How To Measure: Entrance Door Systems

All measurements must be taken from the exterior of your home

  1. Measure the width of your door system from the outer end to end of the door system. This point is where the outer frame and brickmould of the door system meets either the brick or siding.
  2. Measure the height of the door system from the bottom of the exterior sill just above the floor level to the top of the door or transom above the door where the outer frame and brickmould of the door system meets the brick or siding.
