Choosing a scuba or snorkel mask that actually fits
This guide answers the common question of how to choose a scuba or snorkel mask that fits properly, based on decades of real-world diving experience.
This guidance comes from Freddy, founder of Leviathan Scuba, drawing on decades of personal diving experience and years of fitting divers in real-world conditions — not showroom theory.
The approach is simple: fit first, marketing last.

Short Version: Core Mask Fit Principles
This shorter version covers the most important mask-fit principles for divers who want to avoid common mistakes without investing as much time.
~15 minutes • Practical guidance distilled from years of fitting experience.
Why Proper Mask Fit Matters
- Leaks are almost always caused by fit, not mask quality
- Face shape matters more than brand or price
- A comfortable mask improves confidence and breathing underwater
- Most features are meaningless if the seal isn’t right
A well-fitting mask seals gently without excessive strap tension.
Where to Buy & Get Fitted
Mask fit is personal. When possible, in-person fitting is recommended so you can confirm comfort, seal, and visibility before committing.
Divers are welcome to visit Coral Key Scuba in Arvada, Colorado for in-person mask fitting. Depending on the day, you may even have the opportunity to be fitted by Freddy himself.
Coral Key Scuba’s staff is trained using the same fit-first principles Freddy teaches, ensuring consistent care and guidance even when he is not on the floor.
For those who prefer to shop online, LeviathanScuba.com carries masks selected using these same real-world fitting standards.
