I like to play around a lot when it comes to making timeline pictures for Facebook. Then a client wants that picture to buy. I should explain the aspect ratio is around 3:8 ratio in the timeline of Facebook. So it is hard to get the same look in an 8x10, which is a 4:5 aspect ratio. I always try to accommodate the client and I can get a 5x7 or a 4x6 and sometimes an 8x10, yet it may be just a smidgen different. Same pic and text and texture, yet maybe different. The best aspect ratio that is similar in my opinion for changing to more of a standard portrait size is the 5:10 ratio. Yet if the client wants that long pano appearance like on the Facebook timeline, they can have it. The sizes that could be done are 3x8, 6x16, 7.5x20. Here is my latest timeline composite.
