JSP Force 10 Mask Size Guide
JSP Force 10 Mask Size Guide with Measurements
The Force 10 mask comes in three sizes: Small, Medium, and Large. Use the following measurements to determine your best fit:
| Size | Face Length (Nose Bridge to Chin) | Face Width (Cheekbone to Cheekbone) | Typical Fit |
| Small | Less than 110 mm | Less than 130 mm | Petite faces |
| Medium | 110–130 mm | 130–150 mm | Average adult faces |
| Large | More than 130 mm | More than 150 mm | Broad or long faces |
How to Measure
Use a flexible tape measure or calipers:
- Face Length: Measure from the bridge of your nose (between the eyes) to the bottom of your chin.
- Face Width: Measure across your face at the widest point of your cheekbones.
Fit Tips
- Medium is the default size and fits most adults.
- Always perform a fit test before use. JSP recommends using their PressToCheck™ filters to verify seal integrity.
- If you're between sizes, choose the larger mask for comfort and seal reliability.
