Hallway paint calculator

A typical hallway needs about 1 gallon + 3 quarts

Based on a standard 4 × 15 ft hallway with 8-ft ceilings, the walls work out to about 304 sq ft after subtracting 0 doors and 0 windows. A standard two-coat repaint needs roughly 1 gallon + 3 quarts of quality interior paint. The recommended finish for a hallway is satin — more on why below.

Satin Holds Up To Daily Contact

Hallways take more physical abuse than any other interior surface. Bags, shoulders, pet tails, and dragged furniture all hit these walls. Flat paint burnishes and scuffs within weeks, and eggshell is only slightly tougher. Satin is the practical floor for a hall: it wipes clean, hides hand-oil shine, and survives a damp cloth without leaving a polished spot. In a busy family hallway, semi-gloss on a chair rail or wainscot buys even more durability where hands and shoes land most.

Color In A Windowless Corridor

Most halls get no daylight, so the color you pick lives entirely under artificial light. Cool grays go flat and gloomy here; mid-tone warm whites, soft greiges, and light putty tones stay alive under bulbs. Test a sample at night with the hall lights you actually use, not in the bright bathroom next door. If the hall is long and dark, go a shade lighter than feels right on the chip — paint always reads darker on a full wall with no window to bounce light back.

Stairwell Walls Need A Plan

Where the hall meets stairs, walls can run 12 to 18 ft to the upper landing, and you cannot safely reach those with a straight ladder over open steps. Either rent an adjustable articulating ladder or set a plank between a tread and a stepladder on the landing, and cut in the high triangle before you roll. Measure to the tallest point and use that as the ceiling height in the calculator; you will slightly over-buy, which is correct because the angled cuts waste paint.

Trim, Doors, And Sequence

Halls are mostly door casings, baseboards, and the odd closet, so trim is a bigger share of the job than the square footage suggests. Paint the trim and doors first in semi-gloss, let them cure, then tape and roll the walls — cutting wall color to a hard trim edge is faster than the reverse. Keep a labeled cup of leftover satin in the closet; hallway walls are the first place in the house you will need a touch-up.

How the hallway paint math works

Wall area is perimeter × ceiling height: (2 × 4 + 2 × 15) = 38 ft of perimeter, times a 8-ft ceiling, equals 304 sq ft of gross wall. We subtract 21 sq ft per door and 15 sq ft per window, leaving about 304 sq ft of paintable wall. Multiply by the number of coats, divide by a coverage rate of about 388 sq ft per gallon, and round up to the nearest quart — that is the number you take to the store. Change any input in the calculator above and it recalculates instantly.

Paint needed by coats

Two coats is the right default for almost every repaint. Use one coat only for a same-color refresh, and three for dark-over-light changes or vivid colors that cannot hide in two. The ceiling adds 60 sq ft (length × width) when you choose to paint it — usually a separate flat-white product, so most people buy a dedicated gallon for it.

What it costs to paint a hallway

Doing it yourself, the paint for two coats runs about $70–$123 (roughly 1.75 gal at $40–$70 a gallon), plus $50–$100 in supplies — rollers, brushes, tape, trays, and a drop cloth. That is your whole cost if you bring the labor.

Hiring a painter changes the math: most pros charge $2–$5 per square foot of floor area, so a 60 sq ft hallway lands around $120–$300. Labor is 75–95% of an interior bill because prep, cutting in, and cleanup eat the hours. For a full paint-plus-labor breakdown, use the paint cost calculator.

Paint cost by brand

Coverage is similar (about 350–400 sq ft per gallon) across the major interior lines, so the price tier is what moves your bill.
