What is the best camera lens to choose for my bed size?

To answer this question requires one additional piece of information: The height above the bed that you plan to mount the camera.

LightBurn now has a helper that will do the ugly math for you. Go to Help > Camera Selection Help and the software will use the current workspace size by default, and show you the minimum mounting heights for all the cameras we sell:

This number is the absolute minimum required for the camera to see the whole working area. You will need to allow a little extra because the un-warping that happens in the software will trim a small percentage of the image away as well. We recommend allowing an extra inch or two (25 to 50mm).

In general, it is best to use a narrower lens (smaller angle) if you can, because there is less distortion to correct, and therefore the accuracy will be better.
