Ring Size Guide for
A Perfect, Lasting Fit

An accurate size from the start avoids resizing later — especially important for gemstone rings, where the setting makes alterations difficult. Two simple ways to measure, below.
Start Measuring
Before You Measure
Know Measurement Terms
Two terms come up throughout this guide — Circumference and Diameter.

Circumference

The distance around your finger. This is what you get from the paper-strip or string method — wrap it around the base of your finger, mark the overlap, then measure the length.

Diameter

The distance straight across the inside of a ring. This is what you get by measuring a ring that already fits well, from one inner edge to the other through the centre.

Method 1
The Hands-On Approach
All you need is a strip of paper or non-stretchable string, a pen, and a ruler marked in millimetres.
1
Wrap It Around
Wrap the paper or string around the base of your finger, where the ring will sit. Keep it snug — not too tight, not too loose.
2
Mark the Overlap
Mark the point where the string or paper overlaps itself with a pen.
3
Lay It Flat & Measure
Lay the string or paper flat against the ruler and measure the length from the start to your mark, in millimetres.
4
Match to the Chart
Find your measurement in the Circumference (mm) column of the size chart below to get your ring size.

Method 2
Using an Existing Ring
Quicker if you already have a ring that fits the finger you're sizing for — no physical measurement of your finger needed.
1
Lay It Flat
Place the ring on a flat surface, right side up, with the band resting flat rather than tilted.
2
Position the Ruler
Slide a ruler underneath so its inner edge lines up with the "0" mark, with the ring centred over the markings.
3
Measure Straight Across
Measure the distance across the inner circle, from one inside edge to the other, through the centre point — not the outer edge of the band.

Common Questions
Ring Sizing, Answered
What if my finger size changes between seasons?

Fingers can swell slightly in heat and shrink in cold. If you're between two sizes, we generally recommend sizing up slightly and going with the adjustable option if you're unsure — it's easier to adjust a slightly loose ring than a tight one.

Can I resize a gemstone ring later if needed?

It's possible, but more difficult and riskier than with a plain metal band, since the gemstone setting can be disturbed during resizing. Getting an accurate size upfront is strongly recommended.

Which finger should I measure for an astrological ring?

This depends on the specific gemstone and the finger prescribed for its ruling planet — our Vedic experts can guide you on the correct finger as part of your consultation.

Do you offer a ring sizer tool?

Yes — if you're not confident measuring at home, contact us and we'll send a free ring sizer tool to your address before your order is finalised.

What if I don't know my size and can't wait for a sizer tool?

Choose the adjustable sizing option at checkout — we'll fit the ring based on your finger measurements and gender, so you can order with confidence even without an exact size.

What if my knuckle is wider than the base of my finger?

Measure both the base of your finger and the knuckle, then let us know both figures — we can adjust the setting slightly so the ring slides over comfortably while still sitting snugly at the base.

Does temperature affect my measurement?

Yes — fingers are typically smaller in the morning or in cold weather, and swell slightly in heat or later in the day. For the most reliable reading, measure at room temperature, in the evening, when your hands are at a normal size.

What's the difference between Indian, US and UK ring sizes?

They're simply different numbering systems for the same physical measurement — an Indian size 14, for instance, corresponds to a US size 7 and a UK size N. Use the size chart above to convert between them using your circumference or diameter measurement.

Is the ring sizer tool free?

Yes — if you contact us for a ring sizer tool, we'll send it to your doorstep free of charge, with no obligation to purchase.
