How it works
- One stud per spacing plus one per wall, two extra at each corner and intersection, and kings, jacks and cripples at each opening.
- Header sizes are rough single-story rules of thumb — check IRC table R602.7 for your loads and spans.
- Add your supplier's unit prices to any line for a cost estimate; tax and markup are optional.
How to measure
- Measure each wall's length and plate-to-plate height. Enter rough-opening widths for windows and doors.
Estimates only. Coverage, sizes and waste vary by product and job — verify with the manufacturer's specs and your local building code before ordering.
