Every Sarnion piece is cast to order in our Istanbul workshop, in the size you choose at checkout. Rings come in quarter sizes from 3 to 15 US, so you never have to settle for "close enough". Use the on-screen sizer above, the printable sizer, or the table below; if you are still unsure, write to support@sarnion.com with your measurements and we will confirm the size for you.

Rings

Three ways to find your size

1. A ring you already own. Pick one that fits the same finger. Measure its inner diameter with a ruler, use the on-screen sizer above, or lay it over the circles on the printable sizer. Then read the size from the table.
2. A strip of paper. Cut a strip about 5 mm wide. Wrap it around the base of the finger, snug but not tight, and make sure it also slides over the knuckle. Mark where it overlaps, measure the length in millimetres: that is your circumference.
3. The printable Sarnion sizer. One sheet with a print check, size circles and a cut-out strip: A4 · US Letter. Print at 100% with scaling off and check the card outline before you trust it.

Using the on-screen sizer

The sizer at the top of this page (and under the size box on every ring page) turns your screen into a measuring tool. It is accurate to about a quarter size when you follow these steps:

1. Calibrate once. Pick a reference you have to hand, a US quarter by default, and lay it flat on the dark disc. Move the slider until the disc is hidden exactly under the coin: no dark rim peeking out, no light gap around the coin. With a bank card, match the outline to the card’s short edge. Tap It matches; we remember the setting for this device.
2. Place a ring that fits the finger you are buying for flat on the disc. Hold the phone level and look straight down, not at an angle.
3. Grow or shrink the disc until it fills the inside of the ring exactly: no light showing between disc and metal, and the disc not disappearing under the metal. The − and + buttons move it by a twentieth of a millimetre.
4. Read your size. We show the US quarter size, the diameter and circumference in millimetres, and the UK, EU and Italian equivalents. On a ring page, Use this size selects it for you.
5. Keep the browser at 100% zoom and recalibrate if you switch phone or computer; the setting belongs to the screen it was made on.

Measuring with a slim ring but buying a wide band of 8 mm or more? Go a quarter to half size up: wide bands fit tighter.

Five rules for a good fit

• Measure in the evening, at room temperature. Fingers are smaller in the morning and in the cold, larger in heat and after exercise.
• The ring should slide over the knuckle with slight resistance and sit at the base without spinning.
• Wide bands (8 mm and more) fit tighter than slim ones: take a quarter size up.
• Between two sizes? Order the quarter in between. We cast it.
• Each finger is different, and the dominant hand is usually a quarter to half a size larger. Measure the exact finger you will wear the ring on.

Bracelets

Measure your wrist with a tape measure, or a strip of paper and a ruler, just above the wrist bone where the bracelet will sit. Choose the bracelet size that matches your wrist measurement; if you prefer a looser fit, take the next size up. Between two sizes, take the larger one.

Bracelet sizes are given on each product page as wrist ranges in inches and centimetres (6.5–7 in / 16–17 cm, and so on). Email support@sarnion.com if you would like us to confirm.

Pendants and chains

Chain length is the full length of the chain when open. "Only Pendant" means the pendant ships without a chain and fits most chains up to 4 mm thick.

Length is the first decision when choosing a chain: before the link style, before the finish, it decides where the pendant sits. Our chains run from 16 to 30 inches; where each one falls depends on your neck and build, so use the images and table as a guide.

Men

Women

Not sure between two? Measure around the base of your neck with a tape or a strip of paper; a chain 2 to 4 inches longer than that sits comfortably at the collarbone, and every extra 2 inches drops the pendant about an inch lower.

Pendant size is the height of the pendant including the bail (the loop the chain passes through), measured vertically at the longest point; width is measured at the widest point. Where a pendant comes in several sizes, the dimensions of each are listed on the product page.
