Drywall and Insulation Calculators & Guides
Wall and ceiling sheet counts, joint tape linear feet, bucket yield for joint compound, and fiberglass batt or blown-in insulation requirements.
Calculators
- Drywall Sheet Calculator — Calculate standard 4x8, 4x10, and 4x12 sheetrock gypsum boards for walls and ceilings with door/window deductions.
- Drywall Mud Calculator — Calculate ready-mix all-purpose joint compound 4.5-gal buckets, paper tape rolls, and setting-type hot mud bags.
- Drywall Screw Calculator — Calculate 1-1/4" or 1-5/8" drywall screws (count and 1 lb / 5 lb boxes) based on stud spacing (12" field, 8" perimeter).
- Batt Insulation Calculator — Calculate fiberglass and mineral wool batt insulation bags/rolls (R-13, R-15, R-19, R-21, R-30, R-38) for 16" or 24" OC framing.
- Blown-In Insulation Calculator — Calculate loose-fill cellulose or fiberglass blown insulation bags (R-30, R-38, R-49, R-60) for attic retrofits.
- Spray Foam Calculator — Calculate closed-cell (R-7/in) and open-cell (R-3.8/in) spray foam board feet (bd ft) kits (Froth-Pak 200 / 600).
- Drywall Corner Bead Calculator — Calculate 8-ft and 10-ft metal, vinyl, paper-faced, and bullnose outside corner beads.
- Vapor Barrier Calculator — Calculate 6-mil or 10-mil polyethylene sheeting rolls (10x100 ft = 1,000 sq ft) and seam sealing tape.
