Method 1. Use a Strip of Paper

A thin strip of paper is one of the simplest ways to measure your finger.

  1. Cut a narrow strip of paper.
  2. Wrap it comfortably around the base of your finger.
  3. Mark the point where the paper overlaps.
  4. Lay it flat and measure the marked length in millimeters.
  5. Compare the measurement with a ring size chart.

Do not pull the paper too tightly, as this could result in a smaller and more uncomfortable ring size.

Method 2. Measure With a Flexible Tape

A flexible measuring tape allows you to measure your finger’s circumference directly.

  1. Wrap the tape around the base of the intended finger.
  2. Adjust it until it feels snug but comfortable.
  3. Record the measurement where the tape meets.
  4. Compare the result with the circumference column on a ring size chart.

Measure the knuckle as well if it is noticeably wider than the base of your finger.

Method 3. Measure an Existing Ring

If you already have a ring that fits the intended finger correctly, you can use its inner diameter to estimate the size.

  1. Place the ring on a flat surface.
  2. Position a ruler across the widest inside section.
  3. Measure from one inner edge to the opposite inner edge.
  4. Record the diameter in millimeters.
  5. Match the measurement with your ring size chart.

Measure only the empty space inside the ring and do not include the metal edges.

Method 4. Use a Printable Ring Size Chart

A printable ring size chart can help you determine the size of a ring you already own.

  1. Print the chart using the original scale or 100% print setting.
  2. Place a well-fitting ring over the printed circles.
  3. Compare its inner edge with each circle.
  4. Choose the circle that aligns most closely with the inside of the ring.

Incorrect printer scaling can change the circle sizes, so always check the printing instructions before measuring.

Frequently Asked Questions

The easiest method is to wrap a thin strip of paper or a non-stretch string around the base of your finger. Mark where the ends overlap, measure the length in millimeters, and compare it with a reliable ring size chart.

Place a ring that fits comfortably on a flat surface and measure its inside diameter across the widest point. Measure only the empty space inside the ring, without including the metal edges, and compare the result with a ring size chart.

Choose the larger size when your measurement falls between two sizes. A slightly larger ring is generally more comfortable, especially when selecting a wide-band ring.

Yes. Print the chart at 100% or its original scale and place a well-fitting ring over the circles. Select the circle that matches the ring’s inner edge most closely. Incorrect printer scaling can produce an inaccurate result.

Measure both the base of your finger and the widest part of your knuckle when the knuckle is noticeably larger. Choose a size that can pass over the knuckle while still fitting securely at the base.
