Plan Your Project with Our Interior Paint Calculator
An accurate estimate of paint quantity is essential to avoid both underbuying and overbuying. Our interior paint calculator at Painting Services Singapore is specifically designed for local homes, taking into account Singapore’s common residential layouts and room sizes. From small studio apartments to spacious landed homes, the calculator is engineered to be adaptable for all interior painting needs.
Paint coverage varies based on several factors such as surface texture, number of coats, and paint quality. On average, most wall paints cover around 10 square meters per liter per coat. However, this figure changes with textured walls, dark color base coats, and older surfaces. Our tool accounts for these variables, ensuring a personalized and more accurate estimation.
With our tool, you’re empowered to plan more efficiently, reduce wastage, and stay within your renovation budget. It’s also mobile-friendly, so you can calculate while you’re on the go, whether you’re at the paint store or on-site with your contractor.
Why Use Our Paint Calculator?
Save Time & Money
Knowing how much paint to buy before starting your project saves both time and money. There’s no need to pause your work for a last-minute store run or waste money on unnecessary gallons. The Painting Services Singapore calculator minimizes both scenarios by giving you an accurate prediction.
Tailored for Singapore Homes
Our tool is developed with the specific dimensions and styles of Singapore’s residential properties in mind. Whether you’re painting a 3-room HDB flat, a BTO unit, or a condo apartment, this tool adapts to your needs effortlessly.
Full Control & Flexibility
You can input total wall measurements, include ceiling area, and even subtract windows and doors. Plus, you can adjust for one or two coats depending on your paint preference.
Compatible with Any Brand
Unlike some paint calculators that only work for specific brands, ours works for any paint including popular choices like Nippon Paint, Dulux, Jotun, and more. Simply check your chosen paint’s coverage information and input it into the tool.
How to Use the Calculator
Using our wall paint coverage calculator is straightforward, even if you have no experience in painting. Here’s a step-by-step guide:
- Measure Wall Height and Width: Use a tape measure to calculate the total wall area. If painting multiple walls, sum up their widths.
- Input Door and Window Count: Standard doors (1.9m x 0.8m) and windows (1.5m x 1.2m) are deducted from total surface area to avoid overestimation.
- Choose Number of Coats: Two coats are recommended for new paint jobs or color changes.
- Include Ceiling (Optional): Tick this box if you also plan to paint your ceiling. The tool will calculate this using your wall width as an estimate.
- Enter Paint Coverage: Refer to the paint can or product page. Most standard interior paints offer coverage between 8-12 square meters per liter per coat.
- Click ‘Calculate’: Instantly receive an accurate estimate of how many liters of paint are required.
By following these steps, you’ll get a precise estimate in seconds, far more accurate than manual guesswork.
Advanced Features
Our paint calculator goes beyond the basics. Here are some features that make it stand out from other tools like those from Tikkurila or basic spreadsheets:
- Multiple Surface Inclusion: Calculates total area for walls and ceilings.
- Dynamic Coverage Input: Adjusts for different paint types and brands.
- Smart Area Deduction: Automatically deducts standard-sized doors and windows.

- Bedrooms: Average 10–12 square meters per wall.
- Living Rooms: Wider coverage with more windows; the calculator adjusts accordingly.
