to determine these attributes:

What is frame size?

The size of the frame counts as functional information, which is defined by one principal number:

  • Hinge to hinge distance: the width of the frame measured from the inside of the eyewear from the centre of each hinge.

How do I know the right size for me?

You can measure the hinge to hinge distance of a pair of glasses you already own with a ruler.

This information defines the following sizes:

Hinge to hinge (in) Hinge to hinge (mm) Size
<121< /th> <121< /td> XXS
121-124 121-124 XS
125-128 125-128 S
129-132 129-132 M
133-136 13-136 L
137-140 137-140 XL
>140 >140 XXL

Other measurements

If you already own a pair of glasses, you will see some numbers engraved on the inside of the eyewear temple, EG:


The first one is the Model name, then the Lens width and Bridge width. There is usually 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.

What’s the fit?

Fitting is aesthetical information which determines the amount of face coverage for a given size.

What are the bridge and nosepads?

This functional information describes the different types of the bridge and the nosepads. The four possible bridge and nosepads options are:

  • High bridge fit: offers a more secure and comfortable fit for those with a high nose bridge and lower cheekbones. A good choice if the bridge of your nose is above the level of your pupils.

  • Low bridge fit: offers a more secure and comfortable fit for those with a low nose bridge and higher cheekbones. A good choice if eyewear tends to slide down your nose, sit too low, or press on your temples or cheeks.

  • Universal fit: this option accommodates most face shapes.

  • Adjustable nosepads: nosepads that can be widened or narrowed to fit your unique nose shape.
