  • Paint, two coats: $135.
  • Hire a painter, national average: $707 to $1,478.

Overview

The four-gallon line

A 12x16 room stays inside three gallons until the ceilings hit 10 ft, at which point it needs a fourth. Living rooms are also the most likely room in a house to have raised ceilings, so measure rather than assume.

  • 8 ft ceilings: 385 sq ft of wall to paint, 2.5 gallons for two coats (buy 3), $135 in paint, or $637 to $1,310 to hire it out.
  • 9 ft ceilings: 441 sq ft of wall to paint, 2.8 gallons for two coats (buy 3), $135 in paint, or $707 to $1,478 to hire it out.
  • 10 ft ceilings: 497 sq ft of wall to paint, 3.2 gallons for two coats (buy 4), $180 in paint, or $828 to $1,698 to hire it out.

How these numbers are worked out

A 12x16 room with 9 ft ceilings has 504 sq ft of gross wall. Subtracting one door and two windows at 21 sq ft each leaves 441 sq ft of paintable wall. Two coats plus a 10% waste buffer against 350 sq ft per gallon of eggshell puts it at 2.8 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.

What makes a living room harder than a bedroom

Same math, more obstacles. Budget time rather than money for these.

  • More and bigger windows, which means more cutting in and more masking, though it does reduce paintable area.
  • Furniture that does not leave the room easily. Move it to the center and cover it rather than fighting it to the door.
  • Feature walls and open-plan edges, where the paint has to stop at a corner with no trim to hide the transition.
  • Ceilings above 9 ft, which put you on a ladder for the cut-in and roughly double how long the edges take.
