Text width; text height

Hello blue fox.

You told Théo the method to print on non-standard paper. He wants to print on standardized paper, but by adjusting the margins so that the text fits into a rectangle of 20 x 12 ...

I would therefore suggest that if he uses A4 paper, he should set it to landscape orientation, and adjust the margins to 0.5 at the top and bottom, and 1.5 on the right and left; he thus gets a text area of 20 in height and 26.7 in width; he just needs to go to PAGE LAYOUT/Columns/Two.
And to finish the adjustment, go to PAGE LAYOUT/Columns/More Columns and increase the spacing (1.25 by default) up to 2.7.
Best regards.
Retirement is great! Especially in the Caribbean ... :-)

Hello Théo and Raymond PENTIER

I make my "mea culpa" and I flagellate myself because indeed, having answered too quickly, I indicated how to set "non-standard" paper dimensions.
That said, I agree with Raymond's method.
In general, I summarize it by saying: "display in Portrait or Landscape
as needed, then display the ruler to stay within the desired dimensions and adjust the margins as specified by Raymond PENTIER.

Have a good day to both of you and to the whole forum.
