Ring Size Guide

How to Measure Your Ring Size at Home

You do not need to visit a jeweler to find your ring size. The paper strip method below is accurate, free, and takes less than two minutes.

Method 1: Paper Strip (Most Accurate)

1. Cut a thin strip of paper about 6 inches long and ½ inch wide.
2. Wrap it snugly around the base of the finger you plan to wear the ring on — not too tight, not loose.
3. Mark the point where the paper overlaps with a pen or pencil.
4. Lay the strip flat and measure the marked length in millimeters.
5. Compare to the size chart below to find your US ring size.

Method 2: Existing Ring

If you have a ring that fits the correct finger, place it flat on a ruler and measure the inside diameter (the distance across the hollow center) in millimeters. Then use the diameter column in the chart below.

Ring Sizing Tips

When to Measure

• Best time: Late afternoon or evening — fingers are at their natural largest size.
• Avoid: First thing in the morning (fingers are smaller), after exercise, or in very cold weather.
• Room temperature: Fingers shrink noticeably in cold — always measure in a warm room.

If You Are Between Sizes

When your measurement falls between two ring sizes, the general rule is:

• For narrow bands (under 4mm): choose the smaller size — narrow bands slide off more easily.
• For wide bands (6mm or wider): choose the larger size — wide bands fit tighter and are harder to remove.
• For engagement rings and comfort-fit styles: size up for day-to-day comfort.

Ordering an Engagement Ring as a Surprise

If you are ordering a surprise engagement ring, here are ways to estimate size without spoiling the proposal:

• Borrow a ring your partner already wears on their ring finger and trace the inside on paper.
• Ask a close friend or family member who might know.
• Order a size 6 or 7 (the two most common women's sizes) — most rings can be resized 1–2 sizes after the proposal.

Rings That Cannot Be Resized

• Full eternity bands with stones all the way around
• Tungsten carbide rings (too hard to cut)
• Titanium rings
• Rings with elaborate patterns running the length of the band
• Some tension-set rings
