# Reference sheets

Three sheets of standard dimensions and material classes, kept separate from the articles so they can be checked quickly.

*The reference sheets and what each covers.*

| Sheet | What it covers | Units |
|---|---|---|
| [Nominal lumber sizes](https://bkgreenstone.com/reference/nominal-lumber-sizes/) | Nominal call-outs against actual surfaced dimensions | inches |
| [Fastener and pilot sizes](https://bkgreenstone.com/reference/fastener-and-pilot-sizes/) | Common wood screw gauges with their usual pilot and clearance holes | inches |
| [Insulation material guide](https://bkgreenstone.com/reference/insulation-material-guide/) | Material classes by form, usual position and limiting factor | no units - descriptive |

Scroll the table sideways for the remaining columns.
