Frame Size Guide
Use your full frame width (the total width across the front of your glasses) as the main guide, then cross-check your lens, bridge, and temple numbers — usually printed inside the arm, e.g. 49 ▢ 18 140.

Enter the full frame width from a comfortable pair you already own:
Tip: If you only have lens and bridge numbers, estimate full width as 2 × lens + bridge + 4–6 mm (hinges).
| Size | Full Frame Width (mm) | Lens Width (mm) | Bridge (mm) | Temple (mm) | Typical Fit |
|---|---|---|---|---|---|
| Extra-Small | < 125 | < 44 | < 16 | < 130 | Children / very narrow faces |
| Small | 125 – 130 | 45 – 47 | 16 – 17 | 130 – 135 | Petite or small-to-medium faces |
| Medium | 131 – 135 | 48 – 50 | 18 – 19 | 136 – 140 | Average adult fit (most common) |
| Large | 136 – 140 | 51 – 53 | 20 – 23 | 141 – 150 | Medium-to-broad faces |
| Extra-Large | > 140 | > 54 | > 23 | > 150 | Broad faces / oversized style |
How to measure your frame
- Lay your glasses flat, face-up on a table.
- Measure straight across the front, hinge to hinge — that’s your full frame width.
- Check the inner arm for numbers like 49 ▢ 18 140 to confirm lens, bridge, and temple size.
This is a general size guide for reference. Depending on the frame style or brand selected, some variation may occur.
Fit tips
- If your current pair fits perfectly, pick a frame within ± 2 mm of its width.
- Thicker or darker frames may feel snugger than thin or transparent ones.
- Adjustable nose pads are ideal for finer or lower bridges.
