Size Guide and Frame Measurments


It is important when purchasing your vintage glasses that the size of the frame is taken into consideration. All our frames have the measurements displayed for each frame on a tab called Measurements. The measurements displayed are the Lens Width, Bridge Width, Temple Length, Temple Width & Lens Depth. The measurements provided indicate the size of your glasses and are all recorded in millimetres.

Lens Width is the distance across the lens measured from the bridge. This distance can be dependent on the style of the glasses chosen, for example round glasses will have a smaller lens width. People with high prescriptions are better to keep the lens width as small as possible, as the greater the lens width the thicker the lenses.

Lens Depth is the depth of the lens at the greatest point.  A frame needs a minimum Lens Depth of 28mm to accommodate varifocals. 

Bridge Width is the distance between the lenses which sits across your nose. The greater the bridge width the wider the bridge across the nose. 

Temple Length is the length of the side from the dowel point to the end tip. Its important the side length is long enough to sit over your ear. 

Temple Width is the width of the frame across the inside of the front of the frame from temple screw to screw. This indicates the width of the frame, and is a great measurement to compare to your existing spectacles.
