How do I measure my ring size at home?

Two easy methods: (1) String method — wrap a thin string or strip of paper around the base of your finger, mark where the ends meet, measure the length in millimetres, and match to a ring size chart. (2) Existing ring method — measure the inner diameter of a ring that already fits well, in millimetres, and match to a size chart. Always measure at the end of the day when fingers are at their largest.

What is the most accurate way to measure ring size at home?

The string method is the most accessible home method. For maximum accuracy: measure at the end of the day (fingers are largest then), repeat 2-3 times and use the largest measurement, account for knuckle size by measuring both the base and the knuckle and choosing a size in between if they differ, and remember that thicker bands feel tighter — consider going half a size up for wide bands.

Should I size up or down if I'm between ring sizes?

Always size up if you are between sizes. A ring that is slightly loose is easier to resize than one that is too tight. Your ring should glide over your knuckle without resistance, but feel snug at the base of the finger without sliding off easily.

Does band width affect ring size?

Yes. Thicker bands feel tighter on the finger than thin bands of the same size. If you are choosing a wide band ring, consider going half a size up from your standard measurement. Delicate thin bands sit lighter and may not require this adjustment.

Why does my ring size change throughout the day?

Fingers expand slightly in warm temperatures and after physical activity, and shrink in cold temperatures or in the morning. This is why ring sizing experts recommend measuring at the end of the day — fingers are typically at their largest then — for the most reliable measurement.

Why Rings & I

What actually happens in the studio, and why people choose us over a traditional jeweller.

See the difference →

What you'll need: A thin string (or strip of paper), a pen, and a ruler.

How to do it: Wrap the string around the base of your finger, where the ring will sit. Make sure it's snug but not tight. Mark the point where the ends meet. Then, lay it flat and measure the length in millimetres. This measurement is your finger's circumference. You can then match it to a standard ring size chart.

A small tip: Your ring should glide over your knuckle without feeling loose at the base. If your knuckle is larger, measure both areas and choose a size in between.

The Existing Ring Method: If You Already Own One

If you have a ring that fits perfectly, this method is even easier.

What you'll need: A ruler or measuring tape.

How to do it: Place your ring on a flat surface and measure the inner diameter (the straight line across the inside of the ring). Make sure you're measuring only the inner circle, not the outer edges.

Once you have the diameter in millimetres, refer to a ring size chart to find your match.

Timing Matters More Than You Think

Your fingers aren't the same size all day. They expand slightly in the heat and shrink in colder temperatures. For the most accurate result, measure your finger at the end of the day, when it's at its largest. Avoid measuring right after waking up or when your hands are cold.

Consider the Ring Style

Not all rings feel the same, even in the same size.

● Thicker bands tend to feel tighter. You may want to go half a size up.

● Delicate bands sit lighter and may feel more flexible.

● Stacked rings can change how each ring fits individually.

At Rings & I, where you can explore 10 sizes, 10 shapes, 10 styles, trying prototypes helps you understand this difference before committing to your final piece.

When in Doubt, Measure Twice

Accuracy is everything. Repeat the process two or three times to ensure consistency. If your measurements vary slightly, always choose the larger size—comfort should never be compromised.

A More Thoughtful Way to Find Your Fit

While measuring at home works beautifully, sometimes you want a little more certainty, and a little more experience.

At RINGS & I, we've reimagined how you discover your ring. Instead of guessing, you can try on real prototypes, explore different widths and finishes, and understand how each design feels on your hand.

It's not just about size—it's about how the ring moves with you.

Measuring your ring size at home is simple. But choosing the right ring? That's where it becomes personal.

Because a ring isn't just jewellery. It's something you wear every day, something that becomes part of your story.

So take your time. Measure carefully. And when you're ready, come experience what it feels like to create a ring that's truly yours.

Your ring. Your fit. Your way.
