Painting the exterior of your home or property in Singapore is a big decision and a significant investment. Whether you’re painting a new landed house, touching up an HDB flat, or planning a commercial repaint, knowing how much exterior paint you need can save you both time and money. That’s why Painting Services Singapore has created this powerful and accurate Exterior Paint Calculator, a free tool that helps homeowners and contractors calculate paint requirements precisely, without guesswork or overbuying.
This article guides you through using the tool, explains how it works, and highlights why it’s better than most paint calculators available online. With our expertise and experience in Singapore’s painting industry, we’ve built this tool to reflect real-life surface needs, climate considerations, and project complexities.

Use Our Free Exterior Paint Calculator
The Exterior Paint Calculator from Painting Services Singapore is designed to be simple, accurate, and user-friendly. It factors in wall dimensions, number of coats, and paint coverage, while also allowing users to subtract the area of windows and doors, providing a precise estimate of how much paint is needed.
Here’s how to use it:
- Input wall measurements – For each wall, enter width and height. You can add as many walls as needed.
- Account for openings – Input the total square footage of all windows and doors. The calculator subtracts this from the paintable surface.
- Choose a number of coats – Most projects require two coats for durability.
- Set paint coverage – Most paints cover around 350–400 sq ft per gallon. You can adjust this based on your paint brand.
- (Optional) Enter paint price per gallon – Instantly see an estimated cost!
Unlike other basic calculators, ours supports multiple wall entries, window/door area deduction, and Singapore-specific exterior needs. You’ll walk away with a crystal-clear understanding of your paint needs and costs.
Benefits of Using Our Exterior Paint Estimation Tool
There’s no shortage of paint calculators online, but most are generic and not tailored for Singapore’s climate, building types, or renovation trends. The calculator by Painting Services Singapore is specifically designed to address the needs of HDB flats, condominiums, bungalows, and shop houses common in our local setting.
Key benefits include:
- âś… Accurate Results: Based on real wall dimensions and customizable inputs
- âś… Budget Clarity: Includes price estimate to help plan finances
- âś… Time Efficiency: Avoids overspending and reduces leftover paint
- âś… Eco-Friendly: Helps prevent paint wastage
- âś… User-Focused Design: Easy for anyone, no contractor required!
By ensuring that only the actual paintable area is calculated, you’ll never have to worry about buying too much or too little paint again. Plus, this tool is optimized for the humid, tropical conditions in Singapore, where exterior paints face constant exposure to sun, rain, and moisture.
What Makes This Exterior Paint Calculator Better?
Our Exterior Paint Calculator goes beyond surface-level math. It incorporates real-world conditions and knowledge gained from over a decade of professional painting services in Singapore.
Unique advantages of our tool:
- Multi-wall entry support: Easily calculate entire homes, not just single walls.
- Adjustable for coatings: Enter number of coats (1, 2, or more).
- Paint price input: Add your paint brand’s cost per gallon/litre for a full cost estimate.
- Responsive and mobile-friendly: Use it on-site with your smartphone or tablet.
- Tailored for tropical conditions: Paint coverage rates reflect high-humidity application realities.
Many tools use overly simplistic formulas like length × height × 4 walls. But in reality, Singapore’s houses come in all shapes and sizes. That’s why Painting Services Singapore built this tool with flexibility and precision in mind.
Frequently Asked Questions

Most paints cover 350–400 sq ft per gallon, depending on surface texture and paint brand. Rough or porous surfaces absorb more.
Two coats are standard for durability, especially in Singapore’s rain-prone weather. For new walls or drastic colour changes, consider a primer coat too.
This depends on surface area, paint quality, and labour. Use our calculator to estimate paint quantity and multiply by paint cost. Labour typically adds $1.20–$2.50 per sq ft.
