How to render my model the exact same size, on different canvas sizes?

Hi all!

I currently have a situation where my object renders a different size on 2 different browsers.
The issue was: my bookmark bar. When I dissabled this, my browser screens were almost identical in size. That’s why it came to me: the model is rendering in different sizes depending on the size of the canvas.

how can I make sure that, no matter what the size of the canvas is (or the container where the canvas is residing in), the model is always the exact same size?

It depends - vertical size of the canvas is the part that’s scaling when you resize the browser / the canvas element. Horizontal aspect adjusts to take into account vertical size of the canvas and FOV of the camera.

The easiest way would be to just have a constant size of the canvas (or at least a constant aspect ratio of it.)
