How Long Is a 16 Inch Chain? | The Actual Answer

For the full breakdown, see our best 16 Inch Gold Chain guide.

Wondering how long a 16 inch chain really is? The answer splits into two very different worlds. For jewelry, 16 inches is a standard necklace length that sits near the collarbone. For a chainsaw, “16-inch” refers to the bar it fits, not the chain’s own length — and matching pitch, gauge, and drive links matters far more.

16-Inch Necklace Length: Where Does It Fall?

A 16-inch necklace measures about 40.6 cm from end to end, including the clasp. Most jewelry retailers describe this length as choker or collarbone length for women with average neck sizes.

Where exactly it rests depends on your neck size and build:

• Base of the neck — on smaller or average frames, a 16-inch chain sits snugly at the throat.
• Just above the collarbone — on most women, this is the typical resting point.
• At the collarbone — on taller or larger frames, it settles right on the bone.

Men’s sizing guides also list 16 inches as choker length, though it fits more snugly on larger neck sizes. If you’re shopping for a gift, measuring the recipient’s neck and adding about 2 inches gives a more comfortable fit.

16-Inch Chainsaw Chain: What the Size Really Means

For chainsaws, a “16-inch chain” is one designed to fit a 16-inch guide bar — the chain’s physical length is not the defining spec. What actually matters are three numbers: pitch, gauge, and drive-link count.

Chains with the same nominal bar length are not interchangeable unless those specs match. Oregon’s replacement guide is explicit: check the bar, the old chain, or the owner’s manual for the required pitch, gauge, and drive links before buying. Common 16-inch chains showcase why this matters:

The differences are not academic. Putting a 56-drive-link chain on a saw built for 52 links will not fit, and running mismatched pitch or gauge is a safety risk. The single most common mistake buyers make is assuming “16-inch” alone is enough — it is not, and using the wrong chain can be dangerous.

16 Inches in Other Units (Plus an Odd One)

If you’re converting for sizing, here’s the straightforward math: 16 inches equals 40.64 cm, which most jewelry guides round to 40 cm or 40–41 cm for simplicity. For the curious, the surveyor’s unit known as a “chain” converts differently: 16 chains equals 12,672 inches, and 16 inches equals about 0.0202 chain — an obscure conversion that rarely comes up outside land surveying.

FAQs

Is a 16-inch necklace too short for most women?

No. A 16-inch necklace is one of the most common lengths sold and sits at or just above the collarbone for average-sized women. It reads as a choker-style piece. On women with larger necks or broader shoulders, it may feel snug, and many prefer an 18-inch length for a looser drape.

Will any 16-inch chain fit my chainsaw?

No. The “16-inch” label only means the chain is intended for a 16-inch guide bar. You must also match the pitch, gauge, and drive-link count to your specific saw model. A chain that fits one 16-inch saw may not fit another, so always verify the specs from the bar, the old chain, or the owner’s manual.

How do I measure necklace length correctly?

Lay the necklace flat and measure the full length from one end of the clasp to the other, including the clasp itself. That total is the listed size. To choose a comfortable fit, measure your neck circumference and add roughly 2 inches for a relaxed fit or 1 inch for a snug choker feel.
