How to Measure Ring Size in Georgia at Home
Georgian jewellery commonly uses sizes such as 16, 17, 17.5 and 18, which correspond to the ring's inner diameter in millimetres. Measure an existing ring directly or convert finger circumference to diameter.
Choose the Exact Finger
Measure the hand and finger where the ring will be worn. The same finger on opposite hands can differ.
Use a Comfortable Ring
For the most direct local result, select a round ring that already fits the intended finger.
Measure Inner Diameter
Measure straight across the clear inside opening through the centre, excluding the metal edges.
Read the Georgian Size
An inner diameter of 17.5 mm is Georgian size 17.5. The calculator shows EU, US and UK equivalents.

Georgian Diameter Size
The local number follows inner diameter in millimetres. Examples include 16, 16.5, 17, 17.5, 18 and 18.5.
European Circumference Size
The EU number approximately follows inner circumference in millimetres. Georgian 17.5 is near EU 55.

The Georgian column follows the practical diameter-based convention seen in local product listings. EU, US and UK values are approximate because international systems use different increments and brands may round differently. Confirm the exact seller's chart before ordering.
Choose the exact finger and hand
Measure the finger where the ring will actually be worn. The same finger on opposite hands can differ, especially between dominant and non-dominant hands.
Prefer a correctly fitting existing ring
A local diameter-based size is easiest to determine from a round ring that already fits the intended finger comfortably.
Measure the clear inner diameter
Place the ring flat and measure straight across the widest internal point through the centre. Do not include the metal edges. Record the result in millimetres.
Rotate and repeat
Turn the ring approximately 90 degrees and measure again. Different results may mean the ring is oval or the ruler missed the true centre.
Use the nearest half-millimetre size
If the result is 17.4โ17.6 mm, Georgian size 17.5 is the practical starting point. Confirm the exact fit and ring width with the seller or jeweller.
Use a non-stretch paper strip
Wrap a narrow strip around the finger base. Keep it snug without squeezing and make sure it can pass over the knuckle.
Mark the overlap
Use a fine pen, lay the strip flat and measure the length in millimetres. This is the finger circumference.
Convert circumference to diameter
Divide the circumference by ฯ. A 55 mm circumference gives approximately 17.5 mm diameter and Georgian size 17.5.
Repeat under normal conditions
Take at least three readings. If the result falls between two half sizes, choose the larger size for comfort unless a professional jeweller recommends otherwise.
Verify Print Scale Before Using a Printable Ring Guide
Print at 100% or โActual Sizeโ. Do not choose โFit to Pageโ, shrinking or automatic scaling. After printing, measure the line below with a physical ruler. It must equal exactly 50 mm or the printed ring circles will be inaccurate.
Season and Temperature
Cold weather can make fingers feel smaller, while heat can make them fuller.
Time of Day
Finger size can change during the day, so compare several ordinary readings.
Wide Bands
Local Georgia guidance notes that wider rings may require a slightly larger fit.
Large Knuckles
The ring must pass the knuckle while remaining secure at the finger base.
Paper Measurement
Paper can bend or shift. A rigid ring gauge is more accurate for valuable jewellery.
Ring Construction
Eternity stones, engraving and some hard materials can limit resizing.
Confirm that the local number means inner diameter
Georgian stores commonly list sizes such as 17, 17.5 or 18. Ask the seller to confirm that the number represents inner diameter in millimetres and request the matching circumference.
Write the complete result for international orders
Save a note such as โGeorgian 17.5 / 17.5 mm diameter / 55.0 mm circumference / EU approximately 55 / US approximately 7โ7.5.โ This prevents an overseas seller from treating 17.5 as another regional scale.
Use the exact brand chart for the final selection
Local Georgian brands may provide visual charts or design-specific sizing advice. The calculator offers a consistent conversion framework, but the exact product chart should control the final order.
Consider wide and stacking rings
Margot Georgia advises that wider rings generally need a slightly larger size and suggests choosing the larger option when a measurement falls between sizes. Multiple rings worn together can also feel tighter.
Check resizing before paying
Ask whether the design can be resized, what adjustment range is possible and whether engraving or stone settings affect the service. Full-eternity and complex pavรฉ designs may be difficult to alter.
Use professional sizing for valuable jewellery
A jeweller can use calibrated finger gauges and a ring mandrel, account for the knuckle and evaluate band width. Professional confirmation is recommended for engagement rings, wedding bands and custom pieces.

Georgian product pages use sizes from 14 to 24
IKANI, a Georgian handmade jewellery seller, lists ring options including 14, 14.5, 15, 16.5, 17, 17.5, 18 and sizes up to 24. This is consistent with the local diameter-based format.
Local listings explicitly describe ring size in millimetres
Georgian product pages describe rings as size 17 mm or 17.5 mm. This directly supports reading the local size as the ring's internal diameter rather than its circumference.
Local brands teach both existing-ring and finger methods
Margot Georgia recommends measuring an existing ring's internal diameter in millimetres or measuring finger circumference with a paper strip. It also advises choosing the larger size when the result falls between two options.
International conversions still matter
A Georgian size such as 17.5 can appear as EU 55, US about 7โ7.5 or UK around O on an international website. Millimetres provide the bridge between these labels.
Why Georgia uses an easy diameter reference
The practical Georgian sizing convention connects the ring number to its inner diameter in millimetres. This makes an existing ring especially useful: a measured 18 mm opening points directly to Georgian size 18.
Finger circumference and ring diameter are different
Finger circumference is the distance around the finger where the ring sits. Inner diameter is the straight distance across the empty ring opening. Circumference is approximately diameter multiplied by 3.1416.
Why half-millimetre sizes matter
Georgian stores commonly offer half sizes such as 16.5, 17.5 and 18.5. A half millimetre in diameter changes circumference by roughly 1.57 mm, which can noticeably affect comfort and security.
How a correctly fitted ring should feel
A comfortable ring passes over the knuckle with gentle resistance and remains secure at the finger base. It should not cause pain, numbness or a deep persistent mark. Top-heavy rings may need sizing beads rather than a substantially smaller diameter.
Climate, altitude and season can affect fit
Temperature, humidity, altitude and time of day can temporarily change finger size. Take several measurements under ordinary conditions and avoid making a permanent sizing decision from one unusually hot or cold reading.
Surprise engagement-ring sizing
Borrow a ring the recipient wears on the intended finger and measure the clear inner diameter. A ring from another finger is only a rough estimate. Select a design with a practical exchange or resizing policy when uncertainty remains.
Professional sizing remains the safest final check
Home measurement is useful for narrowing the range and comparing online charts. A professional jeweller can use rigid gauges, assess the knuckle and band width and advise whether the design can be resized.
