Finding the Right Diving Mask – Easier Than You Think

At Scubaexpress, we offer a wide selection of diving and snorkeling masks to ensure everyone finds the perfect fit. A well-fitting mask is essential to prevent leaks and discomfort, allowing you to focus on enjoying your dive. The best way to find the right mask is by trying it on properly. Here’s how to do it.

How to Try on a Diving Mask Correctly

Finding the right diving mask is a quick process when you know what to look for. Follow these steps to determine if a mask is suitable for you:

Does the mask seal properly? (Vacuum test)
Can the mask be adjusted easily?
Is the mask the right size?
Does the mask cause pressure points?
Can you equalize pressure comfortably?

Checking for Leaks – The Vacuum Test

The vacuum test is the most effective way to check if a mask seals properly. Follow these steps:

Do not use the mask strap – push the strap forward so it doesn’t interfere.
Press the mask onto your face – ensure there are no hairs under the mask’s sealing lip.
Check positioning – the lower edge should sit between your nose and upper lip, while the upper edge should be above your eyebrows but below the hairline.
Avoid wrinkles – pressing too hard or improper positioning can create leaks.
Inhale slightly through your nose – the mask should stick to your face without holding it in place.

If the mask remains in position while you hold your breath and move your head slightly, it passes the vacuum test.

Considerations for Bearded Divers

The vacuum test may not work well for divers with facial hair. A thick beard or mustache can prevent a proper seal, allowing water to seep into the mask.

Possible solutions:

Shave or trim the beard.
Apply a thin layer of Vaseline over the mustache (this may only work for lighter facial hair).
Choose a mask with a soft, thin sealing lip for a better fit.

Adjusting and Wearing a Diving Mask

Proper Strap Adjustment

A high-quality diving mask should have an adjustable strap. Before putting it on, check how the adjustment mechanism works.

Position the mask correctly – place the strap around your head at eye level.
Adjust the strap evenly – tighten both sides simultaneously to keep the mask centered.
Avoid overtightening – the mask should sit snugly but not too tight. You should be able to pull it slightly away from your face with your fingers.

If you have deep red marks after wearing the mask for a short period, the strap is too tight. The water pressure will naturally help keep the mask in place, so excessive tightening is unnecessary.

Finding the Right Mask Size

Once your mask is sealed and adjusted, check that it fits your face properly. Use a mirror or ask someone to check for you.

At the temples – the mask should sit on the temple, not on the corner of the eye or eyebrow.
On the forehead – the sealing lip should cover the eyebrows but not extend into the hairline.
Around the mouth – the lower edge should sit between the upper lip and nose bridge without pressing too hard.

If the mask fits comfortably without distorting your face, you have found the right size.

Checking for Pressure Points

Before finalizing your choice, ensure the mask frame does not press uncomfortably against your face.

Common pressure points:
- Between the eyebrows (common with two-lens masks).
- On the bridge of the nose (common with single-lens masks).

Wear the mask for a few minutes and press against it slightly to check for discomfort.

Pressure Equalization Test

Equalizing pressure is essential for diving. Make sure you can comfortably pinch your nose while wearing the mask, even with a regulator in your mouth and neoprene gloves on.

If you can easily reach your nose for equalization, the mask is a good fit.
