Before using the preset

Measure this room without the usual shortcuts

The result above is a worked example using the dimensions and openings shown in the breakdown. Use these room-specific checks before treating it as a shopping quantity.

  1. Measure inside the room at floor level instead of relying on a listing or floor plan.
  2. Count the closet door separately. This preset deducts one entry door, one closet door, and two standard windows.
  3. Treat the ceiling as a separate paint selection if you plan to paint it.

Frequently Asked Questions

How much paint do I need for a bedroom?

A standard 12x12 bedroom with 8-foot ceilings needs about 2 gallons of paint for two coats on the walls. This accounts for one door, one closet door, and two windows. Add an extra gallon if painting the ceiling.

What is the best paint finish for a bedroom?

Flat or eggshell finishes are best for bedrooms. Flat hides imperfections and gives a sophisticated look, while eggshell adds a slight sheen that is easier to clean. Avoid high-gloss in bedrooms as it highlights wall flaws.

Should I use primer before painting a bedroom?

Primer is recommended if you are covering dark colors, painting new drywall, or dealing with stains. For repainting over a similar light color in good condition, a paint-and-primer-in-one product often works well.
