Printable ring size chart

One A4 page, drawn at true size: a circle for every South African size from A to Z, a strip to cut out and wrap around the finger, and the chart in millimetres. Print it at 100% — not “fit to page” — and check the ruler measures 50 mm.

South African ring size chart

www.moissanite.co.za

Print at 100% (“actual size”). Turn off “fit to page” or “scale to fit” in the print dialog.
Check the ruler: it should measure exactly 50 mm. If it doesn't, the chart is scaled — print again.
Lay a ring that fits on the circles. The size is the circle whose line sits just inside the band. Between two? Choose the larger.

No ring? Cut out the strip

Cut along the dashes. Wrap it snugly around the base of the finger, printed side out, and read the letter where the start line ▶ meets the strip. Check it slides over the knuckle.
