Drywall – Scoring depth for cutting drywall

drywall

new DIY’er here. I started on my first project to finish the walls of my garage(2 side walls). I hope I can pull this off(half way thru so yay).

Okay so here is my question:

I have got a 4×8 drywall that I need to cut to make 2 4×4 pieces and I took a utility knife and made a score, but when I try to snap it, it doesn’t. This is my first time cutting a drywall. So I am not sure if I am not applying enough pressure, or did not score it deep enough or something else. I watched so many youtube videos on this and no where on one talks about the depth of scoring, so I am assuming I am not doing something right(my position, drywall position, enough pressure etc.)

One last thing I can possible try is put the board face down, put one foot on one side and lift up the other side to snap it, can I do that or will I damage the drywall.

It also helps if you can put a straight edge such as a 2x4 under the drywall along the edge you want to break along. Scoring plus the straight else is usually sufficient to get a nice break without too much force.
