The Boat Gauging House is a building in Tipton, West Midlands, England.

In order to assess the weight of cargo, boats were initially calibrated.

The "wet" method was done during the building of the boat; the Birmingham Canal Navigations (BCN) used the "dry" method, in which a new or refitted boat was loaded from empty with ton weights, and the resulting freeboard, or "dry inches", as the boat sat lower in the water, was each time noted.

It is built of red and blue bricks laid in English bond, and has a hipped roof.

The interior originally had two docks (since filled in) running west–east, lock gates inside the western doorways, and internal cranes.
