The quick answer#
A painter's labor runs $1 to $3 per square foot of wall area to paint a room in 2026. For a typical 12 by 14 foot bedroom with 8 foot ceilings, that is $363 to $1,089 for the walls. Doing it yourself, HomeGuide puts paint and supplies for a typical room at $150 to $300.

A 12 by 14 room has 168 square feet of floor and 363 square feet of wall once you take out one door and two windows. A quote of "$2 a square foot" means something very different depending on which of those two the painter has in mind, and a good estimator will tell you which unprompted. Work out your own wall area first with the paint calculator, which subtracts doors and windows the way an estimator does, and you can hold any quote against a number you trust.

Cost by room size#
Wall area grows with the perimeter, not the floor area, which is why a big room is cheaper per square foot of floor than a small one. Doubling a room's floor area does not double its walls. Every figure below assumes 8 foot ceilings, one door, and two windows, and two coats of paint.
| Room size | Wall area | Gallons, 2 coats | Painter labor | DIY paint |
|---|---|---|---|---|
| 10 x 10 | 267 sq ft | 2 | $267–$801 | $30–$100 |
| 12 x 12 | 331 sq ft | 2 | $331–$993 | $30–$100 |
| 12 x 14 | 363 sq ft | 3 | $363–$1,089 | $45–$150 |
| 14 x 16 | 427 sq ft | 3 | $427–$1,281 | $45–$150 |
| 16 x 20 | 523 sq ft | 3 | $523–$1,569 | $45–$150 |
Wall area is 2 x (length + width) x 8 feet, less 21 square feet for a door and 16 for each of two windows, which is how the paint calculator does it. Labor is the wall area at $1 to $3 per square foot, and DIY paint is the gallons at $15 to $50. HomeGuide puts one room with the ceiling and the trim at $600 to $2,000.
Why the ceiling costs so much for its size
A 12 by 14 ceiling is 168 square feet against 363 on the walls, so under half the area, and HomeGuide prices painting one at $1 to $2 per square foot, $168 to $336 here. Painting overhead is slow: it needs a pole or a ladder, cutting in around the perimeter takes as long as a wall does, and the drop cloths have to cover everything rather than a strip along the baseboard.
DIY paint prices#
HomeGuide puts paint and supplies for a typical 12 by 12 room with 8 foot ceilings at $150 to $300. The paint is the part that grows with the room: the 12 by 14 takes 3 gallons, and the rollers, tape, and drop cloths are the same either way.
| Item | Cost |
|---|---|
| Wall paint, per gallon | $15–$50 |
| Primer, per gallon | $15–$30 |
| Wall paint for the 12 by 14 room, 3 gallons | $45–$150 |
| Paint and supplies, typical 12 by 12 room | $150–$300 |
Paint and primer prices are HomeGuide's per-gallon ranges. The $150 to $300 is HomeGuide's figure for a 12 by 12 room; no published figure itemises the supplies, so this page does not.
Labor is most of what a painter charges, so on a 12 by 12 room, at $1 to $3 per square foot of wall, doing it yourself keeps $331 to $993 for $150 to $300 of paint and supplies and a weekend of work. Painting is also the job where a bad result is most visible. The saving improves across several rooms, because the supplies carry over and only the paint has to be bought again.
What moves the price#
Two rooms of the same size can be a hundred dollars apart or double each other. These are the things that decide which.
Ceiling height#
This is pure arithmetic and it is the biggest single swing. Going from 8 foot to 9 foot ceilings adds 12.5 percent to the wall area, and a 10 foot ceiling adds 25 percent. On the 12 by 14 room that is 363 square feet at 8 feet, 415 at 9 feet, and 467 at 10 feet, a little more than the percentages suggest, because the doors and windows do not grow with the ceiling. It also pushes the job onto a ladder or a pole, which slows the cutting in.
Trim, doors, and windows#
Cutting in is the slow part of painting, and every piece of trim adds another edge to cut. A plain room with one door and two windows is quick. The same room with a six-panel door, crown moulding, a chair rail, and a bay window can take twice as long even though the wall area barely changed. Trim and doors are usually quoted separately for exactly this reason.
Number of coats and the color change#
Two coats is standard. Going dark to light is the one that catches people: covering a deep red or navy with an off-white takes a tinted primer and two finish coats, and sometimes three, which adds a coat and a day. Light to dark is easier but still wants the primer tinted toward the finish color. If the walls are staying in the same family, one coat over a sound existing finish is sometimes enough.
Wall repair#
Nail holes and small dings are inside any normal quote. Cracked corners, failed tape joints, water stains, or a wall that needs skim coating are not, and are quoted on top. If you are patching more than a few spots, or hanging new board in the room at all, the drywall calculator will tell you the sheets, mud, and screws you need before the painting even starts. New drywall also always needs a primer coat, because bare paper and joint compound drink paint at different rates and the difference shows through a single finish coat.
Patching or hanging board first
Sheets, mud, and screws for the repair
Enter the room dimensions to get drywall sheets, joint compound, and screw counts before you open a can of paint.
Paint price and coverage#
Paint runs $15 to $50 a gallon and primer $15 to $30, and HomeGuide gives one coverage figure for all of it: a gallon covers 300 to 400 square feet with one coat. The paint calculator defaults to 350, inside that range, and the figure on the can is the one to trust for the paint you actually buy.
The one-coat claim
Premium paints that promise one-coat coverage mean one coat over a similar color on a sealed wall. Over bare drywall, over a patch, or over any real color change, they still need two. Buying a premium gallon does not remove the primer coat, and pricing a job on the assumption that it does is how a weekend project turns into a three-day one.
Checking a quote in two minutes#
Work out the wall area yourself, multiply it by $1 and $3 for the labor, and see where the quote falls. For the 12 by 14 room that is $363 to $1,089 before paint, and HomeGuide puts a 12 by 12 room at $380 to $1,400 for the walls alone, so a $700 quote is squarely normal and one well past $1,400 needs an explanation. Usually there is a good one: the ceiling is in, the trim is in, or the walls need work.
Ask three questions and most of the spread explains itself. How many coats. Is primer included and is it tinted. Are the ceiling and the trim in the price or extra. A painter who answers those without hesitating is quoting the same job as the next painter, and only then are two numbers actually comparable.
The low quote deserves the same scrutiny. A price below the DIY materials cost means somebody is skipping a coat, skipping the primer, or using builder grade paint on a wall that needs better. Anything far under $380, HomeGuide's low end for the walls of a 12 by 12 room, is not a bargain, it is a different job.

