# Dimensional lumber: actual sizes of 1x2 to 6x6, 8 to 16 ft (2x4 = 1-1/2 × 3-1/2 in)

> What are the actual dimensions of a 2x4?

- Category: Hardware › Building materials
- Kind: Standard part
- Basis: US softwood lumber standard (DOC PS 20), dry dressed sizes: nominal 1 in = 3/4 in, 2 in = 1-1/2 in, 4 in = 3-1/2 in; widths to 6 in lose 1/2 in, 8 in and up lose 3/4 in
- Page: https://xemstudio.com/objects/dimensional-lumber/ · JSON: https://xemstudio.com/api/geometry?object=dimensional-lumber · Plain text: https://xemstudio.com/objects/dimensional-lumber/sheet.txt

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Drawn square-edged at the dressed size; real boards have eased (rounded) edges about 1/8 in.
- Pre-cut studs: 92-5/8 in (with a bottom plate and a double top plate makes an 8 ft wall) and 104-5/8 in (9 ft).
