A complete Algerian ring size guide for 2026 — measure your finger or an existing ring, calculate the nearest Algeria/French/EU size, compare international conversions and understand French and Arabic jewellery terminology used when buying rings in Algeria.
Print at 100% or “actual size”. First measure the 50 mm calibration line with a physical ruler. Only use the circles when the line prints at exactly 50 mm. Place a comfortable ring over a circle and align the ring’s inside edge, not the outside metal edge.
A 54 mm inner circumference gives practical size 54.
Example: 5.6 cm becomes 56 mm, or size 56.
A 17.19 mm diameter gives approximately 54 mm circumference.
A 58 mm circumference gives about 18.46 mm diameter.
US numbers are different and should be checked against the seller’s chart.
UK letters are useful for imported rings but are not the primary Algerian reference.
The calculator selects the nearest whole circumference size between 40 and 76. Some Algerian jewellers stock only selected even sizes or use an imported brand’s own chart.

Measure the finger on which the ring will actually be worn. The same named finger can differ between the left and right hand. Remove other rings and let your hands settle at a comfortable indoor temperature.
Cut a paper strip about 5 mm wide. Wrap it around the finger base without compressing the skin. The loop should be secure yet capable of passing over the knuckle. Avoid elastic thread, thick cord and flexible material that can stretch.
Mark exactly where the strip overlaps, lay it flat and measure from the starting edge to the mark. A reading of 5.4 cm equals 54 mm and therefore indicates practical Algeria/French/EU size 54.
Repeat at the same finger position and tension. If the results vary, use the most consistent reading and recheck on another day before ordering valuable jewellery.
A broad alliance or men’s band usually feels tighter than a narrow ring. The ring must pass the knuckle while remaining secure at the base, so professional fitting is recommended when those two measurements differ greatly.
Use a round, comfortable ring worn on the exact finger you are sizing. A ring from another finger or hand can give a misleading result.
Place the ring flat and measure across the widest internal point through the centre. Do not include the metal wall. A digital calliper is more accurate than a thick ruler.
Turn the ring approximately 90 degrees and measure again. Different readings can indicate an oval or damaged ring, in which case a jeweller should inspect it.
Select “Existing Ring Inner Diameter in MM”. An inner diameter near 17.2 mm converts to roughly 54 mm circumference, or Algeria/French/EU size 54.
Algeria’s jewellery market includes locally made pieces, French-language retail conventions, European imports and products labelled for the US, UK, Turkey, the Gulf or East Asia. As a result, a country name alone is not enough to guarantee the exact scale used by every shop. The clearest practical reference in Algeria is the French/continental European circumference number, because it can be communicated directly in millimetres.
Under this system, size 50 represents about 50 mm of inner circumference, size 54 represents about 54 mm and size 60 represents about 60 mm. The corresponding diameter is found by dividing the circumference by π. This direct link between the size number and the physical circumference makes French/EU sizing easier to verify than a conversion-only label.
When ordering from an Algerian jeweller, state both the requested size and the measurement: for example, “taille 54, tour intérieur environ 54 mm” or “مقاس 54، محيط داخلي حوالي 54 مم”. For imported jewellery, ask whether the number shown is French/EU, US or another brand system before payment.
French and Arabic are both useful when discussing ring sizing, custom work, exchanges and repairs in Algeria. These terms help you communicate the physical measurement rather than relying on a potentially ambiguous size number.
Broad rings often need more fitting allowance than slim bands.
The ring must pass the knuckle but remain secure at the base.
Heat and cold temporarily affect finger fullness.
Left and right hands can have different measurements.
Eternity and complex stone settings require precise sizing.
Rounded interiors can feel different from flat-edged bands.
