Ring Sizing Chart

Ring Sizing Chart

CLICK HERE TO DOWNLOAD A PDF OF THIS CHART

To properly size a ring, you need to know the thickness of your material and the desired ring size. From there you can use this chart to intersect the two (from the columns and rows) to determine how long you need to cut your metal (in mm).

For example, if you want a size 6 ring and you are using 18 gauge material, you need to cut your material to 54.7mm long.

If you don't have a chart like this, you'll need to do some math. You will need to know the inner diameter of your desired ring size and the thickness of your metal. Then use this formula -

(RING INNER DIAMETER + THICKNESS OF METAL) X 3.14 (Pi!) 

You never thought you would use Pi in your life did ya? Yeah, it's just easier to use the below chart, you're welcome!
