Faces come in different shapes and sizes. Getting the right fit can be tricky, but is very important. Read on to find out how you can order the right size mask for you.

How your mask fits is imperative to the filters’ ability to actually work. Respirators should be a snug fit, without any gaps for unfiltered air to leak through. Here are 2 ways you can make a pretty good guess or make a more accurate decision at getting the right mask size for you.

1. I’ve got a TAPE MEASURE and I’m not afraid to use it.

  • Suitable for seasoned mask consumers who have purchased one too many a saggy mask, and doesn’t have time for any more nonsense. You get to ditch the next three points and get yourself a mask that is going to fit.
  • Appropriate for all ages
  • High success rate

2. I’ll use my HEIGHT & BODY WEIGHT to guess

  • Appropriate for all ages
  • Varying results
  • Use graphic above to see the metrics


Since body weight can differ hugely between people of all ages, body types, cultures and genders this is by no means a fail-safe way to choose your mask size. The problem with method 2 is that it doesn’t take these following factors into account:

  1. Your weight maybe not be typical, if you have more muscle mass, maybe you weigh heavier than average, but it doesn’t affect your face size.
  2. Body types (Ectomorphic, Endomorphic, and Mesomorphic) are very difficult to factor in. Read more here to see what type you are.
  3. Your height and weight may not correlate at all with face size – this can often be seen in very tall people with ectomorphic body types.

The Cambridge Mask Pro is a fashion-focused pollution mask that comes in a range of patterns and 5 sizes to fit children and adults. There are Extra Small, Small, Medium, Large, and Extra Large. It has an adjustable nose-clip and toggles on the chin part. It means that you may tighten and loosen to get a perfect seal.

So, if you are looking for a mask and need it for yourselves and beloved one, try Cambridge Mask today!

Note: Cambridge Mask has the XS size which is designed for toddlers or very small children. The adjustable apparatus is too big for the mask and therefore we do not produce these at the moment. The XS size does not come with a valve for the same reason. This does not usually create any issues as smaller children do not need to exhale as much air as adults.
