What is the standard spacing for wall studs in residential construction?
Answer: 16 inches on center
Residential wall studs are typically spaced 16 inches on center, though 24-inch spacing is also code-compliant in some applications.
Which type of header is most commonly used above a load-bearing door opening?
Answer: Double 2×10 with 1/2-inch plywood spacer
A doubled 2×10 with a 1/2-inch plywood spacer is a common load-bearing header because it matches the wall thickness and provides adequate structural support.
What is the purpose of a cripple stud in wall framing?

What is the minimum bearing length for a floor joist resting on a wood sill plate?
Answer: 2 inches
IRC and most building codes require floor joists to bear a minimum of 1.5 inches on wood and 3 inches on masonry, but 1.5 inches is the wood minimum per IRC R502.6.
Which framing member runs perpendicular to floor joists to prevent rotation and increase rigidity?
Answer: Bridging or blocking
Bridging (either solid blocking or cross-bridging) is installed perpendicular to joists to resist rotation and distribute loads across multiple members.
