Size guide
Every piece is made to order and personalized, so it cannot be exchanged for another size once production starts. Two minutes here saves a lot of guessing. If anything is unclear, email support@fondkeep.com with a photo or a measurement and a real person will confirm the size within 24 hours.
Ring size
Our rings use US sizes. If you already own a ring that fits the same finger, measure its inside diameter with a ruler and match it in the table.
| US size | Inside diameter | 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 | 19.0 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 |
| 13 | 22.2 mm | 69.7 mm |
| 14 | 23.0 mm | 72.3 mm |
No ring to measure? Use a strip of paper
- Wrap a thin strip of paper snugly around the base of the finger, where the ring will sit.
- Mark where the paper overlaps and measure that length in millimeters. That is the circumference.
- Pick the closest size in the table. Between two sizes? Choose the larger one, especially for wide bands.
Measure at the end of the day when fingers are warmest, and check that the ring can pass over the knuckle. Buying as a surprise? Borrow a ring they wear on that finger, or ask a friend who knows.
Necklace length
Lengths are the full chain, clasp to clasp. Where it sits depends on the wearer, but these are reliable rules of thumb for most adults.
| Length | Where it sits | Good for |
|---|---|---|
| 16 in (40 cm) | At the base of the neck | Choker look, petite frames |
| 18 in (45 cm) | Just below the collarbone | The most popular choice for pendants |
| 20 in (50 cm) | A little below the collarbone | Layering, larger pendants |
| 22 in (55 cm) | Top of the chest | Men's chains, over sweaters |
| 24 in (60 cm) | Mid chest | Long pendants, taller wearers |
Buying as a gift and unsure? 18 in is the safe choice for women, 22 in for men.
Bracelet size
Measure the wrist just above the wrist bone with a soft tape or a strip of paper, then add room for comfort: about ½ in (1.5 cm) for a comfortable fit, 1 in (2.5 cm) for a loose fit. Adjustable styles cover two sizes.
| Wrist | Bracelet size | Fit |
|---|---|---|
| 5.5 – 6 in (14 – 15 cm) | 6.5 in (16.5 cm) | Petite |
| 6 – 6.5 in (15 – 16.5 cm) | 7 in (18 cm) | Most women |
| 6.5 – 7 in (16.5 – 18 cm) | 7.5 in (19 cm) | Relaxed fit / most men |
| 7 – 7.5 in (18 – 19 cm) | 8 in (20 cm) | Larger wrists |
