With your mouth closed and teeth together, measure from your lower eyelide, down to your chin. Check your measurement against the sizes below.
If you measure between sizes, choose the larger size.
|2.9-3.4 inch||3.4-3.8 Inch||3.8-4.6 inch||4.6-5.5 inch|
Mask sizes can be estimated using the weight-based method. This method is not as accurate as the measurement-based method and is not recommended for those who wear glasses.
If you weigh between two different size categories, we recommend choosing the larger size.
