Method 1. For Hood Masks (e.g., GP-5)
For classic rubber hood-style masks that cover the entire head, you need one vertical measurement:
- Run the tape measure in a closed loop.
- It must pass over the top of the head (crown), cheeks, and chin.
- Round the result to the nearest 0.5 cm.
GP-5 Size Chart:
- Size 0: Up to 63 cm (under 24.8 in)
- Size 1: 63.5 – 65.5 cm (25.0 – 25.8 in)
- Size 2: 66.0 – 68.0 cm (26.0 – 26.8 in)
- Size 3: 68.5 – 70.5 cm (27.0 – 27.8 in)
- Size 4: 71.0 cm and above (over 28.0 in)
Method 2. For Strap Masks (e.g., GP-7)
For modern gas masks with a head harness and adjustable straps, measure the sum of two measurements:
- Vertical circumference: Over the crown, cheeks, and chin.
- Horizontal circumference: Around the forehead (above the eyebrows) and the back of the head.
- Add the two numbers together.
GP-7 Size Chart (based on the sum of both measurements):
- Size 1: Up to 118.5 cm (under 46.6 in)
- Size 2: 119.0 – 121.0 cm (46.8 – 47.6 in)
- Size 3: 121.5 cm and above (over 47.8 in)
How to Check the Fit
- The mask fits tightly.
- There are no gaps between the rubber and your skin.
- The eyepieces are directly in front of your eyes.
- No air escapes from the edges when you exhale.
If you have already measured your head, tell me the result in centimeters or inches and the mask model (if you know it). we can help you find the exact size.
