How to Determine Your Ring Size?

Method 1: Measure the Diameter (for the meticulous)

For this, take a ring that fits the finger you plan to wear your new ring on and a ruler.

Preferably choose a band
to make measuring easier

Place the ring on your ruler to
measure the diameter

Refer to the measurement in the conversion table:

Ring Diameter	Europe	US	UK
14 mm	44	3	f1/2
14.6 mm	46	3.75	h
15.3 mm	48	4.5	h1/2 - i/2
16 mm	50	5	j-k
16.5 mm	52	6	l - l1/2
17.2 mm	54	7	o - p
17.8 mm	56	7.5	p1/2 - q1/2
18.5 mm	58	8.5	p1/2 - q1/2
19 mm	60	9	r1/2 - s

For this, take a fabric or paper tape, a ruler, and a pencil.

Ideally, take your measurements in a temperate place to avoid temperature fluctuations that can affect finger size.

Start by marking a first point on the tape

Wrap the tape around your finger

Mark a second point opposite the first

Measure the distance between your two marks
