**Is this frame the right size for me?**

Try on any pair of glasses or sunglasses that already fit you well to see if this frame will suit you.

1. Measure the actual lens width and bridge width on your glasses using a ruler. The lens width should be around 40-60 mm and the bridge width should be around 12-24 mm.

2. Multiply the lens width by 2, and add this number and the bridge width together. This should give you a number between 100-140 mm.

3. For the best fit, we suggest choosing a frame that is within 5 mm of this number. Enter your number between 100-140 mm below to more accurately see if this frame is the right size for you.
