Hot off the presses!
Google plus just today updated their cover photo sizes. Instead of the usual 940X180 which I and I am sure many others agreed, was way too small. But it seems Google plus have gone way over to the other side with new cover photo sizes that can go up to 2120pxX1192px. When expanded they should display in 16×9. There is a minimum size of 480X270 so I guess it provides a bit more flexibility. Don’t let the large size scare you, since there is a lot more you will be able to do with this new size.
Another change is the profile photo area which is no longer a square but a circle.
So what do you think?
