Mask Measurement Chart


Below is a general guide based on body weight (note that facial measurements are more accurate for ensuring correct fit).

    • LARGE - 5 inches (12.7 cm)  -We recommend this size for male adults
    • MEDIUM - 4.5 inches (11.4 cm) - Recommended for female adult
    • SMALL - 4 inches (10.2 cm)  - Recommended for people with smaller faces

*You can find a weight specific chart below


We recommend taking exact measurements using the method described below to determine the correct mask size for your facial structure

  1. Measure from the center line of your face at your mouth to at least 1 inch (2.5 cm) past the outside corner of your mouth (you might want to ask a friend to assist you). The outer edge of the mask should sit against your face at 1 to 1.5 inches (2.5 to 3.8 cm) outside the corner of your mouth
  2. Double the measurement you have taken and match to the best fit from the below:
  • LARGE - 5 inches (12.7 cm)        180+
  • MEDIUM - 4.5 inches (11.4 cm)   150lbs to 180lbs
  • SMALL - 4 inches (10.2 cm)        100lbs to 145lbs

Sleeve sizing is designed to match your chosen mask size, i.e. Large (L) sleeve suits a Large mask.
