Wig Size Guide
The Signature 613
The Signature 613 is built on an average cap with adjustable elastic straps that fit most head sizes. Use this guide to confirm your measurements before ordering.
Cap Size Chart
| Size | Circumference | Front to Nape | Ear to Ear |
|---|---|---|---|
| Small | 21.5" (55cm) | 13.5" | 11.5" |
| Medium — default | 22.5" (57cm) | 14.5" | 12.5" |
| Large | 23.5" (60cm) | 15.5" | 13.5" |
The Signature 613 ships in Medium (22.5" / 57cm) by default. The adjustable elastic straps accommodate a range of approximately 21.5"–23.5" (55–60cm). If your circumference measurement falls within this range, the standard cap will fit without modification.
How to Measure Your Head
Use a soft fabric tape measure. Do not use a rigid measuring tape — it will not conform to the shape of your head and will give an inaccurate reading.
- Circumference: Start at your natural hairline at the centre of your forehead. Wrap the tape around the full perimeter of your head — across the forehead, behind the ears, across the nape — and back to your starting point. This is your primary measurement.
- Front to Nape: Place the tape at your natural hairline at the centre of your forehead. Run it over the top of your head down to the nape of your neck. Keep the tape centred as you measure.
- Ear to Ear: Place the tape at the top of one ear, run it across the top of your head to the top of the other ear.
Measure twice and use the larger reading if your two measurements differ slightly.
Finding Your Size
Match your circumference measurement to the chart above. The circumference is the most important measurement for cap fit.
Between sizes: If your circumference falls between Small and Medium — for example, 22" — the Medium cap with the elastic straps adjusted inward will provide the most secure fit. The straps reduce the effective cap circumference by approximately 1".
Above 23.5" (60cm): Contact us at support@nobletress.com with your measurements before ordering. We will advise on fit and available options.
How the Adjustable Straps Work
The Signature 613 features two adjustable elastic straps at the nape. Each strap has multiple hook positions — moving the hook inward tightens the cap, moving it outward loosens it.
Most customers adjust the straps once at first wear and do not need to adjust again. The four precision-placed combs hold the wig in position during wear — the straps provide the foundational fit.
