How to Cut Drywall on a Wall

Wall-mounted drywall cutting has gotten complicated with all the technique debates, tool options, and clean-cut requirements flying around. As someone who has cut drywall in every situation, I learned everything there is to know about getting precise cuts. Today, I will share it all with you.

Basic Techniques

Probably should have led with this section, honestly—the right technique depends on the cut type:

• Straight Cuts: Score with utility knife, snap along line
• Electrical Boxes: Mark location, cut with keyhole saw
• Circular Holes: Rotary tool or hole saw

Tools Needed

That’s what makes proper tool selection endearing to us drywall installers:

• Utility knife with sharp blade
• T-square or straightedge
• Keyhole saw (jab saw)
• Rotary cutout tool
• Pencil for marking

Scoring and Snapping

1. Mark cut line on face
2. Score deeply along line with utility knife
3. Support sheet and snap away from scored side
4. Cut backing paper with knife

Cutting for Outlets

1. Measure box location from reference points
2. Transfer measurements to drywall
3. Plunge keyhole saw through face
4. Cut along marked lines

Tips for Clean Cuts

• Keep utility knife blade sharp
• Use firm, consistent pressure when scoring
• Make multiple light passes rather than one heavy pass
• Support drywall to prevent breakage
