Is there a minimum requirement for a character to have line of effect with Shadow Jaunt/Stride/Blink?

I’m pretty sure this has been asked already but I can’t find the question in question, so I hope I don’t break any rules by asking again.

The Shadow X maneuvers from Shadow Hand have a line of effect and line of sight requirement to work. Let’s say I want to teleport through a hole in a wall. According to both line rules, as long as I can see though the hole and there is nothing obstructing the path though the hole, I should be able to teleport though it.

Is there a minimum size the hole has to be for my character to be able to traverse the hole?
