How To Change Page Size and Ratio in Pages

Difficulty - Easy

Step 1 - Open "Document Settings"

Select the name of your document in the top left of your screen.

Step 2 - Select "Document Setup"

Under "Document Settings", select Document Options and then Document Setup.

Step 3 - Select Document Size

Select the appropriate size for your document.

If none apply to you, select Custom Size.

Step 4 - Input Custom Page Dimensions

Input the size you would like the document to be.

If the second number changes right after you change the first one, the aspect ratio is locked. To bypass this, and change the numbers independently, select the lock to unlock it.
