The hole in the barrier is usually chosen to have the same or smaller diameter (d) than the pinhole lens front lens element.
When the pinhole lens front element is set back from the barrier surface, the lens is, in effect, viewing through a tunnel, and the image has a narrower FOV than the lens can produce.

For a pinhole lens, the larger the entrance lens diameter, the more light gets through to the camera sensor, resulting in better picture quality, all other conditions remaining the same.
