How to Choose the Right
CPAP Mask Size
Why proper mask fitting matters — and how a few minutes with a sizing template can transform your therapy, comfort, and sleep quality.
Choosing the right CPAP mask isn't just about selecting a style — it's about finding the correct size. Even the most advanced CPAP mask won't perform at its best if it doesn't fit properly.
That's why manufacturers like ResMed provide a mask fitting template to help users choose the ideal cushion size before starting therapy. A properly fitted mask improves comfort, reduces air leaks, and helps you get the most out of your CPAP treatment.
Why CPAP mask size is so important.
Your mask forms a seal against your face to deliver continuous airflow all night. If it's too small or too large, that seal can be compromised.
What is a CPAP mask fitting template?
A simple sizing guide, provided by the manufacturer, that takes the guesswork out of choosing your cushion size.
You place the template against your face — usually around the nose — and compare your facial measurements with the sizing guide to determine the correct cushion size. Depending on the mask model, sizes typically include Small, Medium, and Large.
Using the fitting template helps eliminate guesswork and increases the likelihood of choosing the correct mask size on your first attempt.
