Importar Word A4 para ID 13x21

As in the prior thread, all you can do is import the Word document's elements into an InDesign document of that page size, and then arrange and scale up each element until you have the new or duplicated layout you want.

There is no simple way to import a Word doc and have it both be a perfect duplicate and scaled up in InDesign.

The one shortcut would be to export it from Word to PDF and then either place the PDF on the larger InDesign page, scaling it up as necessary, or simply print it to a larger page size using scaling from Acrobat to the printer. Neither PDF would be editable, though, just a static file for further export or printing.

If you want an editable InDesign document, the first method is the only one.

If you don't want to edit it in InDesign, it's not clear why you are importing it at all.
