Tom Wood Ring Size Guide: How to Find Your Size
Tom Wood rings are sized differently from most British jewellery, so it is worth two minutes to get it right before you order. This guide explains how the sizes work, how to measure at home and how to keep your ring looking good.

How Tom Wood ring sizes work
Tom Wood uses European ring sizes. The number is the inner circumference of the ring in millimetres, so a size 54 measures about 54 mm around the inside. The brand's chart runs from 42 to 68; the table below covers 44 to 62.
| Tom Wood size | Inside diameter | UK size | US size |
|---|---|---|---|
| 44 | 14.0 mm | F | 3 |
| 46 | 14.5 mm | G½ | 3⅝ |
| 48 | 15.3 mm | I½ | 4½ |
| 50 | 15.9 mm | K¼ | 5¼ |
| 52 | 16.5 mm | M | 6 |
| 54 | 17.2 mm | N½ | 6¾ |
| 56 | 17.8 mm | P | 7½ |
| 58 | 18.5 mm | Q¾ | 8½ |
| 60 | 19.2 mm | S¼ | 9¼ |
| 62 | 19.8 mm | T½ | 10 |
How to measure at home
If you already own a ring that fits the same finger, measure straight across the inside at its widest point, in millimetres, and match the diameter to the table.
If you do not, wrap a thin strip of paper around the base of the finger, mark where it overlaps and measure the length in millimetres. That figure is your Tom Wood size.
Tom Wood points out that fingers change size with the time of day and the season, and tend to be more swollen in summer, so measure when your hands feel normal. If your knuckle is larger than the place where the ring will sit, choose a measurement between the two. A local jeweller can also measure your finger for you.
Between sizes?
Tom Wood advises the larger size for signet rings and the smaller size for band rings. It also notes that thicker rings, such as its classic signets, often need a slightly larger size than slim bands. In our range, the Knut and Mario (black onyx or white mother of pearl) are slim signets, and the Vintage and ID Band are band rings. Every ring is handmade, so small variations between pieces are normal.
Silver or gold?
Most Tom Wood pieces are 925 sterling silver with white rhodium plating, which gives a strong surface. The gold-coloured pieces we stock are sterling silver with 1 micron of 18k gold plating. Plating wears naturally with use, and a professional jeweller can re-plate it. Tom Wood does not use nickel in its alloys.
How to care for Tom Wood jewellery
- Wipe each piece with a soft cloth after wearing.
- Clean it with warm water and detergent-free soap.
- Store each piece separately in its pouch or box, away from direct sunlight and not in the bathroom.
- Keep it away from chlorine, make-up, soap, perfume and hairspray, and take it off before cleaning, bathing and sleeping.
- Treat stones gently. The black onyx and mother of pearl in the Mario Ring are natural materials, so each one looks slightly different, and they can chip if knocked against a hard surface.
Sterling silver is a soft metal. Small scratches blend together over time and give the ring a softer surface, which Tom Wood treats as normal wear rather than a fault.
