How did you make it?
I would recommend to use 3 pages in a spread. Change the size with document setup and with page tool.
Do you mean you want to change the size of a panel or some panels, but not the size of the page (e.g. make one panel 1/8˝ wider and another 1/8˝ narrower)? Or do you need to change the size of the brochure, which will change the size of one or more panels? Be specific.
I need to change the front panel, because it will have a white border on left side after folding.
I need to change the outside left panel to 3.625, and Center and right panels to equal – 3.6875.
then I need to reverse the inside panels.
Assuming that you are using a letter-sized sheet, I would start by creating a new document using that size, and include the bleed.
On the first page, put in a ruler guide at 3.625. You can specify the exact position in the Control Panel.
And another one at 7.3125 (3.625 + 3.6875).
First page should look like this:
Navigate to the second page.
Add a ruler guide at 3.6875, and a second guide at 7.375 (3.6875 + 3.6875), and it will look like this:
You say that the layout is already built, so you could copy and paste everything into this new document.
An alternative method, taking Willi's approach, would be to create a document with a 3-page master page. I would start by making the pages the size of the largest panel:
Navigate to the master page and in the Pages panel choose Master Options.
Change the pages to 3.
Choose Insert Pages from the Pages panel and insert 2 new pages.
Drag the master page icon in the Pages panel down into the document page area. Do this twice.
Delete the first page.
The Pages panel will look like this:
Select the Page tool and click on the first page.
In the Options bar, change the size to 3.625
With the Page tool, press and drag the first page to the right to close up the gap.
Repeat the same technique on page 6.
This is perfect. The way the Adobe tutorial explains it. You create the 2 pages, with 3 columns and gutters. This is much different. I wish Adobe tutorial video would explain this way. Thank you so very much!
Glad you found this helpful. If it solves the issue, go ahead and mark as Correct so that others will know.
