3. How to Measure at Home — Step by Step

  1. Choose the right time: measure in the afternoon or evening — fingers are at their daily largest.
  2. Temperature: measure at room temperature. Cold fingers can be up to 1 full size smaller.
  3. Choose the right hand and finger: always measure the specific hand and finger the ring will be worn on.
  4. Wrap a paper strip (1cm × 15cm) snugly around the base of the target finger. No gap, no compression.
  5. Mark the overlap with a pen exactly where the strip first crosses itself.
  6. Measure in mm from the end to the mark — this is your finger circumference.
  7. Match to the chart: find your circumference in the table. If between two sizes, choose the LARGER.
  8. Also measure the knuckle — if noticeably wider, use that for closed-band rings.

4. Wide Band Adjustment for Men’s Rings

Men’s wedding bands and signet rings are typically 6–10mm wide. Wide bands require a larger size than a narrow ring.

Band WidthSize Adjustment Needed
Under 4mmNo adjustment
4–6mmAdd 0.25 size
6–8mmAdd 0.5 size
8–12mmAdd 0.5 to 1.0 size
Over 12mmAdd 1.0 size minimum

5. Tungsten, Titanium & Cobalt Rings

  • These materials cannot be resized by any jeweller.
  • Measure at least twice on different days and at different times.
  • If between two sizes, always order the larger.
  • Consider ordering a plastic trial ring before committing to the final piece.

6. Secretly Finding His Ring Size

  • Method 1 (most accurate): Borrow a ring he wears on the target finger. Measure the inner diameter and match to the chart.
  • Method 2: Ask his friends or family.
  • Method 3: Use the printable circle guide while he’s asleep (accurate to ±0.5–1 size).
  • Rough estimate from gloves: Medium ≈ US 9–10 · Large ≈ US 10–11 · XL ≈ US 11–13.
  • When guessing between two sizes: always choose the LARGER.
