Cost Estimate to Paint a 25x15 Living Room: A Practical Painting Budget & Tips from a Designer's Perspective

Over the years as an interior designer, I’ve helped many homeowners refresh their living rooms, and painting is often the quickest way to make a visible transformation. A 25x15 living room is a moderate-sized space, and estimating the paint cost depends on several factors: wall height, surface condition, type of paint, and whether you’re hiring a professional or going DIY.

How to Calculate the Area

First, multiply the perimeter by the wall height. For example, if your walls are 8 feet tall, the total wall area is (25+15+25+15) x 8 = 640 sq ft. You’ll need to subtract windows and doors for accuracy, but I usually round up slightly to account for touch-ups.

Paint & Material Costs

One gallon of paint typically covers 350–400 sq ft. For 640 sq ft, you’d need about 2 gallons per coat, and most people prefer two coats for an even finish — that’s 4 gallons in total. Quality interior latex paint can cost $30–60 per gallon, so expect $120–240 for paint alone. Add $20–40 for primer if needed, plus $30–60 for supplies like rollers, brushes, and tape.

Labor Costs

If you hire a professional, labor can be $1.50–$3.50 per sq ft of wall area, including prep and cleanup. For this size, that’s roughly $960–$2,240. DIY obviously saves here, but remember the time commitment and need for clean finishing.

Total Estimated Range

DIY: $150–$350

Professional: $1,100–$2,500

The final price will vary with wall condition, ceiling painting inclusion, trims, or special finishes like accent walls or textured coats.

My Tip

If you’re on a budget, invest in higher-quality paint for better coverage and durability — it saves money in the long term by reducing repaint frequency. Also, prep your walls properly; a smooth surface makes any color pop more vibrantly.
