Size Guide For Structural Band
Archive Calibration GuideAura Brilliant archives feature a precision Comfort-Fit domed interior. This allows the monolithic metal to slide smoothly and adapt to the natural volumetric fluctuations of your tissue.
The Tension Rule: Flesh compresses; tungsten does not. For absolute precision, measure the inner diameter of an existing ring that fits perfectly and match it below.
| US Size | Diameter (mm) | Circumference |
|---|---|---|
| 7 | 17.3 | 54.4 |
| 8 | 18.1 | 56.9 |
| 9 | 18.9 | 59.5 |
| 10 | 19.8 | 62.1 |
| 11 | 20.6 | 64.6 |
| 12 | 21.4 | 67.2 |
| 13 | 22.2 | 69.7 |

Paper does not stretch. Ensure the strip is pulled tightly across the knuckle to simulate metal compression, or it will read 1 size too large.
The 8mm Profile Logic: Given our substantial width, if your diameter measurement falls strictly between two sizes, we recommend selecting the next whole size up.
Complimentary Archive Exchange We engineer resilience, not friction. Should your initial calibration be less than absolute, we provide a complimentary re-calibration piece, once per acquisition — no return of the original is required.
Calibrate this screen against an object of known dimension, then read your size directly off the glass.
Hold any bank card flat against the screen, short edge across, and drag until the outline matches its edges exactly. Every bank card measures 53.98 × 85.60 mm — ISO/IEC 7810, without exception. Use a US quarter instead →

Lay the ring flat on the screen. The circle should sit exactly inside the band, its outline just disappearing beneath the metal. Flesh compresses; tungsten does not — on an 8 mm profile, if you fall between two sizes, take the larger.
