1x4x96:
15.5" x 3 (steps)
10.5" x 2 (side-tops)
7" x 2 (side-bottoms)
14" x1 (back)
2x4x96:
16" x 3 (steps)
7" x 2 (side-tops)
10.5" x 2 (side-bottoms)
13" x 1 (back)
Notes:
- cut the back piece last, after confirming everything else fits flush (you may need to adjust the length of the back piece)
- our 96" planks were actually 96.5" which meant we had an inch and a bit leftover, depending on the accuracy of the cuts
- thinner 1x4 planks obviously split more easily than thicker 2x4 planks so larger pilot holes should be made
- angled cuts introduce errors on pocket holes; ensure edges are flat before placing in jig
- dowels are difficult to flush cut, try wood filler
