Hi I want to build a mezzanine in my garage and I the span is 12 feet wide by 10 feet long and I would like to know what would be better to put 2x8 or 2x10 at every 16 or 12 inch apart. I'm asking because I'm building this mezzanine above the garage door opener so I have a clearance of max 4 feet so the thicker I go with the joist the more space I loose so I would like to have a good load baring capability with a maximum space.
Thanks for you help.
Depends on the intended load. Google SpanCalc - it's an online joist span calculator from the Canadian Wood Council. Do some reading on design loads before you plug in the numbers, and make sure you use the correct tab for the wood species commonly sold in your area.
RI had a thought. If you used a beam and joist hangered.......the joist.
I tried my best to show you the layout but unfortunately we can't upload document. I think to make sure that it's solid I will put 2x10 at every 12" along the width so I can get the wall on each side (Left & right) using joist hangers like jloomis said. Plus there shouldn't be a problem for 2x10 on a span of 12' 2".
12' 2" |-------------------------------| |-------------------------------| |-------------------------------| |-------------------------------| 10" |-------------------------------| |-------------------------------| |-------------------------------|Thanks guys and I'm still open to suggestion
