Accurate Paint Calculator for Your Painting Project

Paint Calculator

How can I calculate how much paint I need?

Are you unsure about how much paint you need for your next project? At Sydney Elite Painters, we’ve created an easy-to-use paint calculator to help you determine the exact amount of paint required. Simply enter the dimensions of the room, including doors and windows, and our calculator will do the rest.
We’re continually enhancing our paint calculator to better serve you. Soon, we’ll introduce a feature that estimates the labor costs for your painting project, giving you a clearer idea of your overall expenses.

For a typical three-bedroom unit or house, you’ll generally need about 20 liters of ceiling paint, with flat sheen being the most common choice. For bathroom ceilings, we recommend using mold-proof or low-sheen paint to combat moisture and prevent mold growth. For walls, approximately 30 liters of low-sheen paint is often required.

When it comes to woodwork, you’ll usually need around 4 to 6 liters. In terms of coverage, one liter of paint typically covers 7 to 10 square meters on previously painted surfaces. For new plasterboard, expect coverage of about 7 square meters per liter, while new render work will require about 5 square meters per liter.

Is the paint estimation accurate?

The paint estimate may not be 100% precise, as porous or rough surfaces can require up to 20% more paint. Likewise, areas with intricate fittings will need additional paint for full coverage. If you’re painting a surface for the first time, plan to use up to 30% more paint to account for wall preparation.

Please note, our interior paint calculator does not factor in ceilings. Be sure to calculate extra paint if you wish to include them in your project.
