A complete Algerian ring size guide for 2026 โ measure your finger or an existing ring, calculate the nearest Algeria/French/EU circumference size, compare international conversions, and understand the Arabic and French jewellery terminology used when buying rings in Algiers, Oran, Constantine, Annaba, Blida or elsewhere in Algeria.
Print at 100% or โactual sizeโ. 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 52 mm inner circumference corresponds to French/EU size 52.
Example: 5.6 cm ร 10 = 56 mm, pointing to size 56.
A 17.19 mm inner diameter gives approximately 54 mm circumference.
A 60 mm circumference gives an inner diameter of about 19.10 mm.
US sizes follow a different numerical scale, so keep the millimetre value.
UK letters help comparison but should not replace a measured circumference.
The calculator selects the nearest whole circumference size. Confirm the result with the exact Algerian retailer, jeweller or imported brand, especially for wide, engraved, expensive or difficult-to-resize rings.

Choose the finger on which the ring will actually be worn. The same finger on the left and right hand can differ, and a ring that fits the middle finger may not fit the ring finger. Remove other rings and let your hands return to a normal room temperature before measuring.
Cut a paper strip approximately 5 mm wide. Wrap it around the base of the finger without compressing the skin. The loop should be secure but still capable of passing over the knuckle. Avoid elastic string, thick cord and fabric tape that can stretch or twist.
Mark the precise point where the strip overlaps. Lay it flat and measure from the starting edge to the mark. Record the result as the finger's circumference. For example, a reading of 5.4 cm equals 54 mm and therefore points to Algeria/EU size 54.
Repeat the measurement and compare the results. If the values change, check that the strip is sitting in the same position and with the same tension. Use the most consistent reading rather than a single unusually tight or loose measurement.
A broad wedding band usually feels tighter than a narrow engagement ring. Full-eternity rings, complex stone settings and engraved bands may be difficult to resize, so confirm the size with an Algerian jeweller before placing a high-value order.
Use a round, comfortable ring worn on the exact finger you are sizing. A ring borrowed from another finger or hand can produce a misleading result.
Place the ring flat and measure straight across the widest internal point through the centre. Do not include the metal wall. A digital calliper is more precise than a thick ruler, but a clear millimetre ruler can give a useful estimate.
Turn the ring about 90 degrees and measure again. Matching readings suggest a round ring. Different readings can indicate an oval or damaged band, in which case professional sizing is safer.
Select โExisting Ring Inner Diameter in MMโ, enter the result and compare it with the Algeria/EU chart. For example, an inner diameter near 17.2 mm converts to about 54 mm circumference, or EU size 54.
Algeriaโs jewellery market includes local goldsmiths, traditional jewellery specialists, French-language retailers, imported brands and online marketplaces. Because of that mix, a product may be labelled with a French/EU circumference number, a US number, a UK letter or only the inner diameter. The most reliable common language is the physical measurement in millimetres.
In the French/EU system, the ring number closely matches the internal circumference. A size 54 therefore means approximately 54 mm around the inside of the ring, corresponding to an inner diameter near 17.19 mm. This direct relationship makes circumference particularly useful when speaking with a jeweller in Algeria or ordering from a European seller.
Do not mistake the diameter for the size number. A ring measuring about 17.2 mm across its internal opening is close to French/EU size 54, not size 17. If the listing provides only US or UK sizing, send the seller your measured circumference and ask for the nearest equivalent before paying.
For a custom ring, describe the intended finger, desired band width and measured size in both French and Arabic when helpful: taille 54 / tour de doigt 54 mm / diamรจtre intรฉrieur environ 17,19 mm, or ู ูุงุณ 54 / ู ุญูุท ุงูุฅุตุจุน 54 ู ู / ุงููุทุฑ ุงูุฏุงุฎูู ุญูุงูู 17.19 ู ู .
Algerian jewellery businesses may communicate in Arabic, French or both. These terms help you describe the measurement accurately without relying on an uncertain international conversion:
The Arabic phrase for the size of a ring.
The French phrase commonly used in size guides and product listings.
The measurement around the intended finger.
Give this value in millimetres for the clearest conversion.
The straight distance across the ringโs empty internal opening.
Measure through the centre without including the metal wall.
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 and comfort.
The same named finger can differ between left and right hands.
Eternity bands and complex settings need more precise sizing.
Rounded interiors can feel different from flat-edged interiors.
Do not assume every number is French/EU. Read the chart headings and determine whether the listing uses circumference, inner diameter, US sizes or UK letters.
A broad flat-edged ring can feel tighter than a narrow comfort-fit band. Check width, thickness, inner profile and whether stones continue around the full circumference.
Imported orders, engraved rings and made-to-order pieces may have special return conditions. Check who pays delivery or customs-related costs if an exchange is required.
Keep the order as French/EU 52, circumference 52 mm and inner diameter approximately 16.55 mm. This is more useful than a size number alone if support is needed later.
Algerian Customs publishes information on gold, silver and platinum articles and links precious-metal activity to the relevant customs and regulatory framework. Executive Decree No. 15-169 of 23 June 2015 sets approval arrangements for activities involving the importation of raw, semi-worked or worked gold, silver and platinum, as well as recovery and recycling activity. A 2019 official regulation also records obligations for approved importers.
Algeria also has legal texts concerning title and guarantee punches for precious-metal works. These rules concern metal control and commercial activity; they do not define the wearerโs ring size. When buying jewellery, ask the seller to identify the alloy and fineness in writing, provide an itemised receipt, and explain any responsibility, fineness or guarantee marks visible on the article.
For antique, inherited or heavily worn jewellery, a faint stamp is not enough to establish authenticity. A qualified jeweller or authorised specialist should inspect the metal, construction, repairs and stones. Resizing may also disturb an old mark, engraving, surface pattern or solder joint, so document the ring before alteration.
Many plain gold, silver or platinum bands can be resized, but the safe adjustment depends on the alloy, thickness, width, pattern, stone arrangement and previous repairs. Full-eternity rings, tension settings, enamel, ceramic components and mixed-metal designs may be difficult or impossible to alter neatly.
For a slightly loose ring, a jeweller may recommend sizing beads, an inner insert or another reversible solution. A tight ring should not be forced over swelling. Pain, numbness, colour change or deep indentation is a reason to remove it promptly.
Before resizing a valuable Algerian, imported or traditional ring, ask how the work may affect the hallmark, fineness stamp, engraving, decorative pattern, stone security and warranty. Obtain the proposed finished size in millimetres, not only a verbal instruction to make it โslightly largerโ or โslightly smallerโ.
