Buying a gold chain online without trying it on is where most people get the size wrong. The chain arrives, goes on, and sits two inches higher or lower than expected. It does not look bad exactly; it just does not look the way it did in the picture.
Length is the single decision that changes everything about how a chain reads on the body. The same chain in the same style at 16 inches and at 22 inches is practically two different pieces. One sits close to the throat, the other drops below the collarbone.
Manna Jewellers in Birmingham's Jewellery Quarter stocks gold chains across all standard lengths in 9ct and 18ct yellow, white, and rose gold. Browse the gold chains collection or visit the showroom to try lengths in person before you commit.
Chain lengths are measured in inches, end-to-end, including the clasp.
16 inches sits at the base of the neck, close to a choker position.
18 inches is the most popular chain length for women, sitting at or just above the collarbone.
20 inches is the crossover length; it works for both men and women, depending on the frame.
22 to 24 inches is the standard range for men's chain sizes, sitting on or below the chest.
Add 2 inches to your neck measurement to get a comfortable starting chain length.
The chain's size also affects the right length: heavier chains wear best with longer drops.
Use a soft tape measure or a piece of string. Wrap it around the base of your neck where you want the chain to sit, not at the very top of your throat, but lower, at the position where the chain would actually lie. Note the measurement and add 2 inches for a comfortable fit.
If you want a chain that sits lower, add more. For a pendant chain, add enough length so the pendant lands wherever you want on your chest. This is the most reliable way to get the chain size right before buying.

All chain lengths at Manna Jewellers are measured end to end with the clasp included.
For most women, 16 to 20 inches is enough for everyday wear. Within that range, there are meaningfully different results.
A 16-inch chain sits just above the collarbone, close to the base of the neck. It works well with lower necklines where the chain needs to stay visible above the clothing. It has a choker-adjacent feel without being as close-fitting as a true choker.
18 inches is the most popular chain length for women in the UK. It falls at or just above the collarbone on most frames and is the standard for lockets, pendants, and plain everyday chains. Buying a chain as a gift without knowing the recipient's preference? 18 inches is the safest starting point.
20 inches sits below the collarbone and gives a little more drop. It works well for women with longer necks or for anyone who wants a chain that stays visible over a higher neckline.
Men's chain lengths generally start at 20 inches because male neck and chest proportions need more length for a chain to sit in a balanced position.
A 20-inch chain on a man sits just at or below the collarbone. It is subtle and understated, particularly suited to slim chains or to wearing under a shirt, where only the bottom of the chain shows at the collar.
22 inches is the most common length for men's everyday chains. It clears the collar and sits on the chest, making it visible when wearing an open-collar shirt or a crew neck. For a pendant, 22 inches places most pieces at a comfortable position on the upper chest.
24 inches gives a more relaxed drop. Heavier chains in curb, rope, or Franco styles wear best at this length because the weight benefits from a longer drop rather than sitting bunched at the collarbone. Taller men or those who prefer a more prominent look often choose 26 inches or longer.
It does, more than most people expect.
A fine chain at 1mm or under can look lost at longer lengths because there is not enough visual mass to justify the drop. Fine chains tend to read better at 16 to 20 inches. A heavier chain at 3mm and above benefits from a slightly longer length. A thick curb chain at 16 inches can look cramped on a wider neck. The same chain at 22 or 24 inches has room to settle naturally.
As a rough guide: fine chains wear best at 16 to 20 inches, medium chains at 18 to 22 inches, and heavier chains at 22 inches and above.
Expert tip: when buying goods online, you have the right to return items that do not match their description, including if a chain length differs from what was advertised. For chain lengths specifically, this is worth knowing before you order. At Manna Jewellers, chains are available to try in the Jewellery Quarter showroom, which removes the guesswork before you commit to a size.
For layering to look deliberate rather than accidental, each chain needs its own zone on the body. Separate layers by at least two inches.
A 16-inch and an 18-inch chain worn together sit almost identically and compete visually. A 16-inch, an 18-inch, and a 22-inch chain each occupy a different position and create the layered effect intentionally. For men, a combination of 20, 22, and 26 inches gives clear separation between each chain.
Mixing chain styles alongside different lengths adds further distinction. A fine trace chain at 16 inches under a Figaro at 20 inches under a heavier rope at 24 inches gives three separate visual layers with no overlap.
18 inches (45cm) is the most common chain length for women, sitting at or just above the collarbone and working with most necklines. A 16-inch chain sits higher at the base of the neck. A 20-inch chain drops slightly below the collarbone. For a gift, 18 inches is the safest choice if you do not know the recipient's preference.
The standard range for men runs from 20 to 24 inches. A 20-inch chain sits just below the collarbone, 22 inches rests on the chest and is the most popular everyday length, and 24 inches gives a more relaxed drop suited to heavier chains and pendant wear. Taller men or those who prefer a bolder look often choose 26 inches or longer.
Measure around the base of your neck with a tape measure or a piece of string. Add two inches to that measurement for a comfortable fit. Compare the total against a chain length chart to find the nearest standard size. If you want the chain to sit lower on the body, add more length. If you want it closer to the neck, add less.
For a pendant sitting at the collarbone, 18 inches works for most women and 20 to 22 inches for most men. For a pendant hanging at chest level, go for 20 to 22 inches for women and 22 to 24 inches for men. A heavier pendant benefits from a slightly shorter chain so it does not pull down uncomfortably.
Separate each chain by at least two inches so each one occupies its own visual zone. A combination of 16, 18, and 22 inches works well for women. For men, 20, 22, and 26 inches give clear separation. Mixing different chain styles alongside different lengths gives each layer its own identity and prevents the chains from visually merging.
