Size Guide

Understanding eyeglasses measurements can help you find the perfect fit. Here's a quick guide to help decipher the most commonly used eyewear measurements.


Lens Width:

This is the width of each lens, measured horizontally at its widest point. For example, in the measurement sequence "49-21-140" the number 49 represents a lens width of 49 millimeters. Larger numbers mean bigger and wider lenses, while smaller numbers indicate smaller and narrower lenses.

 Bridge Width:

The bridge width is the distance between the two lenses, measured across the nose. Using the same "49-21-140" measurement, the 21 stands for a bridge width of 21 millimeters. Choosing a frame with a proper bridge width ensures comfortable placement on your nose.


Temple Length:

Temple length refers to the arm's measurement from the hinge to the part that rests behind your ears. Using the "49-21-140" example again, the 140 is the temple length measured in millimeters. Making sure that the correct temple length is being chosen ensures that the frame will stay secured to your face.


Lens Height:

Lens height measures the vertical distance from the top to the bottom of each lens. This measurement is not referenced as frequently as lens width, but it is equally important for individuals with specific vision needs. A larger lens height can provide more coverage area for multifocal lenses. If you see frame height being referenced instead of lens height, this is usually an indication that the upper and lower part of the frame are also included in the measurement. It is worth noting that unlike the three measurements above, you will usually not see a lens height measurement printed in the number sequence that is found on your frames. 


Frame Width:

The frame width measures the entire width of the glasses from one end to the other, including both lenses and the bridge. Finding frames with a suitable overall width helps to ensure the frames fit your face properly. Knowing the total frame width helps in selecting glasses that suit your face width and style preferences. As with the lens height measurement, the frame width is usually not included in the number sequence found on the frame.


Getting Your Measurements:

To find a new pair of glasses that fit well, first check your current pair. Often, the measurements are written on the inside of the temple arm. Look for a sequence of numbers like "49-21-140”. Using this information, you can make well informed choices when shopping for new glasses.

Remember, the right frame measurements ensure comfort, style, and optimal vision. Take these numbers into consideration to find eyeglasses that suit you perfectly.
