Ring Sizing 

Method 1: Measure an Existing Ring 

1. Pick a ring that fits the target finger well.

2. Measure the inside diameter in millimeters (mm).

3. Match your measurement to the chart below.

Method 2: String/Paper Strip 

1. Wrap a thin string or paper strip around your finger where the ring will sit.

2. Mark where it overlaps.

3. Unwrap and measure the length in mm—this is the finger circumference.

4. For EU sizes, the mm circumference ≈ EU size (e.g., 54 mm ≈ EU 54).

5. For US sizes, use the chart below.

Pro tips:

• Measure at the end of the day (fingers are slightly larger).

• Avoid cold temperatures when measuring.

• For wide bands, go ½ size up.

• Measure 3 times and use the average.

Note: Results vary slightly by design and band thickness. Between sizes? Choose the larger for comfort.

Bracelet Sizing 

Chain/Link/Adjustable Bracelets 

1. Measure wrist circumference with a soft tape (or string + ruler).

2. Add +1.5 to +2 cm for a comfy everyday fit.

3. For a very snug, tailored fit, +1 cm may work.

Solid/Bangle Bracelets 

1. Measure the hand circumference across the knuckles (where the bangle must pass).

2. Divide by π (≈3.14) to get the minimum inner diameter.

3. Choose a bangle slightly larger than that diameter.

Common Women’s Bracelet Lengths:

• XS ≈ 16 cm | S ≈ 17 cm | M ≈ 18 cm | L ≈ 19 cm | XL ≈ 20 cm (inner length)

Necklace Lengths

Popular Lengths & Where They Sit:

Layering tips:

• Stack 2–3 necklaces with 2–4 inches between each length.

• Petite necks: 16"–18". Fuller necks: 18"–20"+.

• Consider your neckline for the best visual balance.

Earring Sizing 

Studs 

• Minimal: 3–4 mm

• Everyday: 5–6 mm

• Statement: 7–8 mm+

Hoops (Diameter in mm) 

• Huggie: 10–15 mm (close to the ear)

• Everyday: 20–30 mm

• Bold: 40–50 mm+

Drops/Dangles 

• Easy everyday length: 20–40 mm

• Piercing placement (higher/lower) changes how long they appear—adjust accordingly.

Fast Reference Summaries

Rings:

• String method → circumference in mm → map to EU (≈ same number) or US with the chart.

• Wide bands: go ½ size up.

Bracelets:

• Wrist circumference + 1.5–2 cm (chain/adjustable).

• For bangles: hand circumference ÷ 3.14 = inner diameter → pick slightly larger.

Necklaces:

• 18" Princess is most popular. For stacks, space by 2–4".

Earrings:

• Everyday hoops 20–30 mm; huggies 10–15 mm; studs 5–6 mm.

FAQs 

Q: I’m between two ring sizes—what should I pick?
A: Choose the larger for comfort, especially for wider bands. Measure 2–3 times and average.

Q: When is the best time to measure?
A: Evening. Fingers and wrists can swell slightly during the day. Avoid cold temps.

Q: How much extra should I add for bracelets?
A: Chain/Link: +1.5–2 cm for comfy everyday wear. Bangles: compute inner diameter from hand circumference ÷ π and pick a touch larger.

Q: What necklace length is best for daily wear?
A: 18" (Princess) fits most necklines. For layering, space each piece by 2–4".

Q: What hoop size works for everyday?
A: 20–30 mm is a versatile sweet spot. For snug hoops, try 10–15 mm huggies.
