Photoshop size for a branding mockup
 

I am designing a single page mockup for a skincare brand and I was wondering what size would be best for the typical long page setup. Could someone also please advice the advantage of working with pixels as opposed to millimetres when setting up a page in photoshop..thanks!

It depends on what your looking at to see the page.

this may help.

Online calculator: Digital image size in pixels and photo print size
