Facebook profile & fan-page
Although a Facebook profile and a fan-page are two completely different things, most of the image sizes are the same. There are five image sizes in the both Facebook timelines, being the cover photo, the profile image, the custom tab/app thumbnails, the shared photos and the highlighted photos.
Cover image: The cover image is really important in the fan-page since this is the place to catch the reader’s attention. The fan-page timeline cover image used to be a little bit bigger as the one from the profile timeline but recently this was changed to: 851 x 315 pixels. You can use an image from your photo album but it would be better to upload a new custom made timeline cover photo to make good use of this space, especially in the fan-pages. In case of a fan-page there are some rules and cover images should not include: Price or purchase information such as 50% off, contact information such as web or email addresses, references to likes or shares or any other Facebook features and call to action such as “get it now”.
