How do I choose the correct size for Lite Air Mask?

Modified on Thu, 1 Feb at 6:51 PM

To determine the correct size for the Lite Air Mask, we recommend combining the two measurements below: the Weight Measurement and the Eye-Chin Distance Measurement.

WEIGHT MEASUREMENT

The weight measurement is strongly correlated with the length and size of the face, making it a great measurement for mask sizing.

Instructions:

1. Use a weight scale to find your weight

2. Compare your weight to the table below to find your size

Recommended Size	Weight (KG)	Weight (LB)
XS	12-20 kg	26-44 lb
S	20-40 kg	44-88 lb
M	40-70 kg	88-154 lb
L	Over 70 kg	Over 154 lb

EYE-CHIN DISTANCE MEASUREMENT

The eye-chin distance measurement is a very accurate method for getting the correct mask size.

Instructions:

1. Use a ruler and measure the vertical distance between your lower eyelid and your chin

2. It can be helpful to do this in front of a mirror or with the help of a friend.

3. Compare your measurement to the table below.

Recommended Size	Eye-Chin Distance (cm)	Eye-Chin Distance (inches)
XS	Less than 8.1 cm	Less than 3.1 IN
S	8.2-10.1 cm	3.2-3.9 IN
M	10.2-11.3 cm	4.0-4.4 IN
L	Over 11.4 cm	Over 4.5 IN

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.
