Margins and gutter

The outside margins (top, bottom and the edge away from the spine) must be at least 0.25 in without bleed, or 0.375 in with bleed. The inside margin, the gutter, grows with the page count:

Pages	Minimum gutter
24–150	0.375 in (10 mm)
151–300	0.5 in (13 mm)
301–500	0.625 in (16 mm)
501–700	0.75 in (19 mm)
701–828	0.875 in (22 mm)

Bleed

A picture that should reach the edge of the page has to extend 0.125 in past it. The page in your PDF is then 0.125 in wider and 0.25 in taller than the trim size. If any page bleeds, every page in the file has to be set up with bleed.
