Finding the ideal ring size can be quite tricky, especially if you’re shopping for rings online. Your ring should fit your finger comfortably and fit snug enough so that it will not fall off easily, but at the same time loose enough to have it slide over your knuckle with some resistance. Here are a few easy methods which you may try to make sure your ring fits perfectly every time!
Measure Your Finger Using A Piece of Paper.
You’ll need a pen, ruler, paper, and scissors.
1. Cut a strip of paper evenly and wrap it around the base of the finger that you want to measure
2. Make sure the paper feels snug against your skin to ensure the perfect fit.
3. Mark where the paper meets.
4. Place the paper against a ruler and measure the length of your finger’s circumference.
5. Use the ring size conversion chart to find your ideal size.
6. Consider your knuckle; Repeat the process around your knuckle if your knuckle is larger than the base of your finger. Compare the two sizes and consider ordering half a size bigger than what your finger alone indicates to slide the ring over your knuckles into the right place.
** You may follow the steps above using a measuring tape for more accurate measurements.
