Step-by-Step: How to Measure Your Ring Size at Home
✦ Method 1: Using a Ring You Already Own
- Select a ring that fits the intended finger.
- Use a precise tool—like a caliper or ruler—to measure the inside diameter across the widest point.
- Compare this number against the chart below to determine the US ring size.
✦ Method 2: Wrapping with a String or Paper Strip
- Take a thin strip of paper or string.
- Wrap it snugly (but not tightly) around the base of your finger.
- Mark where the ends meet.
- Measure the circumference in millimeters, then use the chart below to find your ring size.

Measurement Tips — Accuracy Matters
- Measure at the end of the day, when fingers are naturally more enlarged.
- Don’t measure on cold hands—cold can shrink finger size temporarily.
- For half-sizes, consider rounding up for comfort.
- Avoid too-tight wraps—you want a ring that’s secure but easy to remove.
- Double-check with a caliper if possible; millimeter precision makes a difference
