I'm building a shed and have experience with DIY projects like framing and roofing, but I have a question about window framing that might seem basic. I'm aware that I need to include a king header and cripple studs, and I want to make sure I leave enough space for the window when framing with 2x4s. How much extra space should I plan for? Should the framing be exactly the size of the window casing, or a bit larger to allow for adjustments? Also, if I'm using a reclaimed window, do I need to reframe it with something like 1x4 before installation?

Definitely give yourself some wiggle room! Shimming the window helps you set it perfectly, and trust me, the trim will cover everything you need it to.
Thanks for the advice, everyone!
When I used to frame houses during college, our guideline was to leave about 5/8 to 3/4 inch of space on each side of the window. This extra room is great for shimming to get the window level, and remember, the trim will cover any gaps. Just make sure you allow for that little extra!
I second that! I usually go with 3/4 inch all around (so 1.5 inches taller and wider) because half an inch just isn't quite enough to ensure that the window sits level.
