That depends massively on how the camera is oriented, but have a look at this:

If you take a surveillance camera as an example, then e.g. the height of a person is quite difficult to estimate, but if you have a camera perpendicular to the surface the items you wish to measure are on, then the math gets a lot easier to handle.
