How to Measure Ring Size: A Complete Guide

 

Finding the perfect ring size is essential for comfort and ensuring your ring fits securely. Whether you're measuring for yourself or as a surprise for someone else, this guide will help you determine the correct size using Australian sizing standards.

Method 1: Measure an Existing Ring

  1. Find a Well-Fitting Ring: Use a ring that fits comfortably on the intended finger.

  2. Measure the Inside Diameter:

    • Place the ring on a ruler.

    • Measure the diameter (in millimetres) across the widest inside part of the ring.

  3. Compare to an Australian Ring Size Chart: Match the diameter measurement to a standard size chart to find the corresponding ring size, see below.

Diameter (mm) Australian Size
14.5 F
15.7 J
16.5 L
17.3 N
18.1 P
19.1 R

(Note: These are common sizes. Refer to a full chart for more options.)

Method 2: Measure Your Finger

  1. Use String or Paper:

    • Wrap a thin strip of paper or string around the base of the finger. Be careful not to use a string that will stretch.

    • Mark the point where it overlaps.

    • Measure the length of the string/paper in millimetres.

  2. Convert to a Ring Size: Use the following conversion chart:

Circumference (mm) Australian Size
44.2 F
48.7 J
51.2 L
54.4 N
57.0 P
60.0 R

(Tip: Measure at the end of the day when your fingers are at their largest.)

Tips for Accurate Measurement

  • Consider Finger Swelling: Fingers can change size throughout the day and in different temperatures.

  • Measure Multiple Times: Take measurements a few times to ensure accuracy.

  • Account for Ring Width: Wider bands may require a slightly larger size for comfort.

Frequently Asked Questions

1. Can I measure a ring size without the person knowing?

  • Yes! Borrow a ring they already wear on the intended finger and measure it.

2. What if I’m between sizes?

  • Choose the larger size to ensure comfort, it's also easier to reduce the size of a ring than enlarge the size of a ring. 

3. Are Australian ring sizes the same as US sizes?

  • No, Australian sizes differ. For example, an Australian size J is equivalent to a US size 5.
