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.
