Ring Size Guide
Choosing the perfect ring size ensures your ARCK piece feels as beautiful as it looks. Below are our tips for finding your ideal fit.
Option 1 — Visit a Jeweller
The most accurate way to determine your ring size is to visit a local jeweller and have your finger professionally measured.
Option 2 — Measure at Home
You’ll need:
- A thin strip of paper or non-stretch string
- A ruler (millimetres)
- A pen
Steps:
1. Wrap the paper or string around the base of your finger.
2. Mark where the ends meet.
3. Measure the length in millimetres — this is your finger’s circumference.
4. Use the chart below to find your ring size.

Tips for Accurate Sizing
- Measure your finger at the end of the day when it’s at its largest.
- Avoid measuring when your hands are cold, as fingers can be smaller.
- For wider bands, consider going up half a size for comfort.
- If between sizes, choose the larger size — resizing down is easier than resizing up.

Chain Length Guide
Choosing the right chain length ensures your necklace sits exactly where you want it — whether you prefer a close-fitting choker, a classic pendant drop, or a long, dramatic look.
Common Chain Lengths & How They Fit
(Based on average adult sizing — lengths may vary slightly depending on your body frame.)
| Length | Style Name | Where It Sits | Best For |
|---|---|---|---|
| 35–40 cm (14–16") | Choker | Snug around the neck | Layering, casual wear, high necklines |
| 42–45 cm (17–18") | Princess | Just below the collarbone | Everyday wear, pendants, most necklines |
| 50 cm (20") | Matinee | Above the bust | Office wear, elegant pendants |
| 60 cm (24") | Opera | Mid-bust or lower | Statement pieces, layering |
| 75–90 cm (30–36") | Rope | Waist length | Dramatic looks, layering doubled |
Tips for Choosing Your Chain Length
- For pendants: A 45–50 cm (18–20") chain is the most versatile and works with most necklines.
- For layering: Choose two or more lengths with at least 5 cm difference between them.
- For high necklines: Longer chains (50 cm+) create a balanced look.
- For open necklines: Shorter chains (40–45 cm) draw attention to the collarbone.
Measuring at Home
- Use a soft measuring tape around your neck at the point where you’d like your pendant or chain to sit.
- If you don’t have a tape, use string and measure it against a ruler.
