Facebook event Image Size
Do not hesitate to make them bigger (but not smaller, for ideal results). Both myself as well as Facebook frequently suggest a 1200 pixel size. And also the event cover photo? It keeps changing!

2019 Update: Facebook Event Cover Photo Size
Checked and verified January 4, 2019: The recommended Facebook event cover picture dimension is 1200 x 628, same as a link share. This is a 1.91:1 ratio.
I highly recommend you make use of a bigger picture! I examined the display screen dimension on iPhone, iPad as well as desktop computer, in both the event and also the linked Team. Four of these 6 display at higher than 1200 pixels broad on retina screen. Friends, you don't want Facebook stretching your gorgeous event Cover Photo.
I suggest 1920 pixels large. You can go with the 1.91:1 percentage as well as make it 1005 pixels high. Or, simply use a typical 16:9 shape, as well as know that there will be a bit of chopping leading as well as lower (see layout). The terrific information is, the cropping is practically the same in all 6 areas. I took screenshots so you can contrast. On desktop computer there is a small chopping on the sides.
The Facebook event image size on desktop displays at 1246 x 652 pixels.
The Facebook event image size on iPad displays at 1288 x 674 pixels.
The Facebook event image size on iPhone displays at 1242 x 650 pixels.
ALL of these are 1:1.911 facet ratio. This means that the width is 1.911 times the elevation.
