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.
Instruction:
- Use a weight scale to find out your weight
- Compare the measurement to the table
| Recommended Size | Weight (KG) |
|---|---|
| L | Over 75 kg. |
| M | 50 – 75 kg. |
| S | 30 – 50 kg. |
| XS | 12 – 30 kg. |
2 EYE – CHIN DISTANCE MEASUREMENT
The eye – chin distance measurement is a very accurate method for estimating the correct mask size.
Instruction:
- 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

If you get different 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 one to ensure a better fit.
