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

Modified on Thu, 7 Mar at 4:18 PM

To find the correct size for the Urban 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	10-25 kg	22-55 lb
S	25-55 kg	55-120 lb
M	55-80 kg	120-175 lb
L	Over 80 kg	Over 175 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. It's also helpful to use a book.

3. Compare your measurement to the table below to find your recommended size.

Recommended Size	Eye-Chin Distance (cm)	Eye-Chin Distance (inches)
XS	Less than 8.5 cm	Less than 3.3 IN
S	8.6-10.5 cm	3.4-4.1 IN
M	10.6-12.0 cm	4.2-4.7 IN
L	Over 12.1 cm	Over 4.8 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.
