How to Measure

Measuring Tips

  1. Mount hardware before taking any measurements. The most accurate measurements are obtained when hardware is in place.
  2. To obtain accurate measurements, always use a metal or wooden tape measure. Never use a flexible cloth tape, as they tend to stretch.
  3. Enlist the help of a friend to hold one end of the tape measure in position when taking measurements. An additional set of hands helps speed the process along.
  4. Use a stepladder to reach the top of the window.
  5. Measure each window in the same room; windows that appear to be the same size frequently are not. Use a pencil and paper to record measurements and identify each window.
  6. Double-check all measurements before ordering. Keep your written notes on hand as a reference.
