Framing 101 · The Field Guide

Know what’s inside your walls.

Everything behind your drywall, in plain English. Thirteen short pages covering the vocabulary you will hear on site, what each member actually does, and the one concept that explains all of it.

Start Here · The One Concept That Matters

The Load Path

Every pound your house weighs has to travel an unbroken path to the earth. Good framing is really just the discipline of never interrupting that path. Read this one first — it makes every other page on this list obvious.

ROOF → PLATES → STUDS → FLOOR → FOUNDATION

The vocabulary

Vertical

Stud

The workhorse. Vertical 2×4 or 2×6 members at 16″ on-center that carry load down and back every finish surface.

2×4 / 2×6 · 16″ O.C.
Horizontal

Top & Bottom Plates

The lumber that caps and anchors a wall. The double top plate ties walls together and spreads load across the studs.

(2) 2× TOP · PT ON CONCRETE
Over Openings

Header

The beam over a window or door. It picks up the load the missing studs would have carried.

SIZED BY SPAN + LOAD
Engineered

LVL Beam

Laminated veneer lumber — stronger and straighter than sawn lumber. The go-to for wall removals.

1¾″ PLIES · 2.0E
Floors & Ceilings

Joist

The horizontal members framing a floor or ceiling — and the reason your floor does or does not bounce.

SAWN OR I-JOIST
Roof · Cut On Site

Rafter

Sloped roof members cut one at a time. What makes vaulted ceilings and usable attics possible.

BIRD’S-MOUTH SEAT
Roof · Factory Built

Roof Truss

Pre-engineered, craned into place, fast and economical — and never, ever cut without an engineer.

NEVER CUT A TRUSS
The Skin

Sheathing

OSB or plywood over studs and rafters. It braces the frame against wind and racking. It is structure.

NAILING SCHEDULE IS EVERYTHING
Opening Support

King & Jack Studs

The pair that frames every opening — one full height, one cut short to carry the header.

DOUBLED ON WIDE SPANS
Short Members

Cripple Stud

Short studs above headers and below sills that keep the 16″ layout marching through the opening.

LAYOUT KEEPERS
The Perimeter

Rim Joist

Caps the ends of every floor joist, carries wall load down — and is the number one rot and air-leak location.

ROT & TERMITE HOT SPOT
Layout

16″ On-Center

The standard spacing. It exists because 48 divides by 16, so every sheet edge lands on lumber.

48 ÷ 16 = 3
