What's Your Ring Size?
Ring Sizer

Note: Your fingers can swell in size when they're warm. Therefore it's best to take measurements when your hands are warm, typically late in the day.
First, grab a short piece of string or paper, and wrap it around your finger, exactly where your ring would be.
Make sure it's wrapped comfortably - not too tight!
Mark or cut the point where the string/paper begins to overlap.
Measure the length...

..and voilà! Now you can use this handy chart below to match your measurement to your closest ring size:
