39+ 1600 Vs 1920 For Facebook Photo Background. I tried it myself uploading 2048×2048 px of 2 same images with 72ppi vs 300ppi. Do you want to join facebook?
It was a bit of an adjustment to the larger screen and i do find myself getting close to the monitor to read text from time to time.
They display at 820 x 312 pixels on most computers and 640 x 360 pixels on facebook event covers have a different size from a regular page's cover photo. The optimal size for a facebook cover photo is 820 x 312 pixels. Facebook cover photos look like banners on top of your facebook timeline. A facebook cover photo is visible on your personal profile only, however it takes up a large portion of the page.
