Storage / Fit-first field guides
These guides begin with the part of the room that cannot negotiate: an appliance gap, a plumbing run, or a hallway route. Compare listings only after that constraint is measured.

Start at the tightest fixed point, then follow every opening, turn, and motion the storage has to clear.

Storage comparisons
The narrowest listed option is 4.9 inches wide, but the right cart is the one that clears the narrowest point of your gap, baseboards, hoses, and the full pull-out path.
Measure the cabinet opening, P-trap and valve footprint, usable height under the pipes, and the full pull-out path before choosing an organizer. A low price cannot compensate for missing assembled dimensions in a measured cabinet.
Cabinet depth alone is not enough: measure the remaining passage, front-door swing, flip-drawer opening envelope, baseboards, and wall-anchoring position. A cabinet without a listed assembled depth is not approved for a measured hallway.
