I used to think measuring my face for glasses required special tools or a professional. Turns out, all I needed was a ruler and a mirror. Here's exactly how to measure face for glasses the way I do it.
1. Face Width
Stand in front of the mirror and measure from the widest point of one cheekbone to the other. For me, this is 145mm. This tells you the maximum frame width you should consider.
2. Bridge Width
Measure across the bridge of your nose at its narrowest point, usually right between your eyes. Mine is 18mm. This is crucial for comfort - too narrow and glasses pinch, too wide and they slide.
3. Temple Length
Measure from your temple (beside your eye) to just behind your ear where glasses would rest. I need 145mm. This ensures the arms are long enough without being too long.
Once I had these numbers, shopping became easy:
If you already have glasses that fit well, just check the numbers printed inside the temple arm. Those are your ideal measurements. No need to measure your face at all.
Measuring takes less than five minutes but saves hours of frustration with ill-fitting glasses. It's absolutely worth doing before you shop.
