Customer Service

ResMed is happy to offer sizing templates for many of our masks. Click your mask below to open a PDF file of the fitting template. Please note the following when using these templates:

- Read the directions on the template carefully before cutting and using them.

- Mask sizing templates should be used to aid in the fitting of masks. The use of these templates is not intended to replace the advice of a medical professional, sleep technician or equipment supplier.

- Altering the size or dimensions of the original PDFs in any way may compromise the quality and accuracy of these template printouts. To avoid this problem, ensure you are printing at the actual size by turning off all page scaling in your printer settings. You may also refer to the ruler within the printout to ensure the printout is the accurate size.

What's the correct way to fit a mask?

There are many useful resources to help you achieve a good mask fit.Your mask user guide is a good starting point as it contains complete fitting instructions specific to your mask. There are also a number of helpful ResMed mask-fitting videos available online. Your sleep physician or clinic may also be able to you fit your mask properly. Additionally, we are pleased to offer private Mask Fitting appointments at our two ResMed Centres for Healthy Sleep. In general, these factors can affect your fit:

Size

If you can only get a good seal by tightening the mask until it’s uncomfortable, then you may have the wrong size of mask. Please note that sizing across different masks is not always the same. Talk to your equipment supplier or sleep specialist to be re-fitted with the correct size of mask.

Position

The fit of a mask depends a great deal on your position: a mask that fits well when you're sitting up might not fit so well when you're lying down. This is because our facial muscles change when we lie down and relax even further when we're asleep. It's always best to fit the mask while you're in your sleeping position: whether you sleep in a bed with no pillows or in a recliner, you should fit your mask in your usual sleeping position.

Headgear

Your mask should be as loose as possible while still creating a seal. If you feel your headgear strap is too loose or too tight, you should try re-adjusting it, or replacing your headgear if it is old or worn out.

How should you choose a mask?

If your mask is properly fitted but still feels uncomfortable, you might need another type of mask. ResMed offers full face masks, nasal masks, and nasal pillows; you’ll find that some mask types and models may suit you better than others.
