I'm building a freestanding garden pergola, and I think I've messed up on the cross beam sizes ☹
The posts are 100x100mm and I ordered 88x32mm cross beams. The slats are also 88x32mm and its all in green oak.
The largest span is 2.4m and I'm not sure now that my cross beams are big enough to cover that span without sagging in the middle over time.
Am I likely to get away with it. Or should I replace them with 125x50mm cross beams ?
And if I do replace the cross beams for bigger ones. Will I also have to replace the slats with bigger ones to avoid it looking odd ?
