🚩 I strongly recommend you get your ring size from your local jewellery store ( it's free). If you don't have access or time for that, here's a guide.

CUFF

To find out your cuff size, measure your wrist using a tape measure or a printable ruler easily found on the internet (make sure your printer is properly calibrated). If you have a thread, you can wrap it around your wrist then mark the join of the thread with a line, finally measure the dimension between the two lines.
