I am building a small 8' x 10' shed with OSB wood panel on the sides.
Could someone tell me which side of the OSB wood panel should face
outside or does it matter. The sides will eventually be finished in
vinyl siding as money permits.

Don'r recall the printing as to which side goes "up" or "out", but the last
OSB I used for roof sheathing, we put the side with the LINES on it "up".
The lines are there to mark both 16" and 24" centers so you have guides for
nailing it down.
As noted by someone else. its not waterproof in the least and will fall
apart really fast if it gets wet so cover it immediately. For exterior
walls it won't matter which side is out. If you use it for interior
walls and plan to paint it as I did then I'd use the smoother side (the
one with the writing) as the surface to paint. It DEFINATELY needs a
sealer though but looks great once sealed and painted bright white - for
a shop. FWIW, corrugated galvanized metal sheets are like $5 ea at HD
for a 2x8 piece. I used this for my roof, 30# tar paper under that &
7/16 OSB under that.
BTW, if used as the decking for the roof, the side with the small
dimples goes up so you won't slide off the roof when papering and
shingling or whatever other roofing material you use. The smooth side
is slicker than snot on a doorknob, or cat shit on a linoleum floor - if
