MEASURING YOUR FINGER AT HOME
Sizing yourself for a ring at home is easier than you might think. There are multiples ways to go about determining your ring size so I'll walk you through a couple. The easiest way to size yourself is by using a flexible tape measure that you might find in a sewing kit. Simply wrap the tape measure around the finger you want the ring for and match it up with the ring size measurement chart I have provided below. If you don't have a flexible measuring device for ring sizing, you can take a piece of string or yarn and wrap it around your finger then measure that length with a ruler.

EXTRA TIPS FOR MEASURING YOUR FINGER
Make sure your hand isn't too warm. You want to get an accurate ring sizing, so make sure your hands aren't swollen when determining ring size.
Wrap your string or tape measure snugly around your finger. It shouldn't be too loose, but also not too tight.
