Room Area
To compute the area of a room, Revit Architecture does the following:
■ Finds room boundaries . Many model elements have a Room Bounding parameter. For some elements
(such as walls and columns), the Room Bounding parameter is turned on by default. For other elements,
you must turn on the Room Bounding parameter. (See
Room-Bounding Elements on page 981.) To define
room boundaries where no walls exist, use room separation lines. (See Room Separation Lines on page
982.) You can also change the wall layer at which the room boundary is located. (See Changing the Room
Area Boundary Location on page 991.)
■ Uses the computation height . The computation height is a defined height above the base level of the
room. Revit Architecture measures the perimeter of the room at this height. If a building includes sloped
walls or other atypical features, you may need to adjust the computation height to achieve more accurate
room areas and volumes. See
Computation Height on page 989.
By measuring the perimeter of the room at the defined height, Revit Architecture determines the area of the
room.

Computation Height
Revit Architecture measures the perimeter of a room at a defined distance above the base level of the room.
This distance is the computation height. It is used to compute the room perimeter, area, and volume. By
default, the computation height is 4’ or 1200 mm above the base level of the room (the height of the default
cut plane).
For buildings with vertical walls, the default computation height usually gives accurate results. However, if
a building includes sloped walls or other atypical features, you may need to adjust the computation height
to achieve more accurate room areas and volumes.