Common questions#
How much does it cost to paint a 12 by 14 room?#
Labor for the walls of a 12 by 14 room with 8 foot ceilings is $363 to $1,089, based on 363 square feet of wall area at $1 to $3 per square foot. HomeGuide puts one room with the ceiling and trim at $600 to $2,000. Doing it yourself costs $150 to $300 in paint and supplies for a typical 12 by 12 room, and 3 gallons of wall paint for the 12 by 14 is $45 to $150.
Is it cheaper to paint a room yourself?#
Yes. Labor is most of a painting quote, and on a 12 by 12 room it is $331 to $993 at $1 to $3 per square foot of wall, which you keep for $150 to $300 of paint and supplies and a weekend of work. The saving gets better across several rooms, because the rollers, tape, and drop cloths carry over and only the paint has to be bought again.
How many gallons of paint do I need for a room?#
Multiply the wall area by the number of coats and divide by what a gallon covers, which HomeGuide puts at 300 to 400 square feet; the paint calculator uses 350. A 12 by 14 room with 8 foot ceilings has 363 square feet of wall after subtracting a door and two windows, so two coats is 726 square feet, or 3 gallons. Ceiling height moves this more than floor area does.
Do I need primer before painting a room?#
Over bare drywall, over patches, over stains, and over any big color change, yes. Over a sound existing finish in a similar color, no. Primer costs $15 to $30 a gallon and is the difference between a color that looks even and one that shows every repair through it. Going dark to light is the case where skipping it costs more than it saves, because it turns two finish coats into three.
