create identical files for the same project when I use A4 format and Letter format?

[Agnes Sellgren]

I´m working on a project that should be available for US Letter format and Europe A4 format. 

I have a question as I´m not able to ask the first designer of this project how she did it and maybe someone can help? When opeing the two PDF documents I can see they look the same in both formats, for example both have the same word finnisihg on the same page. They look identical layout wise although their dimensions are different. 

But when I open the documents in Indesign, I have US version in Letter format inside the border line and the EU version in A4 format is not inside that border line and when I start to adjust so the text goes inside the borderline it won´t look the same as the US Letter format. Text gets adjustest and pages will look different like different words will end the pages.

So my question here is how can I create identical files for the same project when I use A4 format and Letter format? Please advice

Hi @Agnes Sellgren:

I would use Alternate Layouts to create the two versions in a single file with linked content. See https://creativepro.com/indesign-how-using-alternate-layout/.
