Size Guide for Rings

Finding the perfect ring is an important part of the journey towards a lifelong commitment. To help you choose the right size, we've put together a handy guide with different methods for measuring your ring size.

How do I measure my ring size?

Method 1: Use an existing ring

If you already have a ring that fits the finger you will wear your engagement ring on, you can use it to find the right size:

  1. Measure the diameter (inside of the ring) with a ruler in millimeters.
  2. Compare the measurement with our size chart below.

Method 2: Measure your finger

If you don't have a suitable ring, you can measure your finger directly:

  1. Take a thin strip of paper or a piece of string.
  2. Wrap it around the finger where the ring will sit – neither too loose nor too tight.
  3. Mark where the ends meet and measure the length in millimeters.
  4. Compare the circumference with our size chart.

  1. Stand in front of a mirror and place a soft measuring tape around your neck.
  2. Decide how far down you want the necklace to hang.
  3. Read the measurement where the measuring tape meets and choose the closest suitable necklace length from our table.

Method 2: Use a string or a strip of paper

  2. Mark where the ends meet and then measure the string with a ruler.
  3. Compare the measurement with our size chart below.

Size chart for Necklaces

Please note that the size chart below is a general reference and that the fit may vary depending on individual preferences and neck circumference.

Necklace length (cm)

How it fits and what it is suitable for

35 – 40 cm (Choker)

Fits snugly around the neck, perfect for a modern and minimalist look. Best suited for thin chains and necklaces.

42 – 45 cm (Princess length)

Located right at the collarbone and is the most common length. Goes well with all types of outfits.

50 – 55 cm (Matinée)

Falls just below the collarbone, perfect for creating an elegant look for everyday wear and parties.

60 – 65 cm (Opera)

A longer necklace that reaches across the chest and gives a sophisticated feel.

70 – 90 cm (Long necklace)

Can be worn long or wrapped twice around the neck for a layered effect.

100+ cm (Rope)

Extra long necklace that can be styled in many different ways and gives a dramatic look.


How to choose the right necklace length

  • Shorter necklaces (35–45 cm) are best suited for a narrow neck and give an elegant, close-fitting look.

  • Medium-length necklaces (50–55 cm) are a versatile choice and suit most face shapes and outfits.

  • Longer necklaces (60 cm and up) create a more dramatic and elegant look, perfect for wearing over high necklines or polo shirts.

Tips for finding the right size

✔ If in doubt, choose an adjustable length for flexibility.
✔ Consider your face shape – longer necklaces can elongate your face, while shorter necklaces can accentuate your jawline.
✔ Combine different lengths for a trendy layered style.

Choose the right fit

  • Tight fit – For those who want a tighter bracelet that sits close to the skin, we recommend that you choose the smaller option from the table in relation to your wrist circumference.

  • Standard fit – For the most common fit that provides adequate freedom of movement, we usually recommend that the bracelet be between 1-2 cm larger than your wrist circumference.

  • Comfortable fit – For a little extra room and a more relaxed feel, we recommend a bracelet that is about 3 cm longer in circumference than your wrist.

Frequently asked questions

How do I know if I should choose a larger size?
If you prefer a looser fit or if the bracelet has a rigid design without adjustment, we recommend choosing a bracelet that is at least 1 cm larger than your wrist circumference.

Can I adjust the size of the bracelet?
Some of our bracelets have adjustable chains or flexible materials for a customizable fit. Please contact us if you are unsure which models can be adjusted.
