The best way to determine the size of an Andersen® window or patio door is to measure the unobstructed glass dimensions, or the visible glass surface you can see and touch. If the Andersen product is a standard size, then match the visible glass dimensions to the unit size in the size charts below. Directions on how to measure the visible glass can be found in How to Measure Glass in Your Andersen® Window or Patio Door. After obtaining the visible glass width and height measurements from the window or patio door, match the dimensions to the standard charts linked below.
