How much bigger is the old "twice up" art compared to standard modern art? The six-panel grid in the lower right is standard modern size. Standard art was 12.5x18.5 until 1967 when the industry moved to 10x15. It's gotten even smaller since then.
Art size interior box is 12.5x18.75 with bleed it's 14.5x22. Paper is available in pads. 20 sheets. Here's the paper I'm using. One pad = one issue, which is pretty handy.
