A Project Pack includes a total of 20 board feet of our hand-picked lumber, and you'll get a fantastic assortment of widths (typically between 4'' and 10''), and lengths (between 4' and 8'). Purchase a Project Pack when you need enough wood to make a medium sized project like a coffee table or cabinet. As usual, all the lumber is surfaced on two sides (S2S), and kiln dried.

lumber thickness Lumber Compared
Various lumber thickness as compared to one another
  1. Decide how much board footage you need
  2. Factor in enough to work with! You'll want to arrange grain patterns, sort color, fix mistakes, run test cuts, make finish samples, etc.
  3. 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.
  4. 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.
  5. 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.

board foot formula

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.

Check out our article if you want the full explanation.

If you can cut your own pieces to size, here's how we can help:

  1. Enter requirements into the order form where it says, "Minimum Size Request"
  2. Tell us what you want to acheive or make
  3. You will receive wood that can yeild what you need. (You will create the final size)
  4. 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.

Sadly, wood cannot be 100% guaranteed to be clear on both sides all the time. Most of our lumber is graded "Select" and better, which means it's at minimum 83% clear on one side.

Bubinga furniture project
Review by  SS from Payson, AZ USA
This wood is amazing, and the service from Woodworkers Source was exceptional. It was delivered in superbly packaged materials, to Northern Arizona in 2 days! The wood itself is wonderful. Out of 100 board feet of material, there were only 1-2 boards that had more than 1/4 inch warp or twist over their full lengths. The selection made included mostly wide boards, so that was very helpful for my project! If you haven't tried Bubinga, it is amazing. Tight grained and often difficult to even tell grain direction. However, it sands wonderfully, and a clear finish reveals an almost 3 dimensional glow to this wood. Have fun with it!

Bubinga Bedroom Set
Review by  John Fleming from ,
As usual, the lumber from Woodworkers Source was excelent. I have ordered sepele, volador, cherry, African mahogany, Brizaliam satinwood and have yet to be disappointed with any of the lumber. I do resaw a lot of the lumber for doing lamanating. Jewelery boxes are a favotire of mine, especially done on the bandsaw.Once my bedroom is done, I hope to post a few pictures.

Somebody blinked
Review by  Bill from Camden, DE US
I was surprised to find a twisted board in my last pack of bubinga. Surprised because this is a first from WW Source. I was able to cut it into shorter pieces, so most will be useable in a project. Then, I'll be turning some bubinga pens. The rest of the order was, as usual, above average. I hope the guys picking my 60bf of walnut today got a good night's sleep last night. :-) WW Source is still my favorite lumber store.

Review by  bas from Vestavia Hills, AL United States
I was quite pleased with the wood I received. I don't think I would have picked any better boards if I had been in the store myself! There was even one or two heavily figured boards included. Thanks

Not really what I expected
Review by  vivek sharan from SIMPSONVILLE, SC US States
The wood was not what I expected. After seeing quilts of Bubinga online I expected some more character in the wood but it seems the lumber was cut so that only lesser quilted parts were shipped. That wasn't the worst thought. Since I really have not seen Bubinga lumber before I can blame it on my ignorance. 4 pieces were broken completely and were glued back together. That left a broken lines across those 4 boards. I will have to cut the lines out and join them back in astraight line. out of those 2 of them were chipped badly making atleast 2 sq ft unusable. I will have to throw it. I don't know what you guys were thinking sending these out. What do you think i am going to to with the broken pieces. Luckily the first project only uses 7 sq feet so i am able to proceed. Since it took 10 days to reach i was already way behind my project and had to make do with what was sent. Since I did not have the option to look at it before I was buying I knew I was taking a chance. And then the thickness is not 1 inch but around 2 cm. as a result I was sent 19 sq feet not 20 board feet. Overall very disappointed but I guess at this point I have no option as I have to finish the project.
Woodworkers Source Responds

Broken boards? And you got some boards that were glued together? There's something wrong with that for sure. Did you contact customer service about this? If not, Craig or Jason will be in touch with you shortly. But, yes, we do clearly advertise that 4/4 lumber is not rough cut, but planed smooth to 13/16" thick.
