How Far Apart Are Roof Trusses Normally Placed

Putting the trusses into place.

How far apart are roof trusses normally placed.

Common spacing for trusses on this type of building is often between 2 and 4 feet but trusses built with advanced designs may allow spacing as great as 8 or 12 feet. Typical roof truss spacing means that they are usually about 24 inches from centre which means at the centre of one truss there will be a two foot gap or twenty four inch gap until the centre of the next truss. These standards are as follows. Most are spaced between 18 26 inches apart.

For many traditional stick frame builders trusses spaced 8 feet apart seems unnatural but thanks to the ingenuity of modern engineering it is a very common building design. The same concept holds true for roof trusses. The bay is the space within the truss and the longitudinal joining members are purlins. Their defense is our engineers will not allow us to.

With this design change roof trusses could be placed 12 feet apart making it possible for roofs to support the loads to which they would be subjected. These are typically spaced at certain intervals to provide the necessary support for the roof. With traditional stick frame construction the trusses are usually spaced 2 feet apart. A 10 8 6 and 4 spacing between trusses has been the standard for most types of construction for years.

The trusses should be a little longer than the exact width to allow for overhang and you will need sufficient trusses to mount across the length.
