CHOOSING THE CORRECT FACE MASK SIZE
To determine the correct mask size for your facial structure, we recommend taking exact measurements using the method described below. This is a fairly accurate way to determine your correct size.
Measure below the bridge of your nose to the tip of your chin with a ruler. It may be helpful to have a friend 
assist you. Measure in a straight line up and down. You should be measuring below the bridge of your nose (which is about ½” to 1” below your eye-line).
Please note: For accurate results, do not use a flexible measuring device such as a sewing tape measure or a string. Also do not measure past the tip of your chin.
Match your measurement with the given sizes below to find the correct sizing for you. The chart also provides different facial types to help you find the best fitting mask. Approximate body weights are included as a guide as well.
