Tips for Measuring and Cutting Drywall: Straight Cut Lines

Use the Straight Cut Lines!

Dina Montgomery
When it comes to measuring and cutting drywall, there is no hidden secret. There are a few tricks, tips, and some specialty tools to help you streamline your ability and to improve your accuracy in cutting drywall panels. Marking straight cut lines on drywall does require you to have a sharp eye and the right type of tools. One of those tools would be a T-Square tool. A straight cut line mostly refers to a line that is square to an edge or square to the end of the drywall panel. Most of the methods for squaring lines on drywall will mostly rely on the edge as a reference or guide. This method would call for a T-Square tool.

Marking straight cut lines with a T-Square tool

The tools and material you will need:

4-foot T-Square tool

Folding ruler or measuring tape

Drywall panels

Pencil

Utility knife

Measuring the cut lines

Take your measuring tape or folding ruler and measure to determine the size of the piece you need. Then you will transfer and mark the dimensions on the drywall panel.

Marking the lines on the drywall panel

Take the 4-foot T-Square tool and place it against the drywall panel so that the long end of the blade is parallel with the cut line that you intend to mark. Next you need to slide the T-Square tool along the edge of the panel until the edge of the blade lines up with the mark you just made. Take your pencil and mark it along the blade, marking the cut line. If the perpendicular cut line is needed, you will just repeat the process. Take a utility knife, and wearing your eye protection, slice the good side of the drywall panel with a cutting depth of 1/8th of an inch.

Snap the cut line

Now working in front of or behind the drywall panel, with a quick motion, snap the drywall panel along the cut line, and carefully fold it back. Making sure not to tear the cut drywall panel; just allow the drywall panel to break along the cut line. The drywall panel should only be held together by the paper backing.

Slice the back and separate the drywall panel

Take the utility knife and slice the back side of the drywall panel to cut through the paper, and then you can separate the two pieces of drywall.

These instructions should help you with your techniques in making precise and dustless cuts in drywall panels.
