How to Estimate Interior Paint
Estimate wall area, coats and product coverage before purchasing paint.
Measure perimeter and height
Wall area starts with room perimeter multiplied by wall height.
Subtract large openings
Doors and windows can be deducted for a closer first-pass estimate.
Count coats
Color changes and porous surfaces may need more coats or primer.
Use the product label
Coverage varies by paint, surface texture and application method.
Keep touch-up material
A small reserve can help with later repairs and color matching.
