How to Find Your Ring Size at Home
Handmade gemstone jewelry feels best when it fits perfectly—snug enough to stay put, comfortable enough to forget you’re wearing it. Here’s a simple, accurate way to measure ring size at home using things you already have.
What you need
- A strip of paper (or string/dental floss)
- A pen
- A ruler (or measuring tape)
- Optional: a ring that already fits
Method A (most accurate): Measure a ring you already own
If you have a ring that fits the intended finger:
- Place the ring on a piece of paper.
- Trace the inside circle.
- Measure the inside diameter (straight across the center) in millimeters.
Use this quick conversion:
16.5 mm → US 6
17.3 mm → US 7
18.1 mm → US 8
If you’re between sizes, go up if:
your fingers swell
it’s a wider band
you want a more relaxed fit
Method B: Paper strip around the finger
This is best if you don’t have a ring to measure.
- Cut a thin strip of paper (about ¼ inch / 6 mm wide).
- Wrap it around the base of your finger (not too tight).
- Mark where the paper overlaps.
- Lay it flat and measure the length in mm — that’s your finger circumference.
Quick conversion (US sizes):
52 mm → 6
54.5 mm → 7
57 mm → 8
Pro tips (these matter):
Measure at the end of the day (fingers are slightly larger).
If your knuckle is bigger than the base, measure both:
it must slide over the knuckle
but not spin once it’s on
Take 3 measurements and use the average.
Fit guidance for handmade gemstone rings
Handmade/beaded rings can feel different than solid metal:
- If the ring is slightly flexible or textured, you may prefer true-to-size.
- If you’re between sizes, choose the size that’s comfortable over the knuckle.
