How do I force the chapter start (Heading 1) pages on odd page numbers?

Thanks.

As a style attribute, all you can specify is "Page break before," unfortunately.

You'll have to manually insert an Odd Page section break. (You should also enable "Mirror margins" and/or "Different odd and even" in Page Setup; this ensures that Word correctly inserts a filler page as needed.)

Stefan,

What does and/or mean?

I found Mirrored page. It increases pages by 150, which means I have to check each page for proper breaks ( i have tables and diagrams). It looks like I have to do it.

I found Odd Page, Insert section break... this i have to do for each chapter start (heading 1).

I did not find this one: "Different odd and even"

Thanks.


Thanks.

And/or means at least one of the two options I mentioned. You'll find "Different odd and even" on the Header & Footer Tools Design tab, which activates if you double-click a header in Word.
