- Cut a thin strip of paper or grab a piece of string.
- Wrap it around your finger’s base, marking where the ends overlap.
- Lay it flat and measure the length with a ruler (in millimeters).
- Match your measurement to our ring size chart (see below).
Important: String can stretch, so don’t pull too tight while measuring.
Step 2: Consider These Fit Factors
Your ring size isn’t always the same - it can change based on different conditions. Keep these factors in mind for the best fit:
- Time of Day Matters – Fingers are smaller in the morning and larger in the evening because of natural swelling. Measure in the evening for the most comfortable fit.
- Temperature Changes Everything – Cold fingers shrink, warm fingers expand. Measure at room temperature for the best accuracy.
- Knuckles Can Affect Fit – If your knuckles are large, go half a size up so the ring slides on easily but still fits securely.
- Band Width Plays a Role – Wider bands feel tighter, so you might need to go up half a size for a thick ring.
Pro Tip: If you’re between sizes, it’s usually best to size up - a jeweler can always adjust the fit if needed.
Step 3: Match Your Size to the Chart
Now that you’ve measured your finger, use our Ring Size Chart to find your perfect match.
