How to Measure

Find Your Ring Size at Home

Method One

The String Method

This method uses a length of string, ribbon, or a thin strip of paper to measure the circumference of your finger.

Cut a piece of string or a thin strip of paper approximately 10 cm (4 inches) long.
Wrap it snugly around the base of the finger you intend to wear the ring on. It should be comfortable. Not too tight, not too loose.
Mark the point where the string overlaps with a pen or fine marker.
Lay the string flat against a ruler and measure the length in millimetres from the end to your mark.
Match your measurement to the 'Circumference' column in our size chart above to find your ring size.

Method Two

The Existing Ring Method

If you already own a ring that fits well or are measuring for a surprise gift, this method uses the interior diameter of an existing ring.

Select a ring that fits comfortably on the intended finger. Ensure it is a similar width to the ring you wish to order, as wider bands typically require a slightly larger size.
Place the ring on a flat surface. Using a ruler with millimetre markings, measure the inside diameter of the ring — the distance from one inner edge to the opposite inner edge.
Match your measurement to the 'Diameter' column in our size chart above. If your measurement falls between two sizes, we recommend selecting the larger size.

Expert Advice

Sizing Tips

Our artisans have decades of experience crafting rings that feel as beautiful as they look. These tips will help ensure the perfect fit.

Measure at the Right Time

Fingers change size throughout the day. For the most accurate result, measure in the late afternoon or evening when your fingers are at their largest. Take into consideration that measuring your hands when they are cold will give a smaller size, as fingers tend to shrink.

Consider the Band Width

Wider bands (6mm and above) fit more snugly than narrow bands. If you are ordering a wide band, consider going up half a size from your usual measurement for a comfortable fit.

Account for Your Knuckle

If your knuckle is significantly larger than the base of your finger, measure both and choose a size in between. The ring should slide over your knuckle with slight resistance but sit comfortably at the base.

Measure Multiple Times

We recommend measuring at least twice on different days to confirm your size. Temperature, humidity, and physical activity can all affect finger size.

Local Jewelry Shop

We advise to trust some experts around you, drop by to a local jewelry shop and ask them to measure your specific finger - surely they will be happy to help and it will help us being more precise.

Common Questions

Frequently Asked

What if I'm between two sizes?+

If your measurement falls between two sizes, we recommend selecting the larger size for comfort. For narrow bands (under 4mm), the smaller size may also work well. If you are unsure, our team is happy to advise.

Do you offer complimentary resizing?+

Yes. We offer endless resizing once you purchase a piece of jewelry from us. Certain designs with continuous settings or engravings may have limitations.

For international customers, please contact us before sending your piece back for resizing. We will help prepare the necessary shipping documents so you won't be charged additional duties or taxes when your item is returned to you.

Can I visit the studio for a professional sizing?+

Absolutely. We welcome you to visit our Old Jaffa studio for a complimentary professional ring sizing. Our artisans use precision tools to determine your exact size and can advise on the best fit for different band widths and styles.

Does finger size change over time?+

Yes, finger size can change due to weight fluctuation, temperature, pregnancy, and age. If it has been more than a year since your last measurement, we recommend re-measuring before placing a new order.

How do I measure for a surprise gift?+

The easiest method is to borrow a ring the recipient wears on the intended finger and measure its interior diameter using Method Two above. Alternatively, you can trace the inside of the ring on paper and bring it to our studio. If you are still unsure, we always offer resizing after purchase.

Are Kwintner ring sizes the same as standard Israeli sizes?+

Yes. Kwintner uses the standard Israeli ring sizing system, which is based on the inner circumference in millimetres. Our conversion table above maps Israeli sizes to US, UK, and EU equivalents for your convenience.
