Frame Size Guide
When selecting eyeglasses or sunglasses at FramesDirect.com, it's helpful to know what size frame will fit you. You can find this information easily by looking at a pair of frames you may
currently own, or by visiting a local optical store.
In the event you already have a pair of frames that you would like to purchase again or even find a pair of frames similar, you can quickly identify the designer name, model number, and
frame size by simply looking on the inside of your eyeglass temples (arm pieces). Below you'll find a quick guide to helping you identify your eyeglasses.

Most prescription frames will have your exact measurements engraved on the temples (arm pieces) or behind the nose bridge area.
On the sample eyeglass frames below, it reads 52 17-150, which translates to an eye size of 52, bridge size of 17 and temple length of 150.
Note: Every frame has the same markings on the temples (arm pieces) or behind the bridge (nose area) as shown here:
