I have a friend that is building a small barn and wants me to mill the boards for the siding. Its going to be board and baton. He's not sure if he wants me to mill them to 3/4" or 1" thick.
Is there a typical thickness that siding is milled at.
Thanks!

I think it depends on the size and scale of the barn and the girt spacing. If it's an 8-10 ft wall with girts 24-30" apart I'd go with 3/4 or 13/16. Older barns with 4ft or so girt spacing, I'd go 1" on the siding. Just my .02.

I've been cutting mine (personal use) at 7/8", which is easy to do with no simpleset by dropping down 1" at a time on the regular inch scale.

Putting it down with screws or nails?  Width of bat makes a difference in splitting, as increasing thickness will require longer nails or screws. Nails generally the shank gets bigger as it gets longer. Screws are a little bigger to begin with. Pre drill the holes to keep this from happening.

I am building a board and batten shed myself, 12 x 18 and I am planning on using ring shank galvanized nails. I cut mine 4/4. For the flooring, I cut them 5/4.

Ring shank nails do hold well. Thing is, they're called ring shank. With battens the nails go through the batten then air equal to the siding thickness and finally into the girt or strapping, so a three inch nail would only be one inch into the underlying nailing surface. Normally you need 1.5" penetration for proper holding power, so with 1" siding and 1" battens you would use 3.5" nails. That's why I use screws on the battens and rink shank nails on the siding and things stay tight. I usually saw my battens a little thinner than the siding also. Just throwing it out there as food for thought.

There is alot to consider, most of it not important.  1" is the tradition.  3/4 is all you need. Carpenter bees: some say they don't bother 5/8".  The type of wood, may crack and curl if sawn in summer and sawn too thin especially wide boards.

Moody,

   I had never heard that about carpenter bees. Interesting observation.

Their tunnel won't fit  :). 5/8x6 poplar clapboard was very common here.
I usually saw a scant 1-1/8 and plane to 7/8 for B&B with 3/4 thick battens.

I myself like the looks of one inch boards. But once in place, who can tell. 
I also like the looks of a full 2x whatever.

Same here.
To my customers I typically recommend a 7/8" board thickness and a 3/4" batten thickness so as to allow use of a standard nail gun for both the boards and the battens.

Milled all the EWP 2 years ago for my son to build a garage (columns are oak).  10 inch wall boards were milled at 1 1/16.  After better part of a year of air dry they shrunk to 1 x 9.5.  A bit more expensive but using decking screws to secure.  Battens will be 3/4 x 3 with deck screws as well.  Had him run a water board of PT on the bottom to reduce rot from splash.  Also priming ends.  Getting there.
