· Measure the room (s) you’ll be painting,
  rounding up to the nearest foot. You
  want to get slightly more than you need
  to ensure you’ll have enough (if coverage
  rate is not exact) – and that you’ll have
  some left over for touch up. For wall
  paints – and especially custom colors,
  never change gallons in the middle of a
  wall – always at the corners or edges.

  For help with calculating, go to our
  PQI Calculator
 

· For trim, decide on the number of door surfaces you’ll
  be painting (count two if you’re painting both sides).
  Measure the height and length of all molding, then fill
  in to our Trim Calculator.
