Eyewear Size Guide
At Tom Miller, we understand that finding the perfect fit for your eyewear is essential for comfort and style. Our size guide will help you determine the right frame size for your face.
How to Measure Your Frame Size
Most eyeglass frames have three numbers printed on the inside of the temple (arm) that indicate the frame dimensions:
Lens Width
The width of one lens (usually 40-60mm)
Bridge Width
The distance between the lenses (usually 14-24mm)
Temple Length
The length of the temple/arm (usually 135-155mm)
Example: A frame marked 50-18-145 means lens width 50mm, bridge width 18mm, and temple length 145mm.
