Paint Quantity Calculator for Wall Finishes

Prepared By: Parag Kamlakar Pal – Owner of www.civilnotess.com

Calculating the right amount of paint for your wall finishes can be crucial for efficient budgeting and project planning. Here’s a practical calculator to help you determine the amount of paint needed based on wall dimensions and paint coverage.

Example Calculation

Let’s assume the following example for a practical calculation:

• Wall height: 10 feet
• Wall width: 15 feet
• Number of walls: 4
• Coverage of Grade A paint: 350 square feet per gallon
• Coverage of Grade B paint: 250 square feet per gallon

Using these values, the total wall area is:

Total Wall Area = 10 feet × 15 feet × 4 walls = 600 square feet

The paint required for each grade is calculated as follows:

• Paint required for Grade A = 600 square feet / 350 square feet per gallon ≈ 1.71 gallons
• Paint required for Grade B = 600 square feet / 250 square feet per gallon = 2.4 gallons

Calculate

function calculatePaint() {
// Get values from form
let height = parseFloat(document.getElementById(‘height’).value);
let width = parseFloat(document.getElementById(‘width’).value);
let walls = parseFloat(document.getElementById(‘walls’).value);
let coverageA = parseFloat(document.getElementById(‘coverageA’).value);
let coverageB = parseFloat(document.getElementById(‘coverageB’).value);

// Calculate total wall area
let totalWallArea = height * width * walls;

// Calculate paint required for each grade
let paintRequiredA = totalWallArea / coverageA;
let paintRequiredB = totalWallArea / coverageB;

// Display results
document.getElementById(‘resultA’).textContent = `Paint required for Grade A: ${paintRequiredA.toFixed(2)} gallons`;
document.getElementById(‘resultB’).textContent = `Paint required for Grade B: ${paintRequiredB.toFixed(2)} gallons`;
}
