Paint Coverage Reference
| Surface Type | Coverage | Notes |

| Textured walls | 250-300 sq ft/gal | Knockdown, orange peel textures |
| Rough/Stucco | 200-250 sq ft/gal | Heavy texture absorbs more paint |

💡 Note
This calculator provides estimates based on typical conditions. Actual paint needs may vary based on paint brand, application method, surface condition, and color change requirements. Buy slightly more paint than estimated to ensure you have enough for touch-ups and complete coverage. Keep your paint receipt for easy returns of unused gallons.
