How to Measure the Frames of Your Favorite Glasses

 measure your glasses


Measurements of the Frame and Descriptions. (in  millimeters - mm)

When buying your new prescription glasses the best thing to do is to start with a plan and this should include the measurement of the glasses that you have worn in the past that fit you well. This will ensure that you get the right frames for your face - and yes you should also look at the shape of the frame and how it will compliment you face but start with the measurement!

Ever by a shirt or pants without looking at the size? It's the same thing with glasses. It is important to take into account all the various differences that come with a different size. 

And even though most glasses put the lens, temple and bridge size the best first gage is the overall width of the frames.

That's not to say that the other measurements are not important but the bridge width for example is on average around 15-20 mm. Even on the widest frame it may only have 16mm bridge - but the key is it may have adjustable nose pads. (More about how your glasses should fit) While you should look at the bridge - especially for plastic/acetate frames that have a set nose pad because if those are too wide they may just slip off - it's not as important as the width. 
The temples length too are adjustable - can be curved more around the ears, or less - to a very large extent so start with the width. Rest assured that usually the wider the frame the longer the temples will be.

For a wider face it's important to look at some
wider frames 140mm+. for a more narrower face it's better to look at the more medium sized frames with the width inbetween 130mm-139mm. And for smaller or younger faces the small sized frames are good and these are sized inbetween 118mm-129mm.

We use mm instead of inches so that we can get more precise when we are dealing with smaller spaces unlike with clothing where the garments are bigger.
