Calculate studs and plates needed for wall framing with door and window adjustments.
Input the wall length and height in feet. The calculator uses these measurements to determine the number of studs needed at your chosen spacing. Standard wall heights are 8, 9, or 10 feet.
Choose 2x4 for most interior walls and non-load-bearing applications. Select 2x6 for exterior walls, load-bearing walls, or where better insulation (R-19) is needed. Remember: "2x4" actually measures 1.5" x 3.5".
16" on center is the standard for load-bearing walls and provides optimal strength. 24" on center uses fewer studs and is acceptable for non-load-bearing interior partitions. 12" on center is for special structural requirements.
Each opening requires extra framing members. Doors need 4 additional studs (2 jack + 2 king). Windows need 6 additional studs (2 jack + 2 king + 2 cripple). The calculator automatically adds these to your total.
Get your total stud count with waste factor, plus plate stock in linear feet. The waste factor (typically 10%) accounts for cutting waste and damaged pieces. Results include breakdown of base studs vs. opening studs.
