How to find the measurements of your old frames
Most of the time the frame measurements are engraved on the inside of your eyeglass temples (arm pieces) or behind the nose bridge area.
For instance, these will be shown as:
The first number represent width of lens
Second represent lens width
Third one is Temple length
Forth is bridge size

Frame Dimensions
In case you already have an eyeglass frame, you can refer to its frame size. These measurements don’t have to be exact but can vary from your existing frame size as follows:
Lens Width: within 2 mm | Bridge size: within 1 mm | Temple size: within 5 mm
Fit | Eyeglasses | Sunglasses |
---|---|---|
Small | 50mm and below | 55mm and below |
Medium | 51mm–54mm | 56mm–64mm |
Large | 55mm and above | 65mm and above |
Face Type
Each individual has different facial features and require different frame measurements. Moreover, frames vary by their shapes and sizes.
