Estimating Framing Spacing

NOTE-- We retired the BidMagic construction estimating software in 2001. It has been replaced by Goldenseal construction estimating software.

We still include this BidMagic estimating software manual as a convenience for users of our older program. Many features are similar, in Goldenseal estimating.

The BidMagic construction estimating software calculates framing costs, based on the spacing of wall studs, floor joists or roof rafters.

Stud/Joist Spacing

Use the cycle button to enter the spacing (in inches) that you will use most often between studs, joists, trusses or rafters. Stud/joist spacings are displayed in inches, but are stored as studs per foot (16" centers=.75 studs per foot).

NOTE: If you use more than one spacing on the project, use whatever spacing is most common.

Enter the following framing spacings into the BidMagic estimating software:

  • Roofs-- Enter the spacing you usually use between roof rafters or trusses.
  • Ceilings-- Enter the spacing you usually use between joists in independent ceiling framing.
  • Interior Walls-- Enter the spacing you usually use between studs in interior walls.
  • Exterior Walls-- Enter the spacing you usually use between studs in exterior walls.
  • Upper Floors-- Enter the spacing you usually use between floor joists or trusses on the second and higher floors.
  • Main Floors-- Enter the spacing you usually use between floor joists or trusses on the first floor.
