Seaview 180° Snorkel Mask Size Chart - How to pick the correct size
There are thousands of positive reviews on Amazon, but you'll also see a few complaints about leaking with most full face snorkel masks. The main reason any mask leaks is that it's not the correct size for the person wearing it. The Seaview 180° now comes in 3 sizes, including a XS for children.
Use the Seaview 180° snorkel mask Sizing Chart below to select the correct size for you.
With your mouth closed, get someone to measure the distance between the bridge of your nose and the bottom of your chin.
Select Size XS if it measures between 3.35" - 3.94" (between 8.5cm - 10 cm) - This size will fit children (but not really young children).
Select Size S/M if it measures greater than 3.94" but less than 4.7" (between 10cm - 12 cm) This size will fit most women and teenagers. It fits slim faces.
Select Size L/XL if it measures more than 4.7" (12 cm and above), This is generally for men.
When you receive your mask, put it on to check that there's no gap between the bottom of the mask and your chin. This is the most common reason for the mask letting in water.
