Cross Chain Length: How to Pick 16, 18 or 20 Inches
TL;DR – 16 inches sits at the collarbone, 18 inches just below it (the safe default for most people), 20 inches lands on the upper chest and 22 to 24 inches drops to the sternum. Measure your neck, add 2 inches, then match the length to your cross size and your neckline. When in doubt, go 18 inches with a 2 inch extender, and layer from there.
You found the cross you love. Then you hit the dropdown: 16 inches, 18 inches, 20 inches, and a chain length you have never thought about in your life. Twenty minutes later you are still guessing, and the only thing you are sure of is that you do not want to order twice.
Here is the good news: chain length is the easiest part of buying a cross to get right, once you know a few simple rules. This guide walks you through what each standard length actually looks like on a real body, how to measure yourself in under a minute, and how to match the length to the size of your cross and the way you dress. If you want to browse while you read, our cross necklace collection lists the available length for every single piece.
Why Chain Length Changes the Whole Look
The same cross on two different chains is basically two different pieces of jewelry. A short chain makes a small cross feel crisp and intentional, like part of your outfit. A long chain turns the same cross into a statement that shows up over a sweater or a hoodie. Neither is better. They just do different jobs.
Length also changes how people read your cross. Sitting right at the collarbone, it reads as a quiet everyday detail. Dropped toward the sternum, it becomes the first thing someone notices. And there is a practical side too: the wrong length can make a cross flip, hide under a collar, or poke out of a neckline in a way that never quite looks right.
Where 16 to 24 inches actually sits, side by side :
The Standard Lengths, Explained One by One
Most cross chains are sold in a handful of standard lengths. Here is what each one really does once it is on you.
16 Inches: The Collarbone Cut
Sixteen inches sits right at the base of the neck on most adults. It is the classic length for a small, delicate cross, and it stays put: no flipping, no sliding under a shirt. This is the length people reach for when they want their cross to feel like a second skin, worn every day and rarely taken off.
The tradeoff is fit. If your neck measures 15 inches or more, a 16 inch chain can feel snug, and a chunky cross will not have room to lay flat. It also disappears under most crew necks, which makes it a poor choice if you actually want the cross visible.
18 Inches: The Default for a Reason
Eighteen inches is the most popular chain length in the United States, and it is the length we recommend when someone asks us for a single, safe answer. On most people it lands an inch or two below the collarbone, which means the cross sits on skin with a crew neck and peeks out of one with a slightly lower neckline. Small and medium crosses look their best here.
It also plays well with layering: an 18 inch chain is usually the shortest visible layer, with a 20 or 24 inch piece under it. If you are buying a cross as a gift and you do not know the recipient’s measurements, 18 inches is the length that gets the fewest returns.

20 Inches: The Sweet Spot for Medium Crosses
Twenty inches drops the cross onto the upper chest. This is where medium sized crosses start to feel properly showcased, and it is the length that works with the widest range of necklines, from crew necks to V necks to buttoned shirts worn open. On a slim build it reads elegant; on a broader build it keeps the cross visible instead of hiding it up top.
It is also the first length where layering really starts to shine, sitting just under a typical 18 inch chain without tangling with it, as long as the two chains have different weights.
22 to 24 Inches: Long, Relaxed, Statement
At 22 to 24 inches the cross lands around the sternum. This is the length for bigger crosses, for pieces with real detail you want people to actually see, and for anyone who likes that relaxed, slightly retro drape over a tee or a hoodie. It is also the length that flatters rounder faces and fuller necks, because it creates a longer vertical line.
Longer chains do move more. If you are active, work at a desk, or lean over a lot, a 24 inch chain will swing forward now and then. A heavier cross actually helps here: weight keeps it lying flat.
How to Measure Your Neck in 60 Seconds
Skipping this step is how people end up with a chain that is 2 inches too short. All you need is a piece of string, a tape measure, or an existing chain that fits you well.
The Method
- Wrap the string or tape around the base of your neck, where a collar would normally sit.
- Mark where it meets, then lay it flat and measure that distance in inches. That is your neck measurement.
- Add 2 inches for a chain that sits at the collarbone with a little breathing room, or 4 inches if you want it just below.
- Round to the nearest standard length: 16, 18, 20, 22 or 24 inches.
That is it. A 15 inch neck with 2 inches added gives you an 18 inch chain, which is exactly why 18 is the default. If you already own a chain you love, just measure it end to end, clasp closed, and match that number.
One Rule People Forget
The cross itself takes up room. A cross that is 1.5 inches tall will hang about 1.5 inches below where the chain rests, so a cross on an 18 inch chain visually ends up around 19.5 inches on you. With a big statement cross, you may want to go one length shorter than your measurement so the whole piece stays where you want it.
Matching the Length to Your Cross and Your Wardrobe
Measurements get you in the right zone. A few extra checks make the choice feel tailored.
Size Your Chain to Your Cross
Small crosses, under an inch, look best on 16 to 18 inch chains where they read as a fine detail. Medium crosses, one to two inches, are happiest at 18 to 20 inches, where there is enough space around them. Large crosses, over two inches, want 20 to 24 inches so they have room to hang without crowding the neckline.
Chain weight matters just as much as length. A fine 1mm cable chain and a heavy box chain at the same length behave very differently: the fine one stays light and moves with you, the heavy one holds its line and keeps a bigger cross sitting straight.
Think About Necklines
Crew neck: 18 or 20 inches, so the cross clears the collar. V neck and button downs: 20 to 24 inches, following the line of the opening. Turtlenecks and high collars: 24 inches, or skip it. Hoodies and oversized knits: 24 inches, where the cross stays visible instead of vanishing into the fabric.
Layering Without the Knot
The simple rule: keep at least 2 inches between layers, and vary the chain styles. An 18 inch fine cable chain with a 22 inch box chain sits cleanly, because the different weights keep them from twisting together. Two chains of the same length and the same thickness will tangle by lunchtime, every time.

5 Length Mistakes That Are Easy to Fix
After helping hundreds of people find their fit, these are the five mistakes we see the most.
- Buying 16 inches without measuring. It is the length that fits the fewest necks comfortably. Measure first.
- Ignoring the height of the cross. A 2 inch cross on a 16 inch chain hangs like a 18 inch piece. Factor the cross in, not just the chain.
- Matching length to a neckline you rarely wear. If your closet is 80 percent crew necks and hoodies, a 24 inch chain will spend most of its life invisible.
- Forgetting the extender. A 2 inch extender turns one chain into two lengths for a few dollars. It is the cheapest insurance in jewelry.
- Ordering a gift chain in your own size. The recipient’s neck is not yours. When gifting, 18 inches with an extender is the choice that fits almost everyone.
