Sometimes we look for tools that don't exist. We may find something close and either accept or modify it. Or go all out and create the better mousetrap. The challenge and need to do it without compromise spur many inventors.

Most of my programming (coding) is just for me. It makes my job and endeavors much easier. Commercially there may be an application for some of them - certainly my skills are useful to a handful - but that's not how it's gone down.

With jewelry and chain making, eliminating the guesswork regarding materials, quantities, and amounts saves time and money. Silver and gold are expensive and it's wasteful to make more rings, wire, or sheet than required. I made programs that figure all that out.

To help the cause, I created the most comprehensive aspect ratio charts which have been recently upgraded with more sizes. They include the full complement of usable AWG and SWG gauges along with millimeters in 0.1mm increments plus the common drawplate sizes less than 1.0mm. Ring sizes for SAE have 1/64" increments and millimeters, 0.5mm increments.

Having access to color-coded aspect ratio charts wasn't efficient or useful for all situations. Lots of back-and-forth between tables, scrolling up and down, sometimes doing additional calculations, etc. They left a void.

I decided to post my aspect ratio calculator online since other ones are, quite honestly, pathetic: sloppy, restrictive, too much effort, not self-sufficient. Mine is the best one. Yeah, everyone "thinks" their whatever is the best but I'm not being delusional. It also computes wire length and has pre-loaded metal densities for common metals and alloys to estimate weight.

Something was missing, or maybe too much was there. I wanted the crucial information without fluff, scavenger hunting, or repeatedly entering new values. Thus, I made the ultimate jump ring size finder calculator. There is nothing remotely similar to this all-encompassing game-changer.

I showed it to a friend and they were, naturally, unimpressed. Agreed...for the average person it is meaningless. However, it will be biblical for the small number needing such information. Basically, if you can't figure it out with one of these tools you are doing something wrong!

Anyway, the aspect ratio calculator has only one main formula - inner diameter divided by wire diameter - so it's not rocket science. They say it's the journey, not the destination, and I took a circuitous route with decidedly more options and math. Users will appreciate its thorough and elegant simplicity.

The jump ring size finder has countless calculations and thousands of lines of code. It is bona fide intellectual property worth protecting and processed server-side for that reason. Perhaps there will be modifications in the future though it's fairly complete, functional, and free to use.
