Re: Indesign Templates - Design advice - Childrens Book - 19 x 19

The settings are all part of the document setup, which you can define when you setup the new file. From InDesign, go File > New > and then you want to input the size as 19cm x 19cm. The margins and bleeds will be defines by the company printing the book for you, but normally a 1/4" margin and a 1/8" bleed are acceptable. Again, check with the printer, as sometimes they require a larger size on either the bleed or margin.
