You're right. I never even considered non-interactive scanning before...

But I do :-) These lines in snapscan.c provide a clue:

#define DEFAULT_BRX SANE_FIX(152.0) /* 6x4 photo size */
#define DEFAULT_BRY SANE_FIX(101.0)

It is the default size if none is specified. "scanimage -h" lists all
device-specific options. You can (among other things) set the corners
of the scanning area, or try one of the predefined paper sizes, e.g.:

scanimage --predef-window 8.5x11
