Finding the right ring size should be simple. Whether you're choosing a little gift for yourself or a meaningful surprise for someone you love, our ring size guide will help you find a comfortable fit.

At Kynd Co, our rings use US ring sizes. Use the chart below to compare sizes, measure your finger, and shop with confidence.

Measurements are approximate. Actual fit may vary slightly depending on the ring's design and band width.

How to Measure Your Ring Size at Home

Step 1: Wrap

Take a thin strip of paper and gently wrap it around the base of the finger where you'll wear your ring. Make sure it feels comfortable rather than tight.

Step 2: Mark

Mark the point where the paper overlaps. The strip should fit snugly while still being able to slide over your knuckle.

Step 3: Measure

Lay the paper flat against a ruler and measure the marked length in millimeters. This is your finger's approximate circumference.

Step 4: Find Your Size

Compare your measurement with the inner circumference column in our US ring size chart.

For greater accuracy, repeat the measurement two or three times.

How to Measure a Ring You Already Own

Already have a ring that fits perfectly?

1. Choose a ring that fits the same finger.

2. Place it on a flat surface.

3. Measure the inside diameter from one inner edge to the opposite inner edge.

4. Compare the measurement with our size chart.

Measure only the inside of the ring, not the outer edges of the metal band.

What If You're Between Two Sizes?

If your measurement falls between two sizes, the larger size may offer a more comfortable fit.

However, the ideal fit depends on your finger shape, knuckle size, and the width of the ring.

A well-fitting ring should slide over your knuckle with gentle resistance and sit comfortably without spinning excessively.

Tips for Getting the Best Fit

• Measure in the evening. Fingers may be slightly larger later in the day.

• Keep your hands warm. Cold temperatures can temporarily make fingers smaller.

• Avoid measuring immediately after exercise. Temporary swelling may affect your results.

• Consider the band width. Wider bands may feel tighter than delicate, narrow rings.

• Measure the correct finger. Finger sizes can differ between hands.

Buying a Ring as a Gift?

A beautiful ring makes an even more meaningful gift when it fits.

If you're planning a surprise, try borrowing a ring your loved one already wears on the intended finger and measuring its inner diameter.

You can also ask someone close to them for help.

If you're unsure, avoid guessing solely from appearance. A ring that fits one finger may not fit another.

Frequently Asked Questions

Are Kynd Co rings measured in US sizes?

Yes. Our ring size selections follow the US sizing system.

Can I use a UK ring size to choose a US size?

Yes, but UK-to-US conversions are approximate. For the best result, compare the inner diameter or circumference measurements.

What is the most accurate way to find my ring size?

A professional jeweler's measurement is generally the most reliable option. Measuring a ring that already fits well is another useful method.

Should a ring feel tight?

No. It should feel secure and comfortable, with slight resistance when sliding over the knuckle.

Do all ring styles fit the same way?

Not always. Wider bands, unusual shapes, and different settings can affect how a ring feels.

A Little Gift, A Perfect Fit

The right ring is more than a beautiful accessory. It's a reminder of love, connection, and the moments that matter.

Find your size, choose something meaningful, and wear your story.
