Ability to change page size moving other pages in spread or...

[7x8]

Helloes,

I have a simple project, a cover for a postcard set. But... I don't know in advance how many postcards will be there, be it 10 or 20 which makes quite a difference for a spine-page width. Is there a way to:

a) change page width within a spread in a way that spread will accomodate to the changes and move pages left and right accordingly (so these magenta pages might be 6 or 12 mm and pages won't overlap after changing the size)
b) create spread with gaps between pages, but export as a pdf without those gaps?
c) create whole project as separate pages and create a spread on export?
d) some other solutions?

Thanks!

On the Pages panel - you can select page and on the bottom left you can click icon and set different size.

Thanks, but it won't work as I need to - unless there's some switch or option I should toggle or turn either on or off.
After changing page size with "Edit page size option" spread gets mangled:

When changing master's size pages overlap:

Hi @7x8 , If you setup your spread in a Facing Pages document, a change in page sizes will keep the spread together. Here I’ve selected the 2nd page in the spread with the Pages tool, and set its width to 12mm in the Transform panel:

If I change the width the spread pages stay together. Looks like your doc is setup with Facing pages turned off.

It would help if we could see how the file is currently set up...
