I'm building a 6x10' playhouse/shed, and I've got some lumber that's 10 feet long for the joists. I'm planning to use a 12-foot piece, which I'll cut in half for the sides. To make everything fit nicely with standard siding panels (4x8), I'm thinking of trimming each piece down by 3 inches to accommodate the thickness of the lumber. Does this approach make sense? Is it a common method in such projects, or am I off track?

I would suggest doing the outer joists at 10' and the inside ones a bit shorter at about 9'9". You can frame the ends at 5'9" for stability. Just make sure to mark the first interior joist correctly at 15-1/4" from edge to edge, with the others at 16" apart so your panels align correctly. That will save you some hassle later!
Yeah, it sounds like you're on the right track! Another option is to use 1x lumber at the corners to cover any gaps, so either way can work. It's really about what fits your design best!

Thanks for the tip! Just to clarify, you're saying to connect the first interior joist 15-1/4" from the edge of the outside joists, right? So, if I'm attaching sheathing panels, are you warning me that they might not align properly if I don't follow that measurement?
