Is half mask size important?

Face Size and Shape

Face size and shape are important considerations when selecting RPE. The mask must fit the wearer’s facial features to create a seal and provide protection. Respirators are available in a range of sizes to fit different facial dimensions. To ensure a good fit, face shape and size must be considered and, if possible, measured prior to selection.

Respirator sizes are based on dimensions given in international standard ISO 16976-2, Anthropometrics. Five headform sizes are described in the standard: Small, Short-Wide, Medium, Long-Narrow, and Large.

The five headforms are derived from measured facial dimensions of human test subjects and are used for designing respiratory protective equipment as well as helping with selection. Respirators are designed to fit specific size designations and are tested on the relevant headform size.
