MICHAEL / Frame Fit & Style
Eyeglass Frame Size Calculator & 17-Model Millimetre Matcher
Enter the three millimetre numbers stamped inside your current glasses (lens width × bridge width × temple length) to find your closest physical fit across all 17 MICHAEL EM frames.
How the 3-number millimetre matching system works
Almost every pair of prescription eyeglasses has three millimetre numbers printed inside the temple arm—for example, 49 □ 22 - 145. Here is how to match those numbers against the 17 models in the MICHAEL EM collection:
- 1. Lens Width (40–52 mm in EM): Match within ±2 mm of your favourite pair so the frames align naturally with your cheekbones and pupillary distance (PD).
- 2. Bridge Width (22–32 mm in EM): Match within ±1–2 mm. A bridge that matches your nasal contour prevents sliding and eliminates red pinch marks.
- 3. Temple Length (135–148 mm in EM): Match within ±3–5 mm so the temple bend rests securely behind your ear.
