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.
- Use a weight scale to find out your weight
- Compare the measurement to the table below
| Recommended Size | KG | LB |
|---|---|---|
| L | Over 70 | Over 155 |
| M | 45-70 | 100-155 |
| S | 25-45 | 55-100 |
| XS | 12-25 | 26-55 |
2 EYE - CHIN DISTANCE MEASUREMENT
The eye - chin distance measurement is a very accurate method for estimating the correct mask size.
- Use a ruler and measure the vertical distance between your lower eyelid and you chin
- Note that this is easiest to do in front of a mirror or with the help of a friend.
- Compare the measurement to the table in the picture below
| Recommended Size | CM | IN |
|---|---|---|
| L | Over 11.4 | Over 4.5 |
| M | 10.2 - 11.3 | 4.0 - 4.4 |
| S | 8.2 - 10.1 | 3.2 - 3.9 |
| XS | Under 8.1 | Under 3.1 |
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.
