Chalk line to mark the cut

Step 1:

Measure the opening you intend to cover with drywall. Mark the sheet of drywall where you want to cut it.  If the distance is small, you can use a straight-edge, otherwise you will have to mark the sheet on either side and snap a line using the chalk line.

Step 2:

Using the utility knife, cut the drywall along the line.  Note that it is not necessary to try to cut all the way through the sheet.  All you need to do is cut the paper.

Step 3:

Putting one hand on either side of the cut and, with the cut still facing you,  snap the drywall away from you like you are closing a book.  This will snap the white material in the middle of the sheet.

From the backside, cut the paper

Step 4:

If the piece you are cutting is a small piece, it may be necessary to fold the pieces perpendicular to each other and then cut the paper on the other side with a utility knife.  If the pieces are large you can simply snap the pieces the other way and snap the paper on the other side.
