### Learn

Here is what I have learned, plus “calculators” for working with chainmaille, and links to other online resources. I am as interested in the math, science, and technique behind chain jewelry as I am in making chain jewelry.

## Chainmaille Aspect Ratios for Various Weaves

These are the ring specifications that I prefer when making various weaves. In the details below, I used the following acronyms:

AR = Aspect Ratio ID = Inner diameter GA = Gauge (in American Wire Gauge, AWG)

This list provides my preferred jump ring size for each weave, along with the aspect ratio. Of course, with the aide of the Aspect Ratio Calculator (below), you can change the chainmaille ring sizes and gauge and make your pieces just as nice.

WEAVE:  Preferred AR (sample ring details), sample with these details

• Tryzantine Aspect Ratio: 5.5 (4.5 mm ID, 20 GA)
• Box Chain Aspect Ratio: 4.5+ (4.5 mm ID, 18 GA) see sample
• Byzantine Aspect Ratio: 3.7 (3 mm ID, 20 GA) see sample
• Full Persian Aspect Ratio: 5.5 (4.5 mm ID, 20 GA) see sample
• Perfect Jens Pind Linkage (JPL) Aspect Ratio: 3.1 (2.5 mm ID, 20 GA; 3 mm, 18 GA) see sample
• Reverse Tao Flower Aspect Ratio: 7.4 (7.5 mm ID, 18 GA)
• Rondo a la Byzantine Aspect Ratio: 3.9 & 5.9 (4 mm & 6 mm ID, 18 GA) see sample
• Turkish Round Aspect Ratio: 3.9 (4 mm ID, 18 GA) see sample
• Viper Basket Aspect Ratio: 5.6 & 8.6 (4.5mm & 7.0 mm ID, 18 GA) see sample
• Candy Cane Cord-Dense: 5.6 (4.5 mm ID, 20 GA)
• Candy Cane Cord-Loose 6.2 (5.0 mm ID, 20 GA) see sample
• Half Persian 4 in 1 Aspect Ratio: 5.6 (4.5 mm ID, 20 GA) see sample

## Aspect Ratio Calculator

My Excel “calculator” for Inner Diameter (ID), Gauge (GA), and Aspect Ratio (AR). I use this every time I’m making a new piece. I created this calculator because I needed a way to ensure I used the right ring size and wire gauge for beautiful-looking chain. I hope you find it useful, too, as you work on your own projects.

What the calculator will do for you:

1. Enter the desired ID and GA, and the calculator will tell you what AR will result.
2. Enter the desired AR and GA, and the calculator will tell you what ring size to use.
3. Enter the desired AR and ID, and the calculator will tell you what GA you need. (This is the calculation I use most frequently.)

It also does the math for various measurement conversions, such as inch to mm, inch fraction to inch decimal, inch fraction to mm, troy ounce to regular ounce, and weight to length, and more.

The AR is the most important number to chainmaille. With the right AR, your pieces won’t be too loose or too tight. If the AR is too low, you might not be able to fit all the rings you need or the piece won’t be flexible. If it is too high (a sign of amateur craftsmanship), the rings will be floppy, and the chain won’t have a professional appearance.

Here’s what it looks like when opened (screen shot of the Excel file):

The calculator has a place for you to record desired ARs and chainmaille weave names so you can record and remember what AR you need. I added a few sample weaves and recommended ARs just to get you started.

## Wire Length Calculator

You have just made or received a piece of chainmaille jewelry, and you want to make another one. How much wire will you need? If you know the weight of the jewelry, this Excel worksheet will do the math and tell you the length of the wire in the jewelry.

Here is what it looks like:

To use this weight-to-length calculator:

1. Determine the type of wire: silver plate (or copper), sterling silver, or gold-fill
2. Enter the weight of the jewelry in regular ounces (not troy ounces)
3. Enter the wire gauge using the pull-down menu: 16, 18, 19, 20, 21, 22, 24

The Benefit of Using This Calculator: When you do these three steps, the calculator will tell you the length of wire in the jewelry. Now you know how much wire you will need for your next project.
