Scale model lumber (1:12, or “One Inch Scale”) in Juniper wood, which is between Basswood and Balsa in hardness with varied coloring and a pleasant scent. The full set option has 331 pieces, all over 13 inches long.

This is the full set as shown in the photos:
(22) 1x1's (trim and spacers)
(22) 2x2's (spindles)
(22) 2x3's (blocking, drywall backing)
(44) 2x4’s (studs, etc)
(22) 2x6’s (studs, etc)
(22) 2x8's (studs, stairs, joists, rafters)
(22) 2x10's (stairs, joists, floors)
(22) 2x12’s (stairs, joists, floors)
(20) 4x4’s (posts)
(10) 4x6's (posts)
(6) 4x8's (posts, beams)
(6) 4x10’s (beams)

These 331 pieces fit nicely into a Medium Flat Rate box, which insures that they get to you right away with free shipping. The sample pictures of models I’ve built for myself show how well these can be used for a variety of projects.

The individual sizes listed are a selection of the most popular sizes; all are available individually if desired.

Now let's talk about dimensions.

Dimensional lumber you get at the store, such as a 2x4 is neither 2 inches thick nor 4 inches wide. Furthermore, the 'missing part' varies depending on the size: a 2x4 is 1-1/2" x 3-1/2", while a 2x8 is 1-1/2" x 7-1/4". Taking it down to 1:12 scale is not as easy at it seems; the dimensions of many suppliers are approximations, not accurate cuts. For example, on my fourth picture, look at the crack between the two boards above the window. That is exactly the 1/2" space between the headers you would get in real life.

So here are both the real life dimensions and how they translate to model lumber to the nearest 64th:

1x1 is 3/4” x 3/4”
The model dimensions are 1.696/64 x 1.696/64
The decimal equivalent is .0265 x .0265
2x2 is 1-1/2” x 1-1/2”
The model dimensions are 1/8 x 1/8
The decimal equivalent is .125 x .125
2x3 is 1-1/2” x 2-1/2”
The model dimensions are 1/8 x 13/64
The decimal equivalent is .125 x .208
2x4 is 1-1/2" x 3-1/2"
The model dimensions are 1/8" x 19/64"
The decimal equivalent is .125 x .292
2x6 is 1-1/2" x 5-1/2"
The model dimensions are 1/8" x 29/64"
The decimal equivalent is .125 x .458
2x8 is 1-1/2" x 7-1/4"
The model dimensions are 1/8" x 39/64"
The decimal equivalent is .125 x .604
2x10 is 1-1/2" x 9-1/4"
The model dimensions are 1/8" x 49/64"
The decimal equivalent is .125 x .771
2x12 is 1-1/2" x 11-1/4"
The model dimensions are 1/8" x 15/16"
The decimal equivalent is .125 x .938
4x4 is 3-1/2" x 3-1/2"
The model dimensions are 19/64" x 19/64"
The decimal equivalent is .292 x .292
4x6 is 1-1/2" x 5-1/2"
The model dimensions are 19/64" x 29/64"
The decimal equivalent is .125 x .458
4x8 is 1-1/2" x 7-1/4"
The model dimensions are 19/64" x 39/64"
The decimal equivalent is .125 x .604
4x10 is 1-1/2" x 9-1/4"
The model dimensions are 19/64" x 49/64"
The decimal equivalent is .125 x .771
4x12 is 1-1/2" x 11-1/4"
The model dimensions are 19/64" x 15/16"
The decimal equivalent is .125 x .938
Note that from here down, beams have a quarter inch more than stud dimensions. A 4x8 is 7-1/4” on the wide side, and a 6x8 is 7-1/2” on the wide side.
6x6 is 5-1/2" x 5-1/2"
The model dimensions are 29/6" x 29/64"
The decimal equivalent is .458 x .458
6x8 is 5-1/2" x 7-1/2"
The model dimensions are 29/64" x 5/8"
The decimal equivalent is .458 x .625
6x10 is 5-1/2" x 9-1/2"
The model dimensions are 29/64" x 51/64"
The decimal equivalent is .458 x .792
6x12 is 5-1/2" x 11-1/2"
The model dimensions are 29/64" x 61/64"
The decimal equivalent is .458 x .958
8x8 is 7-1/2" x 7-1/2"
The model dimensions are 5/8" x 5/8"
The decimal equivalent is .625 x .625
8x10 is 7-1/2" x 9-1/2"
The model dimensions are 5/8" x 51/64"
The decimal equivalent is .625 x .792
8x12 is 7-1/2" x 11-1/2"
The model dimensions are 5/8" x 61/64"
The decimal equivalent is .625 x .958
Good hardwood flooring is 3/4" thick, in varying widths.
The model dimension is 1/16"
The decimal equivalent is .0625
5/4x6 Decking is generally an inch thick.
Its model dimension is 5/64" x 29/64"
The decimal equivalent is .083 x .458

These are carefully made on the tablesaw, not some fancy equipment, so you will get a bit of variation. How much? About exactly what you get if you are a builder and buying real lumber. That should help with the model realism.

And of course I’ll help you out with any kinds of issues or questions.
