Necklace Length Guide: How to Choose Between 12 and 24 Inches

Every Opiona necklace comes in seven chain lengths. Here is how each one sits, which length suits which neckline, and how to measure at home before you order.

Choosing a chain length is the one decision that changes how a pendant looks more than anything else. The same name necklace can read as a delicate choker or a relaxed everyday piece depending on a few inches of chain. Every necklace in our necklace collection can be ordered in seven lengths — 12, 14, 16, 18, 20, 22 and 24 inches — or as a pendant only if you already have a chain you love. This guide explains where each length falls and how to pick the right one.

Where each length sits

Lengths below are measured end to end, clasp included, and describe a typical adult neck. A slimmer or wider neck moves the pendant up or down by roughly an inch.

LengthWhere it fallsBest for
12 inSnug around the base of the neckChildren and very fitted choker looks
14 inJust above the collarboneChoker style on adults, teens
16 inOn the collarboneSmall name and initial pendants, open necklines
18 inJust below the collarboneThe most popular everyday length for women
20 inA few inches below the collarboneCrew necks, layering under an 18" chain, men's pendants
22 inAt or just above the bust lineLarger pendants, wearing over knitwear
24 inAt the bust line or belowLong, relaxed looks and men's chains

The quick answer: start with 18 inches

If you are buying a gift and do not know the recipient's preference, 18 inches is the safest choice. It sits just below the collarbone on most adults, shows a pendant clearly with almost any neckline, and works on its own or as the shortest strand in a layered set. It is also the length most of our customers choose for custom name necklaces.

Match the length to the neckline

V-necks and scoop necks

An 18 or 20 inch chain lets the pendant follow the shape of the neckline and land in the open space, which flatters a V-neck in particular.

Crew necks and high necklines

Go either short (14–16 in) so the necklace sits above the fabric, or long (22–24 in) so it rests on top of it. In-between lengths tend to disappear under the collar.

Off-the-shoulder and strapless

Shorter chains of 14–16 inches frame the collarbone and keep the look clean.

Consider the size of the pendant

Small, dainty pendants such as initials or a single star look best close to the face on 16–18 inch chains. Wider designs — a full name in script, a pet silhouette or a statement charm — have more presence on 18–20 inch chains, where they have room to hang flat.

How to measure at home

  1. Take a necklace you already wear and like, lay it flat and measure from the end of the clasp to the end of the ring.
  2. No necklace to measure? Wrap a piece of string or a phone charging cable around your neck, let it fall where you want the pendant to sit, mark the spot and measure the length with a ruler.
  3. Add about two inches to your neck measurement as a starting point for a comfortable, non-choker fit.

Layering necklaces

For a layered look, keep at least two inches between strands so pendants do not tangle: 16 + 18 + 20 inches is a classic trio. Mixing finishes works well too — a sterling silver chain next to an 18K gold plated one gives a modern, intentional contrast. Browse our minimalist necklaces for pieces that stack easily.

Lengths for children and men

For young children a 12 or 14 inch chain keeps the pendant from swinging into food and play; always supervise small children wearing jewelry. Men usually prefer 20–24 inches, where a pendant sits mid-chest rather than at the collarbone.

Still not sure?

Choose 18 inches for a gift, or tell us about the recipient through our contact page and we will help you pick. Every piece is made to order in our studio, so the length you select is the length we make.
