Stud Calculator
Calculate the number of wall studs needed.
How It Works
Studs = ceil((Wall Length × 12) ÷ Stud Spacing) + 1.
Example
For a 24 ft wall at 16 in spacing: ceil(288 ÷ 16) + 1 = 19 studs.
Frequently Asked Questions
What is "on center" spacing?
It is the distance between the center of one stud and the center of the next — 16 in is standard.
Do I need to add for corners and openings?
Yes. This is the basic stud count; corners, T-walls, and openings add extra studs.
What stud size should I use?
2×4 studs suit most interior and single-story walls; 2×6 for exterior walls with more insulation.
