About Lumber Sizes & Shipping Length Restrictions

Premium Walnut lumber comes in random sizes, but within certain ranges. Here's what you can expect.

4" to 7" Widths

Price shown is for a random selection of widths within this range. You can request specific widths or add a straight edge rip in the order form.

6' to 12' Lengths

This is the range of lengths that we might have in stock. We always try to ship the longest possible lengths, but to make it easier on you and us, request length ranges in the order form.

Length Shipping Restrictions
84" (7') long max
We always try to ship the longest lengths possible, depending on the quantity you order and what we have available at that time. But 7' is the longest length we can reasonably ship by UPS & FedEx
8' to 12' long is possible
8' and longer can be shipped truck freight, but this method is usually economical only for shipments that are at least 350 lbs (approx 100 board feet); Please contact us if you have questions.

1-5/16" Thickness

Also known as 6/4, S2S. Surfaced 2 sides (S2S) from rough sawn lumber. You should be able to yield approximately 1-1/4" thickness after you flatten, plane, shape or sand your project parts to fit your project..

Lumber 101: What to Know About Hardwood Lumber

lumber random widths Random Widths
You will cut and/or glue to create the sizes you need
rough sawn vs surfaced lumber Surfaced Smooth S2S
We buy rough sawn lumber and have it surfaced 2 sides (S2S) so you're ready to work
rough sawn vs surfaced lumber Kiln Dried
We stock kiln dried lumber and store it in a protected warehouse
rough sawn vs surfaced lumber 83%+ Clear
Unless stated otherwise, we stock Select & Better graded lumber that's at least 83% clear one side
  1. Pick a wood you like
  2. Decide how much you need
  3. Give us your specs (if you have any)

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 blog for 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.

Premium black walnut 6/4
Review by  John from Pineville, Louisiana
I ordered premium black walnut. While the boards were nice, one of them had a fairly large knot in the center and prominent snipe -- not what I expected for "premium" boards. I will be able to use the wood, but I expected somewhat better quality. Maybe I expected too much. Service and prices, however, continue to be very good and I actually received MORE than I expected. Very happy about that.

Nice Order
Review by  Tom from MA
This was my 1st order which also included Purple Heart. Both the Black Walnut and the Purple Heart were delivered blemish free and undamaged, neither too dry nor too much moisture. It was a pleasure and I will order more products in the future. Based on my first order, I would recommend Woodworkers Source, especially for exotic woods.

High Quality Lumber
Review by  Bob from PIttsburgh area
The walnut was nicely figured, making it very suitable for a book ended cabinet door. It arrived promptly and was well protected in shipment with an outer layer of cardboard and an inner layer of plastic.
