Standard Distance Between Roof Trusses

I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet.

Standard distance between roof trusses.

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. It is the vertical distance between the wall and the top of the ridges. 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. Once you ve calculated the number of trusses you will need you should purchase the lumber.

There is a little misconception about truss spacing and strength. Their defense is our engineers will not allow us to. The distance between trusses. The same concept holds true for roof trusses.

Rafter is the distance between the ridge or hip of the roof to the wall plate of the external wall. The standard spacing is 2. Span is the clear distance between the supports of an arch beam or roof truss. Almost all residential trusses use this spacing.

These standards are as follows. Most are spaced between 18 26 inches apart. 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. A few customers prefer installing the trusses every 16 on center because they believe this will be stronger then every 2.

This makes the roof ready for decking or sheetrock.
