1. What is the Paint Calculator?

The Paint Calculator By Square Foot estimates the amount of paint needed to cover a given area based on the paint's coverage rate. It helps in planning painting projects and purchasing the right amount of paint.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Square Feet — Total area to be painted
• Coverage — Paint coverage rate (typically 250-400 sq ft per gallon)

Explanation: The calculation divides the total area by the paint's coverage rate to determine how many gallons are needed.

3. Importance of Accurate Paint Calculation

Details: Accurate paint calculation prevents over-purchasing (wasting money) or under-purchasing (inconvenience of additional trips). It also helps estimate project costs and time.

4. Using the Calculator

Tips:

• Measure the total square footage of all surfaces to be painted
• Check the paint can for coverage rate (default is 350 sq ft/gallon)
• Add 10-20% extra for mistakes, touch-ups, and uneven surfaces

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate square footage?
A: For walls: (Height × Width) for each wall, then sum them. Subtract window/door areas.

Q2: What's the average coverage rate?
A: Typically 250-400 sq ft per gallon, depending on paint type, surface texture, and application method.

Q3: Should I buy extra paint?
A: Yes, it's recommended to buy 10-20% more than calculated for touch-ups and future use.

Q4: Does this account for multiple coats?
A: No, multiply the result by the number of coats you plan to apply (typically 2 coats).

Q5: How does surface texture affect coverage?
A: Rough surfaces may require 20-30% more paint than smooth surfaces.
