Correct image size for Collection page header?

[BothHands]

If I understand correctly, the suggested image size for a Zazzle Store header is 2280 x 380 pixels. 

That seems too wide for a Collection page header (?) but I've found no specification for Collection page headers. 

Does anyone know for sure what image size is recommended for Zazzle Collection pages?  

Thanks,
Tom

I'm new at all this, so take what I say with a grain of salt:

I've been experimenting since asking the question above.
A file size of 2150 x 600 pixels is working well for me.

CLARIFICATION
For any who might read this thread in the future, I returned read for a second time the linked post furnished by PacifierCity above.  This time I saw the following, which is exactly what I needed.  Somehow failed to see it the first time...(duh):

Collection banners are 1140 x 315.

My own seat-of-the-pants 2150 x 600 works well, but 1140 x 315 for Collection banners is spot on.

Thanks again, @PacifierCity

WAIT! ⚠️

Do read that entire post by @ColsCreations that @PacifierCity linked to. I am like you and saw that the 1140 x 315 size was working, so have been making my banners that size, especially since when I created the larger size 2048 x 565 it told me to crop it. 

But ColsCreations explains why we need to make it larger so it will work on various devices. They also explain what parts of our Store Images will end up showing - so we can make it look the best it can.

Sad to say, I have to start over and here I thought I was nearly done making store banners. 😢

Now if only someone will tell me what dpi to use.
