Sizing

A well‑fitting ring should resist sliding over the knuckle, yet remove without pain. Sizing can be exacting but we offer clear paths to help you find yours.

For the most accurate fit, visit a jeweler. Try various rings or bring your own. Sizing standards include US, UK/AUS, EU, and Japanese. Always measure the specific finger and do so at a warm temperature, when hands are most natural in size.

Place a well‑fitting ring over a ruler, measuring its inner diameter at the widest point. Alternatively, wrap string just below your knuckle, mark, and measure. If between sizes, we suggest choosing the larger one.

Ring sizing example — this ring measures 19 mm in inside diameter.

Every order includes our ring sizer. Insert the end through the buckle, tighten it over the knuckle, and slide it to the base. Read the size at the arrow. Unsure? Email a photo to hola@sarjewellery.com for guidance.

You can also order a ring sizer on its own, free of charge:

A few important notes on sizing

Finger size can change throughout the day due to temperature and activity. For best results, measure at a comfortable, normal temperature
Avoid sizing only to your knuckle. If the ring fits the knuckle too tightly, it may feel loose once it sits at the base of the finger
Ring fit is personal. Some prefer a snug feel, others slightly looser
Wider or heavier designs may feel tighter than thinner bands, even in the same size

If your ring feels slightly tight or loose when it first arrives, we recommend wearing it for a few days before deciding on a resize. Fingers naturally change throughout the day, and it can take time to understand what feels right for you.
