The length of the raised access floor area.
Measure the full extent of the raised floor along one axis.
The width of the raised access floor area.
Measure the full extent of the raised floor along the perpendicular axis.
The center-to-center spacing of the pedestal grid, matching the access floor panel size.
600 mm (24 in) is the standard panel grid spacing for raised access floor systems.

How this was calculated
Formula source(s)
- In a stringer-braced access floor grid, connecting bars run between every adjacent pair of pedestals in both directions: horizontal connections = (pedestals along length − 1) × pedestals along width; vertical connections = pedestals along length × (pedestals along width − 1)
Inputs used
- Room Length
- 33 ft
- Room Width
- 26 ft
- Panel Grid Spacing (Standard 0.6m/24in)
- 2 ft
Intermediate steps
- Pedestals along length
- 18
- Pedestals along width
- 14
- Short bay at the wall, along the room
- 1 ft
- Short bay at the wall, across the room
- 0 ft
What this calculation does not cover
- Counts bars, and says nothing about which bar. Understructure load rating — concentrated load, ultimate load, and the rolling load a wheeled cart imposes — belongs to the panel and stringer as a matched assembly, and a data hall grid takes a heavier gauge stringer at exactly the count returned here. The right number of the wrong bar shows up as deflection under a loaded rack cart, never on the packing list.
- The grid is assumed to land on whole modules with nothing in the way. Any room dimension that is not a multiple of the grid spacing leaves a short bay at the wall, which needs a cut-to-length bar or a perimeter support angle rather than a standard stringer — while every column, duct penetration, floor box and ramp deletes bays this rectangle still counts. The two errors run in opposite directions and do not cancel.
- Lateral stability is not a bar count. Above roughly 600 mm (24 in) of free height, and in any seismic design category that calls for it, the understructure needs bolted stringers, braced pedestal lines and base plates anchored to the slab — added hardware and a different pedestal, not more of the same stringer.
