clockwise - Instagram, Twitter, Pinterest and Facebook posts
Select the page you want to resize by tapping the page thumbnail in the Documents panel. The Page size dialog which is part of the Page Properties panel appears on the right side.
In this example the selected page is a print document - you can see the Print category is ticked to indicate this.
Click on the Print category to display the various page size options.
You can see that our selected page is Portrait and also A4. Just select your new page size from one of the options.
Here we’ve got that A4 page resized to the US Letter size. All the page elements fit the new size.
The other categories are…
Print - as described above.
Presentation - standard and widescreen aspect ratios - for PowerPoint too.
Web - common webpage sizes of 1200px, 960px, 760px and 640px.
Social Media - Facebook, Twitter, Google+, Instagram, LinkedIn, Pinterest, YouTube, Tumblr.
Custom - enter you own page size.
There’s also the additional option All pages the same - select this if you want your changes to apply to all the pages in your document.
All the document templates have been marked up to deal with automatic page resize but there are a few things to bear in mind.
For best results change like for like and stick to the same category as the originating document - so print to print, presentation to presentation and so on. The same for landscape and portrait.
It’s a good idea to change the page size first and then replace the placeholder content with your own - so create all the sizes you want first using a template, save individually, then go back and add your content.
When designing for your own custom page sizes, always design for the smallest page size, it is easier to enlarge a format than to shrink it.
