Shopping List
Joint compound / spackle0.5 qt
Lightweight spackle is usually enough for tiny holes.
Sandpaper / sanding sponge2 pcs
Use fine grit on the final pass before primer.
Primer0.5 qt
Helps stop flashing around the patch.

Prep Checklist
- • Cut away loose paper, crumbling gypsum, and paint edges before filling.
- • Use a dust mask and drop cloth if you need to sand or cut the wall open.
- • Prime the repaired area first so the finish coat blends more evenly.
How to Use This Calculator
- Pick the damage type — Choose hole, crack, water damage, or corner repair so the calculator can suggest the right fix.
- Set the patch size — Use a preset or enter your own size. Measure the damaged area, not the whole wall.
- Adjust the wall texture — Smooth blends fast, while orange peel and popcorn take extra finish work.
- Toggle paint and labor — Need paint or labor in the estimate? Turn them on.
- Review the repair plan — Skim the method, shopping list, timeline, and DIY fit before you buy materials.
How We Calculate
Repair Area = Width × Height × Quantity
Compound Estimate = Repair Area × Method Factor × Texture Factor
Labor = Active Work Hours × Hourly Rate
Method Assumptions
- • Tiny holes: spackle only
- • Medium holes: mesh patch + compound
- • Large holes: cut-in drywall patch
- • Cracks: tape + compound
- • Water damage: replace damaged section
Texture Assumptions
- • Smooth: 1.0× finish effort
- • Light orange peel: 1.1×
- • Heavy texture: 1.2×
- • Popcorn: 1.3× and usually harder to blend (yep)
Example Calculation
- Repair: medium hole, 8" × 8", quantity 1
- Repair area: 8 × 8 ÷ 144 = 0.44 sq ft
- Recommended method: mesh patch + compound
- Texture: smooth wall = 1.0× finish factor
- Compound: 0.44 sq ft × method factor = about 0.5 qt
Method assumptions come from common Gypsum Association / USG patching practices. Labor and cost ranges are rough guides only, based on Homewyse 2026 wall repair references.
