INTERIOR PAINT: The formulas estimates the amount of paint needed for individual walls, all the walls within a room (royal blue in diagram) and a ceiling (light blue in diagram).  Each formula calculates the area to be painted based on the dimensions entered, and then estimates the amount of paint or primer needed for this area.  A gallon of good paint typically covers 400 ft².  A gallon of primer typically covers 200 ft²..

EXTERIOR PAINT: The formula estimates the paintable surface area of a simple house (gabled).  It computes the exterior square footage and reduces the amount by a factor of the number of doors and windows.  Exterior paint is usually recommended to cover 300 ft² per gallon.

PAINT PRICING:  The Paint Price Survey pricing information is for several brands and updated monthly.  The brands include:

Painting Guidance

1. How much paint to do you need?  The calculators on this page will help you compute the amount of paint you will need for the walls and ceiling.  However, you will also need paint for the trim (baseboards, crown molding, chair rails) and for door framing. 
2. How do you want the paint to appear? Color is your first major choice, but then you also have to consider the sheen.  The most common are flat, eggshell, satin, semi-gloss and high gloss.  Semi-gloss and high-gloss are often used in high traffic areas and are more durable for cleaning.
3. Preparing the paint area.
   1. Obviously you want to clear the area and move items that might get in the way or be damaged if dripped with paint.
   2. Use drop cloths to protect items and reduce cleanup work.
   3. Remove items that can be easily removed to reduce trim work.  This includes outlet covers, light switches and vent covers.
   4. Surface preparation is important. 
      • If you're covering a stain, you'll want a product Kilz to stop the stain from going through the new paint. 
      • If you're covering drywall or large patches, you'll want the drywall be be smooth with patches and seams that are spackled and sanded and you'll want to remove the spackle dust with a rag or tacky cloth.
      • In all cases, scrape away old paint that is pealing.
      • Apply caulking around door frames, windows and moldings.
      • Apply painters tape on edges to protect them from paint
4. Paint from the top down.  Start with ceilings and then walls. Once these have dried, then paint windows, doors and trim.  Walls and ceilings are often painted with rollers or spray guns.  Trim work is most commonly done with smaller brushes.
5. Final Touches: After the paint has dried, slowly remove masking tape to prevent paint from pealing away with the tape. Return all removed fixtures.
6. Clean Up: Soap and water is enough for non-oil based paints.  Wash the brushes, rollers and rolling pans.  For oil-based paints, follow the manufactures guidance on the paint cans.  Retain the old paint for touchups in the future if possible.  Otherwise recycle when possible.
