The stacking plan displays the measured area of each suite as opposed to the marketing area. The measured area is intended to be the "official" square feet of a suite, certified by a measuring company such as BOMA, while the marketing area is what is being offered as available. They are usually the same, but not always. The measured area does not appear on the leasing pages, and is for internal use only. It is the measurement that is used in creating most reports.
