frame size guide



The lens width (eye size) is measured from the bridge to the outer edge of the lens. The width of the frames should not be wider than the overall width of your face at the temples. It can be a matter of personal choice, but it's also determined by your frame style. 
Lens width usually varies between 40-62mm:

  • small lens width 40-50mm
  • medium lens width 51-55mm
  • large lens width 56-62mm


The lens height is measured from the top to the bottom of the lens. The top of your frame should be no higher than the line of your eyebrows. Again, it can be a matter of personal choice, but it's also determined by your frame style.


The bridge width is the horizontal distance between the lenses measured in the gap above your nose. It's important that this is comfortable. Too tight and the glasses could pinch your nose and sit too high, but too loose and the glasses could be unstable on your face and fall down your nose.
Bridge width usually varies between 14-24mm:

  • narrow bridge width 14-18mm
  • wide bridge width 19-24mm


The temple arm length is measured from the one extreme end of the frame arm/side to the other. This should be long enough to sit comfortably over your ears. Glasses with straight sides don't always have this measurement indicated.
Temple arm length usually varies between 120-150mm.




If you want to find the frame size of your current frames, it's normally printed on the inside of an arm piece or on the nose bridge area. 

For example 51-18-135
51mm = lens width,18mm = bridge width, 135mm = temple arm length



When looking for your frame size ignore a set of capital letters and numbers.
This is the model number and frame colour/style.



Eyeglasses and sunglass will normally be different sizes. Sunglass sizes are normally much larger than eyeglasses in order to give you more coverage from the sun and more protection.
