As a rough guide, basic geometry gives the spot size as

[tex]y = D_H + L \theta[/tex]

where [itex]D_H[/itex] is the diameter of the hole, [itex]L[/itex] is the distance between the hole and the image plane and [itex]\theta[/itex] is the angular diameter of the Sun (in radians). In order to get a "good" image of the Sun, you will need to arrange for [itex]L \theta[/itex] to be larger than [itex]D_H[/itex].

Good luck!
