Expert Guide: Planning Your Room Renovation
Whether you're refreshing your drawing room in Lahore or repainting a bedroom in Mumbai, getting the paint quantity right is the first step to a successful DIY project. Our free room paint calculator helps you estimate exactly how many gallons or liters of paint you need, saving you from unnecessary trips to the hardware store.
Choosing the Right Paint for South Asian Climates
South Asia's heat and humidity mean your walls need high-quality protection. Popular brands like ICI Dulux, Brighto, and Master Paints in Pakistan, or Asian Paints and Berger in India, offer specialized emulsions for exterior and interior walls. Our tool calculates coverage based on standard yields (approx. 350-400 sq ft per gallon).
Deducting Apertures
Our calculator automatically deducts the area of doors and windows from your total wall surface area. This ensures you don't overbuy paint for areas that won't be covered.
Layering Strategy
Most professional painters in South Asia recommend at least two coats for a uniform finish. If you're switching from a dark color to a light one, consider three coats or a primary base primer.
Frequently Asked Questions
How much paint do I need for a 12x12 room?
A standard 12x12 room with a 9-foot ceiling has roughly 432 sq ft of wall area. With two coats and deductions for one door and one window, you'll typically need about 2.5 to 3 gallons of paint.
Is one gallon of paint enough for a small room?
One gallon usually covers up to 400 sq ft for a single coat. For a small bathroom or accent wall, one gallon is often plenty, but always calculate for two coats for the best finish.
What is the difference between liters and gallons?
One US gallon is approximately 3.78 liters. In Pakistan and India, paint is often sold in 1-liter, 4-liter (gallon), and 16-liter (bucket) sizes. Our tool provides results in both for your convenience.
Should I include the ceiling in my calculation?
This tool focuses on wall area. If you're painting the ceiling, calculate its area separately (Length × Width) and add it to your total paint requirement.
