Help with perspective

I am trying to figure out a way to view my mesh as I would view it if it were a solid object in real life. That is, I want the perspective in blender to match real life perspective, and I have no idea how to do this. I know I can mess around with the lens value, but really that is just guess work and I would like get it exact or as close as possible to real perspective. I have heard that setting the lense value to 55-60 mimics the human eye, but that doesn’t work. The perspective still looks warped. I would think having a feature that matches the perspective to real life perspective would be standard as having a mesh that looks the way it would in real life seems like a pretty basic necessity.

you can find some object of simple geometry, like door and corner of the room, and take all the measurements. Then build a simple scene and scale and position objects accordingly. (don’t forget to set units to metric or imperial) then you can use good old pencil measurement method to get the proportions just right

Two things to remember:

  1. Blender’s default scale is 1m / BU (so the default cube is actually pretty huge). Keep this in mind when checking scales.
  2. If you set Blender’s camera to the same focal length as your eye, then the camera would see everything your eye would see… except that the onscreen camera view is only a small sector of what you can see. An easy way to see what I’m talking about is to set it to that seemingly warped focal length, and then lean forward until your nose (almost) touches the screen. The “distortion” will largely “correct itself”, since the screen-eye image is now mapped in a more realistic manner.
