Our Classic Monocles come in three sizes: 40 mm diameter (Large), 37 mm diameter (Medium), and 34 mm diameter (Small). To find your correct size, please refer to the chart below:
|Taller than 6" (183 cm)||40 mm (Large)
|Between 5' 6" and 6' 0" (167 cm and 183 cm)||37 mm (Medium)|
|Under 5' 6" (167 cm)||34 mm (Small)|
If you're not sure which size to buy, then opt for the smaller monocle. A monocle that is slightly too small will fit much better than a monocle that is slightly too large.
During our development and testing of our monocles we found height to be a convenient, easy, and accurate predictor of monocle fit. Generally, taller people have larger heads and facial features than shorter people. And everyone is different - if you have additional questions about monocle fit please contact us for help.
