1. What is the Paint Calculator?

The Paint Calculator estimates how many gallons of paint you need to cover a given area based on the coverage rate of the paint. It helps prevent buying too much or too little paint for your project.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Area — Total surface area to be painted in square feet
• Coverage Rate — How many square feet one gallon of paint will cover (typically 350-400 sq ft/gallon)

Explanation: The calculation divides the total area by how much area one gallon can cover to determine total gallons needed.

3. Importance of Accurate Paint Calculation

Details: Proper 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 (length × height) and subtract window/door areas
• Check the paint can for the specific coverage rate (varies by paint type)
• Round up to the nearest whole gallon
• Add 10% extra for touch-ups and mistakes

5. Frequently Asked Questions (FAQ)

Q1: What's a typical coverage rate?
A: Most paints cover 350-400 sq ft per gallon, but check your specific paint as premium paints may cover more.

Q2: Should I account for multiple coats?
A: Yes, multiply your final gallons by the number of coats needed (usually 2 for good coverage).

Q3: How do I calculate wall area?
A: Measure length × height for each wall, then subtract areas not being painted (windows, doors).

Q4: Does texture affect coverage?
A: Yes, textured surfaces may require 10-20% more paint than smooth surfaces.

Q5: What about ceilings and trim?
A: Calculate these separately as they often use different paints with different coverage rates.
