Use a Soft Measuring Tape
Use a flexible fabric measuring tape. Do not use a rigid construction-style tape measure.
Find Your Jawvia Size
Choosing the correct size is essential for comfortable, effective vertical jaw support. Use the guide below to measure your head and find the best fit.
How to Measure Your Head
Measure the Circumference
Wrap the tape around the widest part of your head, following the measurement position shown in the image.
Choose Your Size
Keep the tape comfortably snug without pulling it tight, then compare your measurement with the chart.
| Jawvia Model | Medium | Large | Extra Large |
|---|---|---|---|
| Dual Band Plus | 21–22 in 53.3–55.9 cm | 22–23.75 in 55.9–60.3 cm | 23.75–26 in 60.3–66 cm |
| Dual Band Premium | 21–22 in 53.3–55.9 cm | 22–23.75 in 55.9–60.3 cm | 23.75–26 in 60.3–66 cm |
| Dual Band Air Deluxe | 20–22 in 50.8–55.9 cm | 22–24 in 55.9–61 cm | 24–26 in 61–66 cm |
How Should Jawvia Fit?
The cap should sit securely and comfortably without creating pressure points. The blue support band should fit snugly beneath the chin, while the elastic band should provide only a gentle upward lift.
Between Two Sizes?
If your measurement falls directly between two sizes, consider your preferred fit.
Choose the smaller size for a closer fit or the larger size for additional room. Avoid selecting a size that requires excessive band tension to remain secure.
