I was just working out the size a photo has to be for Facebook’s Timeline. So here is what I have worked out and I tested the image on my own Timeline and it fits perfect The size you need is 850 pixels by 350 pixels. It’s best to resize and crop any images you want to the exact size before uploading so you get it looking just the way you want. Shortly everyone will have Timeline turned on by default but you can request it’s turned on today by visiting http://www.facebook.com/about/timeline.
