How to Size Eyeglass Frames

Eyeglasses are a necessary accessory that millions of people need to wear everyday. Even if you are a contact wearer you will need a back-up pair of glasses in case you lose a contact or are unable to wear them all day. It’s important to find a pair that fits properly and flatters your face.


1 When shopping for new eyeglasses take a trusted friend or relative with you. Someone you can count on for an honest opinion. This is helpful because, unless you wear contacts, you will have to take off your glasses to try on the new frames and you may not be able to see yourself clearly to make the best choice.

2 Try on the glasses and look straight in the mirror. Do the frames stick out beyond your face? If so, choose a smaller size. You want the width of the glasses to be the same width as your face. If the glasses are too narrow you will be able to see the temples bowing out on each side. This will be uncomfortable as they will end up squeezing your head and possibly causing headaches.

3 Next, look at the glasses in relation to your brow line. There should never be a space between the top of the frames and your eyebrows. This causes a “double brow” effect and the result is unflattering on anyone. If the glasses have an adjustable nosepiece it will be possible for the optician to raise or lower the glasses some to make them the correct height. If the nosepiece isn’t adjustable, however, they must sit at the correct height when you first try them on.

4 Look at the nosepiece carefully. It should fit securely on the bridge of your nose with out pinching or visible gaps. Be sure to move your head up and down and side to side. The glasses should stay in place and not slip easily.

5 Now look at the temples. The curve should begin just about behind your ear. The optician will be able to adjust them but if the length isn’t pretty close to begin with they might become uncomfortable over time.

6 When you have found a pair or two that meet the size requirements take a look at the numbers on the frame, usually found on the temple or price tag. The frame and nosepiece width are listed together in centimeters. For example, 54/18. The temple length is listed separately (e.g. 140). These numbers will tell you approximately what size you should be looking for and will help narrow your search more quickly.
