The easiest way to find your mask size is to measure the width and length of your face with measuring tape. To measure the width you will need to measure from ear to ear, running the tape just beneath the nose and above the lip. To measure the height grab the same measuring tape and measure from the the middle point between the bridge of your nose and tip of your nose and run it down your face to about 1cm-1.5cm under your chin.
