Why Ring Size Matters?

Before we dive into the how, let’s understand the why. Ring size matters because it’s the difference between a cherished piece of jewelry and an uncomfortable accessory that you can’t wear.

A ring that is too tight can even block blood flowing through the finger and can cause blueness and numbness. On the other hand, a ring that is too loose can slip off at any moment and you would be at a financial loss as well as emotional loss.

Hence, a properly sized ring stays in place, looks elegant, and avoids the annoyance of slipping or feeling too tight.

More Ways to Measure Ring Size Accurately

While online ring sizer tools are incredibly convenient, there are alternative methods to find ring size:

  1. String or Paper Strip Ring Sizing
    This is a very common do-it-yourself way of finding your size. Just wrap a string or strip of paper around your finger. Make sure it snugs to your finger and then mark the overlap with a marker. Now, unwrap the string or paper string and measure the length. This length is the circumference of the ring that will fit your finger. Use the ring size converter to convert circumference to ring size in one click.
