New online bike geometry calculator
Sometimes I need to record and compare bike fits or frame geometries. Previously I've used a bike CAD software for that, but it's a bit overkill, so I've made an online bike geometry calculator which you run directly in the web browser. Perhaps others may find useful too so I thought I'd share it.
There's a foldout help panel with complete documentation as well as a step-by-step workflow to measure and make a geometry chart of a real bike you have, but you can also enter manufacturer's geometry diagrams. One use case is to enter the bike you have and like, and then from a geometry chart enter a bike you consider buying to see which frame size you need.

Very nice, can't wait to try it.

Very cool! There is a lot going on, but I will admit I have never looked quite that far into geometry.
I will be tucking this back into my archive of cool things that do in fact exist.

It's pretty niche, and I guess the main thing to figure out is what to use it for :-).
At least one of my bikes don't have geometry charts available from the manufacturer, so there I've used the measurement feature to record the geometry. Some manufacturers provide quite poor charts too, and in those cases one can often use the calculator to fill out more. Knowing the trail for example is nice to get a sense of how the steering behaves.
Then with my current bikes entered I can fantasize about which bikes to get and then enter the geometry chart and compare how the size compares to what I already own. I've also entered some of my remote friends bikes to see how they match up and how we can exchange components to match fit to see if it's feasible to try out each-others bikes next time we meet.
I've also helped out friends to evaluate which bike to buy, comparing different manufacturers sizes and geometries.

I could see it being used to configure the fit of a new bike to match that of an existing bike. There are other ways to do it of course, but this could be used.

Thank you very much for putting this together and providing it to the world.
