Large 5.82 – 6.14 inch 


To size yourself, it would require a device called a faciometer which is not very common. Medium fits 95% of the population, so if you're an average size person, we would suggest you order a medium. For smaller than average people who weigh 130lb or less, with thin faces, we would suggest a small. For users over 250lb and wide faces, go with large. You will know the size is right if you do a negative pressure test (blocking the inhalation valve and taking a deep breath), and the mask seals tightly to your face.
