How to use this estimate
Match the patch to the damage
Measure a roughly rectangular opening. The suggested method is a starting point; damage beyond the visible hole may change the repair.
Measure each hole
Use the widest and tallest part of the opening. Group holes of the same size.
Plan the materials
Small holes may need only compound. Larger patches need drywall and sometimes backing and tape.
Confirm before buying
Match the board thickness and wall assembly. Prime after the patch dries.
The math
From opening to patch size
Example: one 4 × 5 in opening
- A paper-face patch can be cut about 1 in larger on every side: 6 × 7 in.
- Board area: 6 × 7 ÷ 144 = about 0.29 sq ft.
- The paper flap replaces separate tape for this repair approach.
The tool estimates a patch, not a structural or fire-rating repair specification.
