1. Measure your neck

Two ways to measure your neck thickness — choose whichever suits the tools you have.

Option 1 · Caliper

15 cm (6") caliper

A mirror

Watch: measuring with a caliper

A 15 cm (6") plastic caliper costs about $5 on Amazon.

Stand in front of a mirror.
Use the caliper to measure the thickness at the mid-length of the back of your neck.
Bring the caliper forward and write down the measurement.
Match it to the chart above.

Option 2 · Ruler & pegs

30 cm / 15" ruler

2 clothes pegs

A mirror

Watch: measuring with a ruler & pegs

Correct peg placement

Example: first peg at 10 cm, second ends at 19 cm → 9 cm (≈3.5") = Medium.

Clip the first peg at an even mark — e.g. 10 cm (4") — and the second at 25 cm (10").
Stand in front of a mirror and hold the ruler behind your neck, roughly at its mid-length, with one peg touching your neck.
Slide the other peg left or right until it touches the opposite side.
Check in the mirror that both pegs are straight and level, not angled.
Bring the ruler forward and write down the distance between the pegs.

2. Check your ear size

If your ears are slightly larger than the dimensions shown (+3 mm / +0.12"), they'll still fit in the Serenade, though they may fold slightly in some areas. Some people don't mind this; others prefer to avoid it — so consider your preference.
