Borrow a ring they wear on the same finger, measure the inner diameter with a ruler in mm, then match to the size chart.
Place their ring on paper, trace the inner circle, measure the diameter of the traced circle, and look it up in the chart.
Enlist a trusted friend or family member of your partner to casually find out their ring size or go ring shopping together.
Visit a jewellery store "just to browse" and suggest trying on a few styles. The jeweller will measure both of you.
Compare your own finger to theirs. If their ring finger is the same size as your pinky or index finger, you can use your own known size as a reference.
Order a resizable ring or choose a design that comes in a range. Most jewellers offer one free resize within 30 days of purchase.
Both partners should measure in the evening when fingers are at their natural maximum size. Cold, morning, or post-exercise measurements will give inaccurate results.
Each partner cuts a strip about 1cm wide and 10cm long. Wrap snugly around the base of the ring finger — the finger you plan to wear the ring on.
Gently pull the paper over the knuckle. The ring must be able to pass over it comfortably. Mark where the paper meets and lay flat on a ruler.
Write down the circumference (mm) for each partner. Repeat 3 times and use the average value for accuracy.
Find each measurement in the Circumference column. If between two sizes, size up. For wide bands (6mm+), both partners should go up ½ a size.
Same design in different sizes. His is wider and heavier; hers is slimmer with the same pattern or motif.
Her ring in yellow gold, his in white gold or silver. Different metals with matching design elements create a stylish pair.
Different outer designs but matching hidden engravings inside both rings — a date, name, or shared message only the couple knows.
Two rings that interlock or fit together to form a single image or shape. Popular for anniversary and commitment rings.
Thin, simple matching bands in the same metal. A timeless and versatile option for everyday wear for both partners.
Each ring features the partner's individual birthstone in a shared design framework — personalised yet perfectly matched.
