A complete Mozambique ring-size guide for 2026 — measure a finger or an existing ring, calculate a metric/EU circumference size, compare Portuguese, UK/South African and US equivalents, and use a printable millimetre gauge before ordering in Maputo, Beira, Nampula or online.
The highlighted ranges are orientation examples rather than gender rules. Finger shape, knuckle width, band profile and the seller’s own manufacturing tolerances are more important than averages.
A label such as “size 14”, “size N” or “size 7” is incomplete without the sizing system. A measurement such as 17.2 mm inner diameter and 54.0 mm circumference is unambiguous and can be compared with European, Portuguese, South African or American charts.

The metric/EU number is based on inner circumference in millimetres. Portuguese, UK/South African and US equivalents are rounded comparisons; manufacturers may group or round sizes differently.
Measure the finger on which the ring will actually be worn. The same finger on the opposite hand can differ, especially on the dominant hand. Remove other rings and allow the hand to rest before measuring.
Cut a strip of ordinary paper about 5–8 mm wide or use a flexible non-elastic tape. Avoid elastic thread, thick cord and soft string that can tighten, twist or sink into the skin.
Place the strip at the ring's intended position. It should touch the skin without compressing it. Check that the loop can pass over the knuckle with gentle resistance, particularly if the knuckle is wider than the finger base.
Use a fine pen to mark where the strip overlaps. Lay it flat and measure from the starting edge to the mark. A length of 54 mm is approximately metric/EU size 54 and often Portuguese aro 14. Do not confuse 5.4 cm with 54 mm when entering the calculator.
Repeat at least three times during a normal part of the day. Do not measure immediately after intense exercise, carrying heavy bags, prolonged heat exposure, a very salty meal or a long period in cold air conditioning.
Use a round ring that fits the intended finger comfortably. A ring from another finger is not a reliable substitute.
Place the ring flat and measure the widest internal opening straight through the centre. Exclude both metal edges.
Rotate the ring by about 90 degrees and repeat. Different results can indicate an oval or distorted ring.
17.2 × π ≈ 54.0 mm circumference → Mozambique / French-EU size 54.
A digital calliper is usually more repeatable than reading a thick ruler. When using a ruler, align one internal edge with zero and view from directly above to reduce parallax error.
First measure the calibration line. It must be exactly 50 mm. Place a comfortable ring over the circles and match the inside edge of the metal to the outside edge of the printed circle. Do not use “Fit to Page”, “Shrink” or automatic scaling.
Example: 54.0 mm circumference is approximately size 54.
Example: 17.19 mm × 3.1416 ≈ 54.0 mm.
Example: 54.0 mm ÷ 3.1416 ≈ 17.19 mm.
Example: EU 54 is approximately Portuguese/Italian/Spanish size 14.
US sizes use a separate scale and quarter sizes, so the result is approximate.
UK sizes use letters and half letters. Keep the millimetre reading for accuracy.
High outdoor temperatures can make a normal ring feel tighter later in the day.
Exercise, walking and fluid retention can change the result for a short time.
A broad wedding band covers more skin and can need additional space.
The ring must pass the knuckle while remaining reasonably secure at the base.
Dominant and non-dominant hands do not always have identical finger sizes.
Rounded interiors can feel different from flat interiors at the same diameter.
Thin fashion rings and many engagement-ring shanks usually create less pressure. A carefully repeated home measurement may be close to the final size, but top-heavy settings can still spin even when the circumference is correct.
A broad band covers more skin and resists movement. The same internal opening may feel tighter than a narrow ring. Do not add a fixed size automatically; test a sample of similar width or follow the maker's recommendation.
Ask about resizing before paying, not after the ring arrives. Plain gold or platinum bands are often easier to adjust than full-eternity rings, tension settings, ceramic rings, patterned bands, heavily plated jewellery or rings with stones around most of the circumference.
