My name is Thomas and I am a programmer, motion designer, and photographer. I made this tool, because I often make carousels and multi-image posts on Instagram, where I need to know the aspect ratio of the canvas I'm working on. That's what I use it for, but you're welcome to use it for whatever you want. I'm currently driving somewhere between Denmark and Japan with my girlfriend in a Toyota Land Cruiser. Check out more of my work and tools here.
