Word default settings

Question

I changed my page set up settings in order to accommodate a book I'm publishing. And I cannot reset them to the default.

Answer 1

If you did change the default Page Setup specs you should be able to reset them as Stefan advised but changing the specs for any given document doesn't have any effect on the default.. Without specific details it's difficult to provide anything other than an educated guess.

Another possibility is that you've inadvertently hidden what Microsoft calls White Space [Headers & Footers]. In that case please see this existing explanation: White Space

Answer 2

On the main menu bar, click Format and then click Document. This will give you access to settings for margins, paper format etc. Make the desired changes, which will be applied to the current document. Use the Default button if you want to copy the settings to the attached template.
