1. What is the Paint Calculator?

The Paint Calculator estimates the amount of paint needed to cover a given area based on the paint's coverage rate. It helps prevent over- or under-purchasing paint for your project.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Paint (gal) = \frac{Area (ft²)}{Coverage (ft²/gal)} \]

Where:

Explanation: The formula divides the total area by the coverage rate to determine how many gallons of paint are needed.

3. Importance of Paint Calculation

Details: Accurate paint estimation saves money by preventing over-purchasing and ensures you have enough paint to complete your project without multiple trips to the store.

4. Using the Calculator

Tips: Measure your walls carefully, subtract areas not being painted (windows, doors). Standard paint coverage is about 350 ft² per gallon, but check your paint can for exact coverage.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate wall area?
A: Measure length and height of each wall, multiply to get area, then add all wall areas together.

Q2: Does the calculator account for multiple coats?
A: No, multiply the result by the number of coats you plan to apply.

Q3: What's the average coverage per gallon?
A: Most paints cover 250-400 ft² per gallon. Flat paints cover more than glossy paints.

Q4: Should I buy extra paint?
A: It's wise to buy 10-20% extra for touch-ups and coverage inconsistencies.

Q5: How does surface texture affect coverage?
A: Rough textures may require 20-50% more paint than smooth surfaces.
