Choose the Right Ring
Select a ring that fits well on the same finger and hand where the new ring will be worn.
RING SIZE GUIDE
A well-fitting ring should feel secure without feeling tight. Use a ring you already own or measure your finger at home, then compare your result with our size chart.
For the most reliable result, measure more than once and compare both methods when possible.
METHOD ONE
Choose a ring that fits the intended finger comfortably. Ring size can vary between fingers and between hands.
Select a ring that fits well on the same finger and hand where the new ring will be worn.
Place the ring on a flat surface. Measure straight across the widest part of the inside opening in millimeters. Do not include the metal edges.
Compare the inside diameter with the chart below. If the measurement sits between two sizes, the larger size is usually the more comfortable starting point.
METHOD TWO
You will need a narrow strip of non-stretch paper, a pen and a ruler marked in millimeters.
Wrap the paper around the base of the finger where the ring will sit. Keep it flat against the skin without pulling too tightly.
Mark the point where the two ends of the paper meet.
Lay the paper flat and measure from its starting edge to the mark in millimeters. This is your finger circumference.
Compare the measured circumference with the chart below and choose the closest corresponding US ring size.
Match your measurement to the closest size below. Measurements are approximate and may vary slightly depending on the ring design and the way you prefer your ring to fit.

Finger size changes slightly throughout the day. A few small checks can make your measurement more reliable.
Fingers are often slightly fuller later in the day than first thing in the morning.
Cold fingers may measure smaller, while heat can temporarily make them feel larger. Measure when your hands feel at a normal, comfortable temperature.
The same finger may not be identical on both hands. Always measure the hand where the ring will be worn.
The ring should pass over the knuckle without excessive force while still sitting securely at the base of the finger.
Wide bands and stacked rings usually feel more snug than slim bands. Depending on the design, a slightly larger size may feel more comfortable.
Measure two or three times on different occasions. If the results vary, confirm the size with a reputable local jeweler before ordering.
The ring spins often, slides too easily, or feels at risk of slipping off during daily movement.
The ring sits securely at the base of the finger and passes over the knuckle with gentle resistance.
The ring feels uncomfortable, leaves a deep mark, or becomes difficult to remove from the finger.
A light temporary impression can be normal. Persistent pressure, discomfort or swelling is not.
Ring size is only part of the fit. Band width, interior shape, stone setting and stacking style can all affect how a ring feels on the hand.
Slim bands generally follow your standard ring size more closely.
Wider bands cover more of the finger and may feel tighter.
Several rings worn together can fit more snugly than each ring worn alone.
Open designs may allow limited flexibility, but they should not be repeatedly bent or forced.
SURPRISE SIZING
Borrow a ring they already wear comfortably on the intended finger and measure its inside diameter. If possible, ask someone close to them to confirm the size.
A ring worn on another finger, or on the opposite hand, may not provide an accurate match.
Professional measurement by a reputable local jeweler is usually the most reliable option. At home, compare the inside diameter of a well-fitting ring with your finger circumference and repeat the measurement more than once.
The larger size is often the more comfortable starting point, especially for wider bands. However, the best choice depends on the ring design, your knuckle and how you prefer the ring to feel.
Not always. Fingers on your dominant hand may measure slightly differently. Measure the exact finger and hand where the ring will be worn.
Yes. Wide bands and several stacked rings usually feel more snug than a single slim band. A different size may be recommended for these styles.
It may provide a rough reference, but it is not a reliable measurement. For the best result, use a ring worn on the same finger and hand.
No. Resizing depends on the metal, stone setting and construction of the ring. Eternity bands, intricate pave designs and some sculptural styles may have limited resizing options.
Compare both home methods, repeat the measurement on another occasion and confirm the result with a reputable local jeweler before ordering.
A GENTLE STARTING POINT
Home measurement is a helpful starting point. For special designs, wide bands, eternity styles or any ring that may be difficult to resize, confirm your size locally before finalizing the piece.
