Paint Calculator Tool

A paint calculator helps you determine exactly how much paint you need for your painting project. By calculating the surface area and accounting for doors, windows, and multiple coats, this tool prevents overbuying or running short of paint. It’s essential for budgeting, planning trips to the store, and ensuring professional-looking results.

How to Use the Paint Calculator

Step 1: Select Project Type. Choose between "Single Wall" (for painting one wall) or "Entire Room" (for painting all four walls).

Step 2: Choose Your Uni.t Select your preferred measurement unit: Feet or Meters.

Step 3: Enter Dimensions

• Single Wall: Enter wall length and height
• Entire Room: Enter room length, width, and ceiling height

Step 4: Add Doors and Windows. Input the number of doors and windows. The calculator automatically subtracts their area (standard door: 20 sq ft, window: 15 sq ft) from the total.

Step 5: Select Number of Coats. Choose 1, 2, or 3 coats. Two coats are recommended for most projects.

Step 6: Set Paint Coverage Enter your paint's coverage rate (default: 350 sq ft per gallon). Check your paint can for the exact coverage rate, as it varies by brand and finish.

Step 7: Calculate. Click "Calculate" to see your results, including total area, exact gallons needed, rounded-up gallons, and quarts as an alternative.
