Will it get through the door?

A doorway is easy and everybody checks it. The corner is what catches people, because the constraint is not either corridor’s width — it is the pair. Two 5 ft corridors meeting at a right angle will not pass a 12 ft item, however large the room at either end.

Three tape measurements, before anybody is standing in a corridor with a piano. A venue’s own dock drawings beat this.

The thing, and the route

A 16 ft bar top does not reach the room. It stops at the tightest right-angle turn, and it stops there whatever the room measures.

The narrowest doorway
Clear
A 16 ft bar top passes a 3 ft × 7 ft opening. A doorway only ever sees the cross-section, never the length.
The tightest right-angle turn
Stops here
A 16 ft bar top is 16 ft, and a 5 ft into 5 ft turn takes up to 9.1 ft. The corridor widths at either end do not help; the worst moment of the turn decides it.

The corner is the one people do not check. Two 5 ft corridors meeting at a right angle will not pass a 12 ft item, however large the room at either end — the worst moment of the turn decides it, not the corridor widths on their own. A venue’s own dock drawings beat this.
