How to measure ring size is the universal question that hits right before a special purchase—whether you're planning a surprise proposal, buying a gift online, or finally treating yourself.
That moment of doubt, wondering if you'll get it right, can be stressful. I've been there, fumbling with paper strips at midnight before an order deadline. The truth is, finding your ring size at home is straightforward, accurate, and can save you the hassle of returns.
This guide will walk you through every method, provide a clear Indian ring size chart, and share pro tips so you can know your ring size with absolute confidence.
Ring Size Chart (Indian)
This is your master key. Indian jewellery typically uses a numbered system (like Size 9, 10, 11, etc.) based on the inner circumference in millimetres. Use this chart after taking your measurement.
| Indian Size | Circumference (mm) | Diameter (mm) | Approx. US Size |
|---|---|---|---|
| 7 | 47.1 mm | 15.0 mm | 4 |
| 8 | 48.7 mm | 15.5 mm | 4.5 |
| 9 | 50.3 mm | 16.0 mm | 5 |
| 10 | 51.8 mm | 16.5 mm | 5.5 |
| 11 | 53.3 mm | 17.0 mm | 6 |
| 12 | 54.8 mm | 17.5 mm | 6.5 |
| 13 | 56.3 mm | 17.9 mm | 7 |
| 14 | 57.8 mm | 18.4 mm | 7.5 |
| 15 | 59.3 mm | 18.9 mm | 8 |
| 16 | 60.8 mm | 19.4 mm | 8.5 |
| 17 | 62.3 mm | 19.8 mm | 9 |
Pro Tip: Sizes 8-9 are the most common starting points for women in India, and sizes 10-11 for men, but always measure!
Ring Size Chart for Women
While the chart above applies to all, women’s ring size most commonly falls between Indian Size 7 and 9. The average is Size 9. Key considerations:
-
Index & Middle Fingers are often a size larger than the ring finger.
-
Petite bands (<4mm) feel true to size.
-
Statement rings or wide bands (6mm+) often require going up a half or full size for the same comfort.
Ring Size Chart for Men
Men’s fingers are generally larger, with the common range being Indian Size 9 to 12. The average is Size 10.
-
Men’s rings often have wider bands, so factoring in the width is crucial (see tips below).
-
Knuckle size relative to the finger base is a frequent consideration for men.
Ring Size by cm or inches
For absolute precision, measure in millimetres (mm). It’s the global standard for jewellery.
-
Circumference: This is the length around your finger. 50.0 mm = 5.0 cm = ~1.97 inches.
-
Diameter: This is the straight line across the center of the ring. 16.0 mm = 1.6 cm = ~0.63 inches.
Our ring size chart cm/mm above uses these precise measurements to eliminate confusion.
Average Ring Sizes for Women and Men
-
Women's Average: Indian Size 12 (Circumference 54.8 mm, Diameter 17.5 mm)
-
Men's Average: Indian Size 16 (Circumference 60.8 mm, Diameter 19.4 mm)

How To Measure Ring Size With String, Paper & Ruler
This is the most reliable DIY method to check ring size at home. All you need is a piece of non-stretchable string (or a 2cm wide paper strip), a pen, and a ruler with millimetre markings.
Measure Your Ring Size With These Steps: (4 Steps)
Step 1: Wrap
Take the string or paper and wrap it snugly around the base of the finger you want to measure. Ensure it sits where the ring will sit.
Step 2: Mark
Use your pen to mark the point where the string or paper completes one full circle and overlaps.
Step 3: Measure
Lay the string/paper flat. Use your ruler to measure the length from the start to your mark in millimetres (mm). This is your finger's circumference.
Step 4: Match
Take your circumference measurement and find your ring size on the Indian Ring Size Chart above. For example, if you measured 54.8 mm, your Indian ring size is 12.
Pro-Tip: Measure 3-4 times at the end of the day (when fingers are warm and slightly larger) for the most accurate result.
More Ring Sizing Tips
-
Mind the Knuckle: If your knuckle is significantly larger than your finger base, measure the knuckle as well. Choose a size that will slide over it comfortably.
-
Consider Band Width: Rings with a wider band (above 6mm) fit tighter. If choosing a broad ring, consider sizing up by a half or full size.
-
Climate Matters: Fingers shrink in cold weather and swell in heat. Measure in a room-temperature environment.
Which Method is Best for Finding Ring Size?
-
Best for Accuracy at Home: The String & Ruler method described above.
-
Best for Surprises: Measuring the inside diameter of an existing ring that the person already wears on the correct finger.
-
Most Convenient: Using a free printable ring sizer from a reputable jeweller's website (this is a great way to find ring size online).
-
Most Reliable Overall: A professional measurement at a local jeweller. It's often free and takes seconds.
What Happens if I Need Ring Resizing?
Most of our silver rings and other solid metal rings can be resized by a professional jeweller. It involves either stretching the ring (sizing up) or cutting a piece out and soldering it back together (sizing down). There is usually a small cost involved.
What If I Order The Wrong Ring Size?
Don't panic. Reputable online stores (like us at Zalkari.com) have a clear exchange or return policy for such cases. Check the policy before buying. The goal of this guide is to help you avoid this scenario altogether!
Rings That Can't Be Resized
Some ring types are difficult or impossible to resize:
-
Eternity Bands: Rings with stones all around the shank.
-
Tungsten or Titanium Rings: These metals are too hard to resize traditionally.
-
Rings with Intricate, Continuous Patterns: Resizing can ruin the design.
For these styles, getting the size right the first time is essential.
Ring-Size FAQs
What’s the best way to measure your finger size at home?
The string-and-ruler method is the most accessible and accurate home method. For a surprise, measuring an existing ring's inside diameter is best.
Will finger size change depending on when or how I measure it?
Yes! Fingers are smallest in the morning and in cold conditions. They swell slightly by evening, in heat, after salty meals, or during exercise. Always measure at the end of the day for the most reliable fit.
What happens if the ring I order doesn’t fit—can it be resized?
Most solid metal rings (like our 925 silver rings) can be resized by a jeweller. Contact the seller first, as they may offer an exchange or can recommend a local professional for resizing.
What is the easiest way to measure ring size at home?
Using a printed ring sizer you can find online is very easy. The second easiest is the paper strip method. Both are effective ways to know your ring size.
