Ring size chart (EU/PL)

Cut a narrow strip of paper (or use thread), wrap it around the base of your finger, mark the point of contact, and measure in millimeters. Compare it to the Circumference (mm) column (in EU/PL, the number corresponds approximately to the circumference). It's easiest to use our 1:1 tape measure (PDF) and print at 100% scale.

Measure the inside diameter with a caliper or an accurate ruler (to the nearest 0.1 mm), ignoring the thickness of the ring. Then read the size in the Diameter (mm) column.

Approximately 16.5mm diameter and 52mm circumference. Other examples: 7 ≈ 14.8/46.5; 14 ≈ 17.2/54. For the complete conversion, see the table above.

Often yes. With a width of ~1 cm or more, it is usually +0.5 sizes (sometimes +1) more comfortable to wear than a narrow band.

In EU/PL, number ≈ circumference (mm), e.g. 52 ≈ 52 mm. For full mapping to US/UK, see the conversion tables (values ​​are approximate – different brands may round differently).

Borrow a ring worn on the same finger and match it to the hoops 1:1 (PDF). If you're torn between two sizes, choose the larger size—it's easier to slightly reduce it later.

Yes – temperature and swelling affect circumference. Measure in the evening, in neutral conditions, and leave a small margin of comfort in winter and summer.

In most models, yes (the range depends on the design/setting). Contact us – we'll tell you what adjustment range is safe for your chosen ring.

In practice, women's sizes often fall around 52-57 , but it is best to confirm with a 1:1 measurement - hands and styles vary.

This is a result of rounding ( diameter = circumference/π ) and manufacturing tolerances. Different brands also use different rounding schemes. Therefore, always confirm the result on 1:1 wheels.

Approximate US 5¾ (5.75) . Approximate dimensions: diameter ~16.2 mm , circumference ~51 mm . Always confirm on 1:1 wheels or measure with a caliper.

Choose a size that fits over your knuckle and doesn't fall off when resting. You can enhance comfort with beads (small balls inside the ring), a spring-loaded insert, or a slightly elliptical ring shape.

Yes, often by +0.5–1 size due to water retention. Avoid very tight fitting; consider temporarily sizing up and adjusting after pregnancy.

Not necessarily – the dominant hand is usually slightly larger. Measure the finger on which you will actually wear the ring (usually the ring finger of the left hand for an engagement).

Homemade accuracy is typically ±0.1-0.2 mm. Print the PDF at 100% and check the 0-100 mm ruler; if it differs by 1-2 mm, set it to "no scaling" and print again.
