I meant to do this ages ago when I had to re-make it anyway, but just continued to forget. ANYWAY
I made a template (here)
page that I'm more than willing to share with anyone who wishes to use it. I know most people probably prefer their own comic page size and what-not, and probably already have one made, but for anyone starting anew or wants something closer to how physical comics are sized, this is meant to be as close to the proper size as I could find, what with conflicting page specifications I found around the internet.
11 x 17 inches (3300 x 5100 px)
10 x 15 trim size
9 x 13.5 live area
PLUS GOODIES like perspective paths to make your perspective grids, folders for each panel and reference material, dummy text areas for the names of Penciller and Inker and whatnot.
Soooo, yeah. Have at it.
