Timber Joist Span Tables

Joist spans refer to the “clear” distance that the joist carries over, rather than the overall length of the piece of timber.
However as well as the distance to be “bridged”, both ends of the joist must be properly supported: therefore a clear span of
3metres will actually require a timber member in the order of 3.3 metres.
