Coats compared
Coats is the input people get wrong, usually by hoping. Same room, one coat to three.

|---|---|
| 1 coat | 1.25 gallons |
| 2 coats | 2.5 gallons |
| 3 coats | 3.5 gallons |
What else matters here
Two and a quarter gallons for the walls. A room this size is usually a master bedroom or a family room, which means the ceiling is very likely getting painted too, and the ceiling is not in this figure.
A 14 by 14 ceiling is 196 square feet, so one coat is 0.56 gallons and two coats is 1.12. Ceiling paint is a different product, flat and heavily bodied so it does not spatter or flash, and it is generally cheaper per gallon than wall paint.
Do the ceiling first, always. Overspray and roller mist land on the walls, and painting the walls afterwards covers all of it. Doing it the other way round means cutting a perfect line twice and living with whatever landed on the finished wall.
What this calculator assumes
- A door is taken as 21 sq ft and a window as 15 sq ft. Deducting them matters on a small room and barely moves a big one.
- 350 sq ft per gallon is the usual figure on a smooth primed wall. Bare drywall, textured walls and deep color changes all drink more, so drop it to 300 if any of those apply.
- Ceilings and trim are not included. Run the ceiling as its own area.

The ceiling first. Roller mist from the ceiling lands on the walls, and the wall coats then cover it. Doing the walls first means cutting the line twice.
