💍 How to Check Your Ring Size at Home (No Tools Needed)

Choosing a ring online can feel tricky — especially when you don’t know your ring size. But don’t worry — we’ve got a simple DIY solution.

At Nuit D’or, we want your ring to feel as perfect as it looks. So here’s how to measure your size accurately at home, using things you already have.

✂️ What You’ll Need:

  • A thin strip of paper (or string)

  • A ruler (with millimeter markings)

  • A pen or pencil

  • A little patience 👇

🧠 Step-by-Step: How to Measure

  1. Wrap the paper around the base of your finger (not too tight, not loose).

  2. Mark the point where the paper overlaps.

  3. Lay it flat and measure the length in millimeters.

  4. Use the chart below to match your measurement to your ring size.

  • Most men wear between size 8–11
