Here is a basic DIY option to measure your ring size.
For a more accurate measurement, I have a ring sizer tool that you can purchase from my shop for $5. I will include a $5 coupon code that you can use towards your next purchase. And you can keep the ring sizer tool for re-use.

RINGS
DIY measure your fingers at home by following these steps:
1. Cut a strip of paper that will wrap around the circumference of your finger
2. Wrap the paper around your finger, make sure it's nice and comfortably tight and mark the spot where it meets
3. Measure the distance with a ruler (in mm); this will be your finger's circumference
