Ring size Guide

A ring should not be too tight or too mobile.

To determine the perfect size of a ring you must take the ring and place it on a flat surface through a horizontal ruler is necessary to measure the inner diameter (the largest distance between the inner edges), as specified in figure once in possession of the size in centimeters just compare the value with the scale below.

Dimension in mm/Ring Measurement

14.00 mm = 4
14.30 mm = 5
14.50 mm = 6
15.00 mm = 7
15.30 mm = size 8
15.50 mm = 9
16.00 mm = 10
16.30 mm = 11
16.50 mm = 12
17.00 mm = 13
17.30 mm = size 14
17.50 mm = 15
17.70 mm = 16
18.00 mm = 17
18.50 mm = size 18
18.80 mm = 19
19.00 mm = 20
19.50 mm = 21
19.70 mm = 22
20.00 mm = 23
20.50 mm = 24
20.80 mm = 25
21.00 mm = 26
21.30 mm = 27
21.50 mm = 28

 

We can determine the size of a ring in this way:

Roll a strip of paper or a piece of plastic or other (just not elastic) around the larger phalanx of the finger.
Make a mark at the point where the two ends of the strip of paper/plastic etc. they meet.
Measures the portion of the paper strip so selected with a ruler or a tape and make a note of the mm.
The circumference in millimeters so measured will correspond to your size (see schedule below).
Note: If your size is between two numbers on the scale, take note of the upper size anyway.
The following schedule also indicates International size conversions.
