The most important dimension, the frame width, will not be printed on the temple arm. Follow our guide below to measure the frame width and ensure your new glasses are the right size for your face.
What Are The Frame Dimensions?
Specticles Frame Measurement
Measure horizontally across the entire front of the frame. Include any lug or hinge pieces that stick out on the sides.
Measure horizontally, at the top of the bridge, from the edge of one lens to the other.
Measure the lens vertically, at its tallest point. For bifocal or progressive prescriptions, the lens height must be at least 30 mm.
Measure from the hinge, where the arm connects in the front, to the spot where the arm begins to bend down around the ear. Then measure from the top of the bend to the bottom tip. Add the two sections together for the total temple arm length.
Measure the lens horizontally, at its widest point. Make sure the lens width accommodates your pupillary distance so that your eyes align with the “optical center” of the lens.
