A frame has 4 basic frame sizes ( eye, bridge, temple, vertical ):
Most name brand eyeglass/sunglass frames have some size information printed on the inside of the frame, although the lettering can be worn away with use. To find all the lettering, you must look on the inside of both temples, and on the inside of the bridge. If the numbering has worn off use the below size chart to take the measurements ( in millimeters ) yourself. All four sizes ( eye, bridge, temple, vertical ) are color coded to make the size chart easier to read.
If you already own a eyeglass or sunglass frame, look on the inside of each temple to find the size of the frame...look at the image to the right. The Eye Size is always first then there a dash or a square the bridge size some space then the temple size. The vertical size is rarely on the frame.
Note: if the size is not on the temple look under the bridge.
In most cases a person's eyeglass frame is smaller than their sunglass frame, however if the styles of the frame are similar then the size might be similar. If the sunglass frame is a wrapped frame ( has a curve to it ) then usually the frame will fit a more wide-range of people.
In most cases, if you're looking to purchase an eyeglass frame you should use the size from a previous eyeglass frame you've owned. If you're looking to purchare a sunglass frame then you should use the size from a previous sunglass frame you've owned.
The best thing to do is go to a local store try-on some frames until you either find a frame you like then come back to our website to purchase that frame. If you find a frame you like make sure you look on the inside of the temple to find the model number and the size since frames do come in multiple sizes.
To know truly how big the frame is, meaning how will it look on your face you must determine the total frame width. The total frame width includes the endpieces, and the endpieces are never measured and specified. The endpiece refers to the width of the frame from the edge of the lens out to the edge of the frame where the temples are connected to the frame front. In most cases an endpiece is 2-6 mm for a total of 4-12mm for both.
Below are instructions on how to determine the best frame size for your face.
If you have the total width of the frame the best thing to do is subtract 6mm ( total average for both endpiece ). Find a frame that you like, take the eye size multiply by 2 then add the bridge size and that's the total width. If the total of the frame is plus or minus 2 of your total, then the frame might be a good size for you.
You can use the Quick Find tool on the top menu to search for all frames with a given Eye, Bridge, or Temple size.
