The airinum size guide
To find the correct size, we recommend to combine the two measurements below, the weight measurement and the eye-chin distance measurement.
1 WEIGHT MEASUREMENT
The weight measurement is strongly correlated with the length and size of the face, making it a great measurement for mask sizing.
|L||Over 75||Over 165|
|M||50 - 75||110 - 165|
|S||30 - 50||65 - 110|
|XS||12 - 30||26 - 65|
2 EYE - CHIN DISTANCE MEASUREMENT
The eye - chin distance measurement is a very accurate method for estimating the correct mask size.
|L||Over 11.8||Over 4.7|
|M||10.6 - 11.7||4.2 - 4.6|
|S||8.6 - 10.5||3.4 - 4.1|
|XS||Under 8.5||Under 3.3|
If you get diffrent recommendations from the 2 methods, follow the one from the eye - chin distance measurement. If your weight or eye-chin distance is on the borderline, pick the bigger size to ensure a better fit.
