How these estimates are built
- Start from something you can measure. Room dimensions, wall area, linear feet of fence — never a guess at total square footage.
- Subtract obvious waste. Doors, windows and openings come off the top. Deep color changes and texture get added back as extra coverage.
- Round to a unit you can buy. Whole gallons, boxes of tile, bags of concrete — with the leftover math shown so you can buy a quart instead of a fourth gallon.
Material prices change. Each guide lists the price range it assumes and the date it was last checked, so you can see how far off your local store might be.
