Can't create a custom page size
I'm trying to create a custom size document in Word for using as the
basis for artwork. I need it to be 21.2cm x 15cm. Word lets me create
a custom size but because it's so close to A5 (14.8 x 21) it
automatically resets it to A5 which is no good to me. From trial and
error it seems that a custom size needs to be at least 6mm bigger than a
set one for Word to accept it. Is there any way to force it to accept
my custom size?
Any suggestions much appreciated.
