How much would a painter charge to paint a 12x12 room?

Expect $617 to $1,262 at national rates with standard prep, walls only. In a lower cost of living area with clean walls it drops to $508 to $1,002, and in a major metro with heavy prep it runs $1,120 to $2,472. That covers labor at $1.25 to $3.00 per sq ft across 369 sq ft of wall, plus materials at a 15% contractor markup. Adding the ceiling, trim, or doors is extra.

How much does it cost to paint a 12x12 room yourself?

About $135 in paint. A 12x12 room with 9 ft ceilings has 369 sq ft of paintable wall, which needs 2.4 gallons for two coats with a waste buffer, so you buy 3 gallons of eggshell at roughly $45 each. Budget another $40 to $60 for a roller, tray, brushes, tape, and drop cloths if you do not already own them.

Is it worth hiring a painter for one 12x12 room?

For a straightforward repaint with clean walls, no. The labor is a day of rolling and the savings are several hundred dollars. Hiring makes sense when the walls need real repair, when you are covering wallpaper or a dark color, when the ceilings are above 9 ft, or when you want cut lines sharp enough to survive close inspection.

Budget

The two numbers, side by side

A 12x12 room is 369 sq ft of paintable wall after one door and two windows come out. Doing it yourself, you buy 3 gallons of eggshell at about $45 each and spend $135. Hiring a painter at national rates with standard prep costs $617 to $1,262, because labor is priced at $1.25 to $3.00 per sq ft of wall and materials carry a 15% markup on top.

✓ Do it yourself: $135, plus a roller, tray, tape, and about a day of work.
✓ Hire a painter, national average, standard prep: $617 to $1,262.
✓ Hire a painter, lower cost of living, light prep: $508 to $1,002.
✓ Hire a painter, major metro, heavy prep: $1,120 to $2,472.

Overview

Ceiling height moves the number more than you think

Room dimensions get all the attention, but the wall area is the perimeter times the ceiling height, so an extra foot of height adds surface to all four walls at once. Going from 8 ft to 10 ft ceilings in the same 12x12 room adds nearly 100 sq ft of wall.

✓ 8 ft ceilings: 321 sq ft of wall to paint, 2.1 gallons for two coats (buy 3), $135 in paint, or $557 to $1,118 to hire it out.
✓ 9 ft ceilings: 369 sq ft of wall to paint, 2.4 gallons for two coats (buy 3), $135 in paint, or $617 to $1,262 to hire it out.
✓ 10 ft ceilings: 417 sq ft of wall to paint, 2.7 gallons for two coats (buy 3), $135 in paint, or $677 to $1,406 to hire it out.

Specs

How these numbers are worked out

A 12x12 room with 9 ft ceilings has 432 sq ft of gross wall. Subtracting one door and two windows at 21 sq ft each leaves 369 sq ft of paintable wall. Two coats plus a 10% waste buffer against 350 sq ft per gallon of eggshell puts it at 2.4 gallons, so you buy 3. Labor runs $1.25 to $3.00 per sq ft of surface at national rates with standard prep, and painters mark materials up about 15%.

✓ Ceilings, trim, doors, and baseboards are not included. Each one adds surface and cost.
✓ Prep is the biggest swing in a quote. Wallpaper removal or a dark-to-light change adds about 35%.
✓ Region matters more than most people expect: a major metro runs about 55% above the national rate.

Common mistakes

What inflates a quote you did not expect

The room size sets the floor. These are what move a quote above it.

✓ Dark to light. Covering a saturated color can take three coats instead of two, which adds paint and about 20% to labor.
✓ Wallpaper. Removal is charged as heavy prep and can add a third to the whole job.
✓ Ceilings and trim. Adding the ceiling to a 12x12 room is another 144 sq ft, and trim, doors, and baseboards are quoted separately.
✓ Furniture left in the room. Some painters charge to move and mask it, others will not start until it is out.
