Paint Coverage Formula:
From: | To: |
The paint coverage calculation determines how many gallons of paint are needed to cover a given surface area based on the paint's coverage rate. This helps in planning and budgeting for painting projects.
The calculator uses the paint coverage formula:
Where:
Explanation: The calculation divides the total area by the paint's coverage rate to determine how many gallons are needed.
Details: Accurate paint calculation prevents over-purchasing (wasting money) or under-purchasing (causing project delays). It also helps estimate project costs.
Tips: Measure your surface area accurately. Check the paint can for its specific coverage rate (typically 350-400 sq ft/gallon for interior paints).
Q1: What's a typical coverage rate for paint?
A: Most interior paints cover 350-400 sq ft per gallon. Exterior paints may cover less (250-300 sq ft/gallon).
Q2: Should I buy extra paint?
A: It's recommended to buy 10-20% extra for touch-ups, mistakes, and future repairs.
Q3: Does surface texture affect coverage?
A: Yes, rough or porous surfaces may require more paint than smooth surfaces.
Q4: How do I calculate area for a room?
A: For walls: (Length + Width) × 2 × Height. Don't forget to subtract window/door areas.
Q5: Does paint color affect coverage?
A: Dark colors or drastic color changes may require additional coats, effectively reducing coverage.
