Joist span tables - use these tables to determine lengths, sizes and spacing of ceiling joists. Note: Ceiling joists of the first floor of a two-story structure often serve as floor joists for the second floor. If this is the case with your structure, use the Floor Joist Table to determine maximum joist length/load.

However, for a timber pergola, this pergola beam span is too large. You are at severe risk of sagging. Think of book shelves. Over time, with the weight of books standing on top, they do sag in the middle. 1. Beam Design In beams generally,we start with deflection criteria, as the beam resist load in form of bending moment by deflection. So the first criteria is always deflection criteria. The building size is approx 6.5m wide by 4.5m front to back. My question revolves around the correct joist size for the roof. As far as i can see there is no readily available timber size suitable for what will probably end up being a 5.5/6m overall length.

over a 3.5m span, you’ll be fine with 4×2 (95×47) timber. I’d stick with the 4″ posts though. Where abouts are you? Selco is the best place I’ve found for construction timber by a long way. I may put two layers of plasterboard (and a skim) over them, but that is all the weight they will need to hold. But I don't want sagging or cracking, so my question is: what size timber do I need? The longest span is 3800mm, and the joists are spaces every 350mm. Will I get away with 4" x 2", or do I need something meatier? Thanks, Chris Guys, double check me here, in case my morning brain isn't working well. I'm reading RLW 3m You could use F17 seasoned hardwood for the beam. It would be 2/290x35 laminated together for a max span of 6300 at 10kg/m2 so you would be limited in the future and not be able to increase the load, say with a tin roof or ceiling.
