The full comparison, with what each official source says, is in full-face vs traditional snorkel mask.
Questions people ask
How does the quiz decide?
Each answer adds a point or two toward one type, for a reason we show you (a mouthpiece you cannot hold, facial hair, a child, a weaker swimmer). When the gap is small the result says either type can work, because the fit then decides.
Does the quiz say which mask is safest?
No. It points to a type and lists the precautions official sources give. It does not rate products and is not safety training or medical advice.
Are my answers saved?
No. They stay in this page while you use it and disappear when you leave or start again.
What if I wear glasses?
Glasses cannot go under a mask because the arms break the seal. The result adds the prescription options: lenses in a traditional mask or an insert frame in a full-face mask.

"You should be able to achieve an appropriate seal by gently placing the mask on your face and inhaling through your nose. The mask should seal to your face and not fall off even without the mask strap in place. It is not unusual for a small amount of leakage to occur while diving, especially if you have facial hair." Equalizing a mask means "adding air to the space in the mask (by exhaling through your nose)". Read on 2026-10-09.
