Deciphering Frame Measurements

Frame measurements, commonly referred to as "frame size", are actually three different numbers measured in millimeters. These measurements include:

  • Eye Size: This is the width of the lens or the diameter of the glasses lens, measured from the bridge. The eye size in our collection ranges from 31mm to 53mm.

  • Bridge Size: This refers to the distance across the smallest part of your nose. It's the area that connects the two lenses. In our collection, the bridge size ranges from 11mm to 19mm.

  • Temple Size: This is the length of the arm- or the 'temple'- of the glasses, extending from the lenses to behind the ears. The temple sizes in our collection range from 112mm to 142mm.

How to Take Measurements

For a frame to fit properly, it should match the size and shape of your child's face. To take these measurements:

  • Eye Size: Measure the widest part of the lens from left to right. Ensure the tape measure is straight, and that it covers the full width of the lens. An eye size that fits perfectly should fall within the range of 31-53mm.

  • Bridge Size: This can be a bit trickier, but typically, it's the distance between the two lenses. Measure the area that would rest on the nose. A comfortable bridge size should be between 11-19mm.

  • Temple Size: Start the measurement from the hinge—where the arm connects with the lens frame—following the curvature of the arm to the very end. The tape measure should extend straight to the tip of the arm, without curving down behind the ears. This measurement is typically between 112-142mm in our collection.
