Jewelry Size Guide: Ring, Bracelet & Necklace

Finding the perfect jewelry size is essential for comfort and style. Use our complete jewelry size guide to find your ideal ring, bracelet, or necklace fit. This guide includes a ring size chart, bracelet size chart in cm, and necklace length guide, along with simple methods to measure your size at home — or free in-store sizing at our Dubai boutique.

This jewelry size guide is designed for UAE customers and includes international size conversions for accurate fitting.

Ring Size Chart (EU, US & Inner Diameter)

Use this ring size chart to find your correct size. Luna Dura rings are ordered in EU sizes, so if you know your US size — common for shoppers and visitors across Dubai and the UAE — find it in the US column and order the EU size on the same row. Inner diameter in millimetres is the exact reference: if your US size falls between two rows, choose the larger EU size for a comfortable fit.

EU Size	US Size (nearest)	Inner Diameter (mm)	Circumference (mm)
49	5	15.6	49
50	5.25	15.9	50
51	5.75	16.2	51
52	6	16.5	52
53	6.5	16.9	53
54	7	17.2	54
55	7.25	17.5	55
56	7.75	17.8	56
57	8.25	18.2	57
58	8.5	18.5	58
59	9	18.8	59
60	9.25	19.0	60
61	9.75	19.4	61
62	10	19.7	62

Get Sized Free at Our Dubai Boutique

If you are in Dubai, the most accurate way to find your size is in person — and it is free. Visit the Luna Dura boutique at Al Durrah Tower on Sheikh Zayed Road, opposite the Museum of the Future. Bring a ring you already wear and we will measure it for you, or use our professional ring sizer in store. No purchase necessary. For visitors and residents alike, this removes all guesswork before you buy.

How to Measure Ring Size at Home

If you cannot visit in person, you can measure your ring size at home using a string or paper strip. Wrap it around the base of your finger, mark where it overlaps, and measure the length in millimetres. That length is your finger's circumference, which matches the circumference column above directly — for example, a 54 mm measurement is an EU 54. Match it to the chart to find your EU and US size.

Measure at the end of the day, when fingers are at their largest
Avoid measuring when your hands are cold
Make sure the size slides comfortably over your knuckle
For wide bands (around 6 mm or more), choose one size up — wider bands sit more snugly
If your knuckle is wider than the base of your finger, measure both and choose a size in between
Measure two or three times to confirm, and note that your left and right hands can differ slightly

How to Measure an Existing Ring

If you already own a ring that fits the right finger, you can size it directly. Lay the ring flat and measure the inside edge-to-edge distance across the centre in millimetres — this is the inner diameter. Match that figure to the Inner Diameter column above to find the matching EU and US size. Measuring an existing ring is often more reliable than measuring the finger, as it accounts for the exact fit you already wear comfortably.

What Size Should I Buy as a Gift?

Choosing a ring as a surprise is easier than it seems. The average ring size for women in the region falls around EU 54 (US 7), a safe starting point if you are unsure. If the fit is not quite right, our ring resizing is complimentary — and we will re-plate the piece for a fresh finish if you would like, also free of charge. Please note that once a ring has been resized or re-plated, it is considered final sale and is no longer eligible for return, as the piece has been adjusted specifically for you. To narrow it down before buying, you can also discreetly measure a ring the recipient already wears using the existing-ring method above.

Bracelet Size Chart (cm Guide)

Use this bracelet size chart to find the perfect fit based on your wrist measurement. This guide is ideal for women's bracelets and includes sizing in centimeters.

Measure your wrist just above the wrist bone and add:

+1 cm for a snug fit
+2 cm for a comfortable fit
+3 cm for a loose fit

Wrist Size (cm)	Bracelet Size (cm)	Fit
14–15	16	Snug
15–16	17	Comfort
16–17	18	Loose
17–18	19	Loose

Necklace Length Guide (Choker, Princess & Long Chain)

Use this necklace length guide to choose the perfect chain size for your style. Different necklace lengths sit at different points on the body, making them ideal for layering or standalone wear.

40 cm (Choker): Sits high on the neck, perfect for layering and modern styling.
45 cm (Princess): The most popular necklace length, resting on the collarbone.
50–60 cm (Matinee): Falls below the collarbone, ideal for elegant or layered looks.
70 cm+ (Long Chain): Creates a long, vertical silhouette and works well for layering.

This necklace length chart is ideal for women looking to layer necklaces or choose an everyday chain length.

Frequently Asked Questions

How do I measure my ring size without a ring?

You can measure your ring size using a string or paper. Wrap it around your finger, measure the length in millimetres, and compare it with the circumference column in the ring size chart.

What is the average ring size for women?

The average ring size for women in the region is around EU 54 (US 7), though it can vary. If you are buying a surprise gift, the average size is a safe starting point.

Are UAE ring sizes the same as US sizes?

Many jewelers in the UAE use US ring sizes, while others use European sizing. Luna Dura rings are ordered in EU sizes, so the chart includes a US column and inner diameter to convert reliably between the two.
