Room Area and Volume

Revit LT can calculate the area and volume of rooms and display the information in schedules and tags.

Topics in this section

About Room Area
Room areas display on the Properties palette, in tags, and in schedules for rooms.
About the Computation Height for Rooms
Revit LT measures the perimeter of a room at a defined distance above the base level of the room. This distance is the computation height.
About Room Volume
Room volumes display on the Properties palette, in tags, and in schedules for rooms.
How Room Volume is Computed
Learn how Revit LT determines the volume of a room.
About Room Height
Revit LT uses the height of a room to compute its volume.
About Ceilings and Floors in Room Volume Computations
If the room height does not reach upper or lower room-bounding elements, Revit LT uses the specified upper and lower boundaries to compute the height and the resulting volume of the room.
Situations That Can Affect Room Volume Computations
In certain cases, the room volume that Revit LT computes may not reflect unique features of a room.
About Defining the Upper Boundary of a Room
Together, the Upper Limit and Limit Offset parameters define the upper boundary of the room.
About Defining the Lower Boundary of a Room
Together, the Level and Base Offset parameters define the lower boundary of a room.
Change the Room Area Boundary Location
By default, Revit LT computes the room area using the wall finish as the boundary. You can change the boundary, specifying the wall center, wall core layer, or wall core center.
Change the Computation Height for Rooms
If a room includes a sloped wall, consider adjusting the computation height to produce more accurate results for the room area and volume.
Enable Room Volume Computations
To see room volumes on the Properties palette, in tags, and in room schedules, enable volume computations.
Change the Room Height Graphically
In a section view, you can change the height of a room graphically by adjusting the upper and lower boundaries of the room.
