How to Know If a Scuba Mask Fits Properly? Things to Look Out For

There are many different scuba masks out there, and as a scuba diver or snorkeler, you need to find one that fits your face properly. The last thing you want is to dive in the water and find out 10 meters down that it's letting water in!

Scuba masks come in various shapes and sizes. This means that there are no one-size-fits-all options. You need to keep multiple factors in mind to ensure your mask fits in the way it should. We've created a step-by-step process on what you should look into and what you should avoid.

How to Find a Properly Fitting Scuba Mask

To find a properly fitting mask, there are some specific measures you'll need to take. Here is what you need to do:

1. Consider Your Facial Structure

First things first, when you get a scuba diving mask, you need to take a good look in the mirror. Do you have a narrow face, or is it more on the wider side? Are your eyes wide apart, or are they closer together? Is your nose on the smaller side or more prominent?

These things need to be adequately considered because no one's face shape is the same. For example, if you have a narrow face, a mask with a broader frame may let the water go in. This is why it's necessary to keep every aspect of your face in mind before going to the store. Consider everything, from the width of your face to how much space you have between your lips and nose.

2. Try On Masks Based on Your Face Shape

Once you've taken note of your facial structure, you need to try on as many masks as possible. Rather than focusing on masks with fancy features, you should try out something that appears fitting for your face.

Put the mask over the face, placing the straps at the top or front of the mask. You won't want to put the strap over the head just yet; you need to determine whether the mask is too wide or too narrow for where your eyes sit. Every aspect of the fit must be considered here.

3. Test the Suction of the Mask

If the mask seems to be a good fit on the first try, you may want to move on to the next step: the suction test. At this point, the straps still need to be away from your head, but as you put the mask on, press it slightly. Once you do that, inhale through your nose and remove your hands from the mask.

Your mask should suction to your face without you needing to inhale again. A properly fitted scuba or snorkel mask should also stay on your face, regardless of your facial gestures. Try moving the muscles of your face a bit – for example, try smiling. Even seals on good masks can break when you smile, so you've got yourself a good one if it holds.

4. Put the Mask on with the Straps

Once you are satisfied with the suction action, it's time to put the straps on. It will complete the suction process of the mask. Bear in mind that the straps need to go around the head, not rest on your ears. If you do that, it can become painful.

If you need to pull on the strap or you end up getting red marks, then the mask is too small. You might want to consider getting a mask with adjustable straps.

5. Test the Scuba Mask in Water

If possible, you might want to try the scuba mask in the water – a pool would be ideal, but even a big bowl of water is fine. If you can't take the mask home or return it, check if they have a pool. Maybe you can test it before buying it.

Why Your Scuba Mask May Not Be a Good Fit

Sometimes, the mask may not fit properly. Here are the usual culprits:

1. There Are Obstructions

Certain obstructions may prevent an otherwise good-fitting mask from staying on your face. This usually involves things such as hair (typically facial hair, especially mustaches), a folded mask skirt, or any other things that may prevent contact with your face. Ideally, you may want to get a shave before going to buy a mask.

2. The Straps Are Too Tight

Many people think that if you over-tighten the mask, it will stay on better – but in fact, it's the suction that keeps it on. By pulling the straps too tight, you pull on the seals and disrupt the tension. Keep a regular tightness on the straps.

3. The Size May Be Wrong for Your Face Shape

If it's neither of the above and your scuba mask is still letting water in, you chose the wrong size. You should consider going through the fitting process again with other masks.

The Bottom Line

A scuba mask that fits properly will keep the water out of your eyes and nose. This will make your underwater experience more fulfilling, so choosing the best mask the first time around is worth it. It might take a while to get the right fit, but every little detail will keep you breathing and seeing perfectly underwater.
