Drywall Calculator: Sheet Plan

Stop dividing square feet by 32. Drywall Calculator draws every wall, places every sheet and picks 8 to 16 ft lengths for the fewest seams, the way pro hangers plan a job.

HOW IT WORKS
1. Enter the room: length, width, wall height, and whether the ceiling gets board too.
2. Add doors and windows where they really are.
3. See every wall and the ceiling drawn to scale, sheet by sheet, then open your order list.

A SHEET LAYOUT, NOT JUST A NUMBER
• Every sheet placed on the wall and coloured by length: 8, 9, 10, 12, 14 and 16 ft, plus 54 in sheets for 9 ft walls
• Fewer seams to tape: long sheets hung across the studs, or upright on narrow walls
• Butt joints land on studs, are staggered between rows and kept away from the middle of the wall
• Joints kept 12 in clear of door and window corners
• Best finish or Least material: switch and see what changes
• See how much less taping you get than with only 8 ft sheets

YOUR DRYWALL TAKEOFF
• Sheets grouped by size, the way the lumberyard sells them
• Screws counted from Gypsum Association spacing, sheet by sheet
• Joint tape from the real length of your seams and inside corners
• Joint compound and outside corner bead
