A simple utility to keep track of common aspect ratios for various chainmail patterns. Also includes a calculator that can calculate the the aspect ratio based on wire and inner diameters -- or, more importantly, it will allow you to determine what gauge wire and what inner diameter to use to get a specific ratio!
This is a tool I created for myself that I hope you find useful. If you have any issues or suggestions for improvement, I'd be happy to hear them!
