How to Measure for a Necklace
When choosing a necklace length, consider the style of the piece, the neckline you plan to wear it with, and whether you prefer a close, classic, or more relaxed fit.
To find your ideal necklace length, wrap a flexible measuring tape around your neck and adjust it to where you would like the necklace to rest. If you do not have a measuring tape, use a piece of string or ribbon, mark the length, and measure it with a ruler.

14-Inch Necklace
- A 14-inch necklace typically fits closely around the neck, creating a choker-style silhouette. This length is ideal for a sleek, modern look and works beautifully when worn alone or layered with longer necklaces.
16-Inch Necklace
- A 16-inch necklace usually rests at the base of the neck. This length offers a refined, elegant fit and is often chosen for shorter diamond necklaces, delicate chains, and petite pendants.
18-Inch Necklace
- An 18-inch necklace is one of the most classic and versatile lengths. It typically falls near the collarbone, making it a beautiful choice for diamond pendants, everyday gold chains, and timeless fine jewelry necklaces. This length is also a popular choice for gifting because it flatters a wide range of necklines and personal styles.
20-Inch Necklace
- A 20-inch necklace sits slightly below the collarbone, offering a relaxed yet polished look. This length is ideal for larger pendants, statement diamond necklaces, or anyone who prefers a little more length and movement.
22-Inch Necklace
- A 22-inch necklace creates a more elongated silhouette and usually falls lower on the neckline. This length pairs beautifully with open necklines and can add a graceful, lengthening effect to the overall look.
24-Inch Necklace
- A 24-inch necklace offers a longer, more dramatic fit. It typically rests at or above the upper chest and is ideal for layering, statement styling, or creating a more effortless, elongated look.
Diamond Tennis Necklace Sizing
Diamond tennis necklaces are designed to sit beautifully around the neckline with a smooth, continuous line of brilliance. The ideal length depends on how close you want the necklace to sit and how much drape you prefer.
A 15- to 16-inch tennis necklace creates a closer, more refined fit around the base of the neck. A 17-inch tennis necklace offers a classic, elegant placement that sits slightly lower while still feeling polished and secure. An 18-inch tennis necklace provides a more relaxed drape and is a timeless option for both everyday wear and special occasions.
A properly fitted diamond tennis necklace should rest comfortably against the neckline without feeling tight, twisting excessively, or shifting too much as you move.
Pendant Necklace Sizing
Pendant necklaces are often selected based on where you want the pendant to fall. A shorter length, such as 16 inches, keeps the pendant close to the base of the neck for a delicate, refined look. An 18-inch chain places the pendant near the collarbone, creating one of the most classic and universally flattering placements.
For larger pendants or statement diamond necklaces, a 20-inch chain may offer a more balanced look by allowing the pendant to rest slightly lower on the neckline.
Layering Necklace Lengths
Layering necklaces is a beautiful way to create dimension, texture, and personal style. For the most balanced layered look, choose necklaces with at least a 2-inch difference between each length.
A classic layered combination may include a 16-inch chain, an 18-inch pendant necklace, and a 20-inch chain or diamond necklace. This spacing allows each piece to be seen clearly while creating an effortless, elegant arrangement.
When layering fine jewelry, consider mixing different textures, diamond accents, and chain styles while keeping the overall look refined and cohesive.
Choosing the Right Necklace Length
The best necklace length depends on your clothing neckline, styling preference, and the design of the piece. A shorter necklace creates a polished, close-to-the-neck look, while a longer necklace adds softness, movement, and an elongated silhouette.
Diamond pendants, tennis necklaces, gold chains, and statement necklaces each sit differently, so it is important to choose a length that complements both the jewelry and the person wearing it.
If you are purchasing a necklace as a gift, 18 inches is one of the most popular and versatile necklace lengths. It offers a timeless fit that works beautifully with a wide range of styles.
