Size Guide
Size guide
All sizing on TripTrike is US. If you're between sizes, go up — a ring that spins is easier to live with than one you can't get off.
Rings
Measure a ring you already own. Lay it flat and measure the inside diameter across the middle, in millimetres.
| US size | Inside diameter | Inside circumference |
|---|---|---|
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
| 11 | 20.6 mm | 64.6 mm |
| 12 | 21.4 mm | 67.2 mm |
No ring to measure? Wrap a strip of paper around the base of the finger, mark where it overlaps, lay it flat and measure the length in millimetres — that's the circumference. Measure at the end of the day when fingers are at their largest, and make sure the strip passes over the knuckle.
Necklaces
| Length | Where it sits |
|---|---|
| 14" / 35 cm | Choker — around the base of the neck |
| 16" / 40 cm | At the collarbone |
| 18" / 45 cm | Just below the collarbone — the most common length |
| 20" / 50 cm | A few centimetres above the neckline |
| 24" / 60 cm | Mid-chest — good over a sweater |
Most of our chains include a 5 cm extender, so one necklace covers two of these lengths.
Bracelets & anklets
Measure around the wrist just below the wrist bone with a tape or a strip of paper, then add 1.5 cm for a comfortable fit or 2.5 cm for a loose one. Typical women's bracelet: 17–19 cm. Typical men's: 20–22 cm. Anklets: measure the ankle bone and add 2 cm.
Watches
Case size is the dial diameter excluding the crown, and it is listed on every watch product page.
| Case size | Suits a wrist of |
|---|---|
| 24–30 mm | 13–15 cm — small, delicate look |
| 32–36 mm | 14–17 cm — classic women's proportion |
| 38–42 mm | 16–19 cm — unisex and most men's dress watches |
| 44–48 mm | 19 cm and up — sport and chronograph styles |
Strap length. Steel bracelets ship at their full length with removable links; a jeweller or a $6 link-removal tool adjusts them in a few minutes. Leather and silicone straps have fixed holes — the adjustable range is listed on each product page.
