How to Choose the Right Frame Size
Selecting the right eyeglass size ensures comfort, proper fit, and optimal vision.
Here’s a guide to help you find the perfect match:
Key Eyeglass Measurements:


Standard Size
- Frame Width: Total width of the frame, including the lenses and bridge.
- Small: Frame width ≤ 135mm.
- Medium: Frame width 136-140mm.
- Large: Frame width ≥ 141mm.
Other Useful Measurements
- Lens Width: Width of a single lens (e.g., 50mm).
- Bridge Width: Distance between the lenses (e.g., 18mm).
- Temple Width: Length of the arms that rest behind your ears (e.g., 140mm).
If You Already Have Glasses
Check Existing Frames:
Look for numbers printed on the inside of the temple arms or bridge (e.g., “50-18-140” =
lens width, bridge width, temple length).

Measure Your Face
- Pupillary Distance (PD): Use a ruler or an app to measure the distance between your pupils. Most adults have a PD of 54–74mm.
- Face Width: Measure the widest part of your face (typically across the cheekbones). Compare these to frame dimensions (e.g., a narrow face suits smaller lens widths).
Pro Tips
- Comfort Check: Frames shouldn’t pinch your nose or slide down. The temples should rest lightly on your ears.
- Adjustments: Opt for adjustable nose pads or flexible temples for a customized fit.
- Frame Shape: Understanding your face shape is essential when choosing glasses, as the right frames can enhance your features and create balance. Use our face shape detector to identify Your face shape!
