How lumber sizes are described
- Rough (4/4, 8/4…)
- Hardwood thickness in quarters of an inch as sawn, before surfacing. 4/4 = 1" rough.
- Surfaced (S2S/S4S)
- Thickness after planing. 4/4 typically finishes at 13/16" or 3/4".
- Nominal vs. actual
- Construction lumber is sold by nominal size; a 2x6 measures about 1-1/2" x 5-1/2".
- Random width / length
- Most hardwood is sold as it comes from the log — widths and lengths vary within a range rather than being fixed.
