Living room painting cost is driven by wall area and ceiling height, how much wall preparation strong window light demands, where the color stops in an open floor plan, and trim, built-ins and furniture. A 16 by 20 foot room with 9 foot ceilings takes about 3 gallons for two coats.
A 16 by 20 foot living room with 9 foot ceilings has about 648 square feet of wall before openings. At the 400 to 450 square feet per gallon Benjamin Moore lists for Regal Select, two coats are about 3 gallons. Vaulted or two-story ceilings add wall area quickly and require taller ladders or planks.
Large windows throw light across walls, showing every seam and patch. The Gypsum Association's GA-214 recommends Level 5, a skim coat over the entire wall, where severe lighting occurs, and says paints with sheen above flat are not recommended over Level 4. Choosing eggshell on a long, side-lit wall can mean skim coating first.
In open plans, living rooms flow into dining rooms, halls and kitchens with no door to stop the color. The color has to end at a logical inside corner or trim line, which can expand the job into adjacent spaces. Deciding the break points early keeps the scope clear.
Yes. Built-in shelving and mantels are painted with enamel like trim; Benjamin Moore Advance needs 16 hours between coats. Fireplace brick is masonry and needs a masonry-compatible primer, with the firebox left unpainted.
Living rooms hold the most furniture to move and cover. In pre-1978 homes, paid work disturbing more than 6 square feet of painted surface per room falls under the EPA lead rule, with containment and cleaning verification.
Where the color stops, which walls and ceilings are included, how much wall preparation is planned, and which trim and built-ins are painted. Pennsylvania's Home Improvement Consumer Protection Act requires the contract to include a description of the work, the materials to be used and specifications that cannot change without a written change order.

A 16 by 20 foot living room with 9 foot ceilings has about 648 square feet of wall. At 400 to 450 square feet per gallon for Benjamin Moore Regal Select, two coats come to about 3 gallons, minus doors and windows. Vaulted ceilings and stairwells add area.
Living rooms are larger, often have taller ceilings, more windows and side light that demands smoother walls, built-ins or fireplaces, open connections to other rooms, and more furniture to move. Each adds labor beyond the extra paint, and wall preparation under strong window light is often the largest of them.
In open plans it often makes sense, because the color has to stop at a natural break such as an inside corner or trim line. Painting connected spaces together avoids a visible line where old and new paint meet and lets one batch of paint cover both, keeping the color consistent.
Often one to two days, depending on wall prep, ceiling height, trim and built-ins. Premium wall paints such as Regal Select recoat in 1 to 2 hours, but skim coating, tall walls and enamel trim with 16 hour recoats extend the schedule.
