How To Find Glasses That Fit
I am looking at a pair of glasses on your site, how do I know they will fit me?
Great question! Nearly every pair of prescription glasses obtained in North America has sizing numbers written on the inside of the arms or on the bridge (the part that sits on your nose).
This is what the size numbers can look like on a given pair of glasses.
The first two numbers affect overall width. Those two numbers are the Lens Diameter (how wide each lens is across), and the Bridge Width (The space that sits upon your nose). You will also need to know the length of the arms called the Temple Length. Typically this number is in the 100’s with an average range of 125-150 mm.
The combination of the Lens Diameter (Width), Bridge Width and Temple Length give us an indication of your Perfect Fit (read further for instructions on using our Sizing Tool).
If I can’t find the sizing numbers on the glasses that I have what then?
You can also measure any glasses that you have to determine their size. In millimeters simply measure the Lens Diameter, Bridge Width and Arm Length (see image above for reference) and then enter these measurements into the Sizing Tool.
How do I use the Sizing Tool?
Once you have obtained the Lens Diameter, the Bridge Width, and the Temple Length, you can simply input these numbers into our Sizing Tool on the http://www.coastal.com/glasses page.
This will then narrow your search to the top frames that will best fit you (please note that frames sizes do not usually have to be exact, numbers within a few mm in either width or length should still fit). You can then further refine your search by Best Fit, Featured Products, Product Names and Price.
