The good news is that understanding painting costs doesn’t have to be complicated. Here’s the quick answer: the average cost to paint a 12×12 room ranges from $380 to $950 when hiring professionals, with most homeowners paying around $600.

This guide breaks down every cost factor so you can budget accurately and decide the best approach for your project. What Is the Average Cost to Paint a 12×12 Room? Before diving into numbers, you need to understand what you’re actually paying for. A 12×12 room doesn’t mean 144 square feet of painting space. The calculation works differently. Here’s the math: A 12×12 room has a perimeter of 48 feet (12+12+12+12). With standard 8-foot ceilings, you multiply 48 by 8, giving you 384 square feet of wall surface. This is the number contractors use for estimates. Professional Painting Costs Most painting companies near San Diego and across the country charge between $1.50 and $3.50 per square foot. For a standard 12×12 room with 384 square feet of wall space: Budget range: $380 to $575 (using lower-quality paint and less experienced crews) Mid-range: $600 to $750 (quality paint with experienced painters) Premium service: $800 to $950+ (top-tier paint brands and expert craftsmen) The labor cost to paint a 12×12 room typically represents 65% to 75% of the total bill. That means for a $600 job, roughly $400 to $450 goes to labor, while $150 to $200 covers materials. DIY Painting Costs Painting the room yourself cuts out labor expenses entirely. You’ll spend money on: Paint: $90 to $180 (two gallons for two coats) Primer: $15 to $30 (one gallon) Brushes and rollers: $20 to $40 Painter’s tape: $8 to $15 Drop cloths: $10 to $25 Paint tray and liners: $8 to $15 Total DIY cost: $120 to $300 depending on paint quality If you want to gain more information then visit: How much does it cost to paint a room? How Many Gallons of Paint for a 12×12 Room? This question matters because paint is your biggest material expense. One gallon covers approximately 350 to 400 square feet per coat. For 384 square feet of wall space, you need: First coat: 1 gallon Second coat: 1 gallon Total: 2 gallons for two coats Always buy a bit extra.

Understanding these helps you get accurate estimates. Wall Condition and Repairs Walls with cracks, holes, or water damage need fixing before painting. Drywall repair adds $50 to $150 for minor patches in a single room. Extensive damage requiring skim coating can add $200 to $400. Ceiling Height Standard 8-foot ceilings keep costs predictable. Taller walls change everything: 9-foot ceilings: Add 10% to 15% ($60 to $90 more) 10-foot ceilings: Add 20% to 25% ($120 to $150 more) Vaulted or cathedral ceilings: Add $150 to $300 Higher ceilings require more paint, extra labor time, and sometimes scaffolding. Number of Coats Most rooms need two coats for proper coverage. Adding coats increases both material and labor costs by about 40% per additional coat. Going from dark to light colors often requires three coats, pushing a $600 job to $840. Trim, Doors, and Baseboards Basic estimates typically cover walls only. Including trim and doors adds: Baseboards: $1.50 to $2.50 per linear foot Door frames and doors: $50 to $100 per door Window trim: $25 to $75 per window Crown molding: $2 to $4 per linear foot A 12×12 room with one door, one window, and standard baseboards adds roughly $150 to $250 to your total. Paint Quality and Finish Paint prices vary widely based on brand and finish: Budget brands ($25 to $35/gallon): Acceptable for low-traffic areas but may require more coats. Mid-range brands ($40 to $60/gallon): BEHR, Valspar, and Sherwin-Williams contractor grades offer good durability. Premium brands ($70 to $110/gallon): Benjamin Moore Aura, Farrow and Ball, and high-end Sherwin-Williams provide superior coverage and color depth. Paint finish also matters for both cost and appearance: Flat/matte: Least expensive, hides imperfections, hard to clean Eggshell: Slight sheen, easier to wipe down, good for bedrooms Satin: More durable, works well in high-traffic areas Semi-gloss: Best for trim and moisture-prone areas High-gloss: Most expensive, very durable, shows every wall flaw Room Type and Purpose Bedroom painting typically costs less than kitchens or bathrooms because these rooms need moisture-resistant paint and often have more trim work. A basic 12×12 bedroom runs $400 to $650, while a similar-sized kitchen might cost $550 to $800. Geographic Location Where you live significantly impacts the cost of interior painting. Painter hourly rates vary: Small towns and rural areas: $20 to $30/hour Mid-sized cities: $30 to $40/hour Major metros like San Diego, New York, San Francisco: $40 to $60/hour A painter near San Diego typically charges 25% to 40% more than one in smaller California cities.
