Standard Distance Between Roof Trusses

It is the vertical distance between the wall and the top of the ridges.

Standard distance between roof trusses.

Span is the clear distance between the supports of an arch beam or roof truss. 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. 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. Rafter is the distance between the ridge or hip of the roof to the wall plate of the external wall.

Once you ve calculated the number of trusses you will need you should purchase the lumber. The standard spacing is 2. These standards are as follows. I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet.

A few customers prefer installing the trusses every 16 on center because they believe this will be stronger then every 2. Their defense is our engineers will not allow us to. Almost all residential trusses use this spacing. Putting the trusses into place.

There is a little misconception about truss spacing and strength. The distance between trusses. Most are spaced between 18 26 inches apart. This makes the roof ready for decking or sheetrock.

So the space between rafters can be greater without reducing the maximum span.
