Selecting the appropriate size for a full-face snorkelling mask is essential to enhance your snorkeling experience. If the mask is too small, it may cause discomfort by rubbing against the bridge of your nose and squeezing your face. Conversely, if the mask is too large, you are likely to experience consistent leakage.

To determine the correct size that will suit you best, simply measure the distance between the bridge of your nose and the tip of your chin. You can measure this on your own or seek assistance from someone else.

Since different brands have their own unique size standards, it is important to refer to the size chart specific to the mask model you have chosen.
