A complete Central African Republic ring-size guide for 2026 โ measure your finger or an existing ring, estimate the nearest French/EU circumference size, compare US, UK and Italian equivalents, and use a printable millimetre reference before buying in Bangui or online.
Use a narrow paper strip, mark the overlap, measure the length in millimetres and match it to the nearest French/EU circumference size. A 54 mm result is approximately size 54.
Use ordinary paper or a flexible non-stretch tape. Avoid elastic string.
Place it where the ring will sit and make sure it can pass the knuckle.
A thick mark can change the result by a full metric size step.
Lay the strip flat and measure from the starting edge to the mark.
Use the closest consistent result taken under ordinary conditions.
Send the physical measurement to the retailer before ordering.

The chart rounds physical measurements to familiar retail labels. Keep the exact millimetre value when comparing brands because international conversion tables can differ by a quarter or half size.
Measure the finger on which the ring will actually be worn. The same finger on the opposite hand can have a different circumference, especially on the dominant hand.
Cut a paper strip about 5โ8 mm wide or use a flexible non-elastic measuring tape. Avoid thick cord, elastic thread and soft string that can twist or compress the skin.
The strip should touch the skin without squeezing it. Check that the loop passes over the knuckle with gentle resistance and remains reasonably secure at the finger base.
Mark the exact overlap with a fine pen, lay the strip flat and measure from the starting edge to the mark. Enter the result as circumference in millimetres.
Take at least three readings during an ordinary part of the day. Avoid measuring immediately after strenuous activity, prolonged heat, a hot shower or exposure to cold conditions.
Use a round ring that fits comfortably on the correct hand and finger. A ring from another finger is not a reliable substitute.
Place the ring flat and measure straight across the widest internal opening through the centre. Do not include either metal edge.
Turn the ring approximately 90 degrees and measure again. Different readings may indicate that the ring is slightly oval or distorted.
Select โExisting Ring Diameter in MM.โ A 17.3 mm internal diameter is near 54.4 mm circumference and approximately French/EU size 54.
Example: 54.0 mm inner circumference is approximately size 54.
Example: EU 54 is approximately Italian or Spanish size 14.
17.2 mm diameter ร 3.1416 โ 54.0 mm circumference.
54.0 mm circumference รท 3.1416 โ 17.2 mm diameter.
5.4 cm circumference equals 54 mm circumference.
Convert to millimetres before matching a French/EU chart.
First measure the calibration line with a physical ruler. It must be exactly 50 mm. Then place a comfortable existing ring over the circles and match the inside edge, not the outside edge.
Wedding bands and statement rings cover more skin than narrow rings.
The ring must pass the knuckle and remain secure at the finger base.
Heat can make fingers fuller, while cold can temporarily reduce the size.
Finger dimensions can differ between the left and right hands.
Elastic thread can tighten and produce a reading that is too small.
Rounded interiors can feel different from flat interiors at the same diameter.
