Most shop layouts fail at the infeed, not the machine. Wood is long; machines are not. Plan the path of the longest board first and the floor plan almost draws itself.
Start with stock flow, not machines
Trace a board from the door: break down, face and edge, thickness, joint, sand, assemble. Machines go on that line in that order — every crossing of the line is a future traffic jam.
Give the saw its diagonal
The table saw needs infeed plus outfeed longer than your longest rip, and the diagonal of the shop is usually the only place that exists. Put the saw there first and let everything else negotiate.
Jointer and planer share an aisle
Boards bounce between facing and thicknessing, so keep those two beds parallel and a single step apart. A combo machine solves the dance in one footprint.
Leave the walls for what stands still
Benches, sharpening and storage live against walls. Machines that eat long stock need air on both ends — the middle of the floor is theirs.
