Framing Basics
Stud Spacing
Standard spacing is 16" OC (on center). Use 24" OC for non-load-bearing walls to save material.
Wall Plates
Every wall needs three plates: bottom plate, top plate, and cap plate for connecting walls and distributing loads.
Headers
Install headers above doors and windows to carry loads around openings. Size depends on span width.
Plywood Sheathing
Standard sheets are 4×8 feet. Plan layout to minimize cuts and waste. Always add 10-15% for cutting waste.
