- Decide how much board footage you need
- Factor in enough to work with! You'll want to arrange grain patterns, sort color, fix mistakes, run test cuts, make finish samples, etc.
- Lumber comes in random widths and lengths. If you need special size considerations, please let us know by using the "Minimum Size Request" box in the order form or by confirming your needs by phone or email.
- Expect your final amount of footage to change slightly. Buying by the board foot is an exercise in estimation, therefore we don't know the precise amount of footage you'll receive (and be billed for) until we physically select the wood for your order.
- We want to get your order right! So we may need to contact you for clarification. Please use a good phone and email during checkout.
This is the unit of measurement for hardwood lumber when it's bought/sold in random widths and random lengths.
Board footage is a measurement of volume, and it's abbreviated Bd. Ft.
One board foot is equal to 144 cubic inches.

It's a fraction that refers to rough (RGH) sawn thickness of lumber, and it tells you approximately how many quarters of an inch make up the thickness.
Surfaced lumber is thinner because it started out as rough sawn but it's been planed smooth. Planing removes thickness.
Rough Sawn (RGH) | Surfaced (S2S) | |
4/4 | ~1" | 13/16" |
5/4 | ~1-1/4" | 1-1/16" |
6/4 | ~1-1/2" | 1-5/16" |
8/4 | ~2" | 1-13/16" |
12/4 | ~3" | 2-13/16" |
Unless otherwise specified, our lumber is "Surfaced 2 Sides" or S2S for short.

If you can cut your own pieces to size, here's how we can help:
- Enter requirements into the order form where it says, "Minimum Size Request"
- Tell us what you want to acheive or make
- You will receive wood that can yeild what you need. (You will create the final size)
- We may need to contact you for clarification
You will cut and/or join your material to create the finished sizes you need. We'll pick out wood that will give you enough to do that. For this reason, the final amount of footage you receive in your order will be slightly different, and your final billed charge will be different.
If you want to only buy pieces of an exact size, that will be sold differently. Please contact us for a custom quote.
