Drywall Texture Calculator

How to measure for drywall texture

1. Measure total area (sq ft or m²) to be textured.
2. Decide how many coats/passes you expect for your chosen texture.
3. Divide (area × coats) by coverage per bag, then round up and add a buffer.

Assumptions to double-check

• Coverage varies by texture type (knockdown, orange peel, skip trowel) and application method.
• Spraying and sanding can increase waste—beginners often need more material.
• Treat this as a planning estimate and confirm with the exact product label.

Buying tips

• Buy enough from the same product line so color/texture matches if you patch later.
• Round up—running short mid-room can make blending difficult.
• If you’re new, plan extra waste for practice and cleanup.
