Use the measurements on each product page together with the guidance below. Fit is personal and can vary by design, so contact us before ordering if you need a product-specific measurement that is not shown.
Ring sizes use UK letter sizing; US and EU conversions are shown for reference. Adjustable rings are identified as adjustable on their product page, with the minimum and maximum fit stated where available.
Wrap a strip of paper or string snugly around the finger, mark where it overlaps, and measure to the mark in millimetres — that is the circumference. Or take a ring that already fits and measure across the inside at the widest point to match the inside diameter. Between sizes? Choose the larger.
