What decides the size of the logo displayed on the Spotlight?

[Kyouma 48]

I thought the size would be determined by the resolution of the logo, but that seems not to be the case.

I have 4 examples. 

Link Click 800x310

Spoiler

Bleach 800x310

Spoiler

Clevatess 2400x772

Spoiler

Jaadugar 1200x637

Even though Clevatess and Jaadugar have a higher resolution, the other 2 appear a lot bigger. Why is that?

I'm currently in the process of changing the art for all my shows, but I'm unsure what resolution I should pick to have the correct size. 

Because while Clevatess has a good size, Link Click and Bleach are too big and Jaadugar is a bit small for my liking, even though the resolution would suggest it to be different. 

Any insights would be appreciated.

Don't know if this is specific to Apple TV or a general one.

It's constrained to a maximum height and width.  So a very wide logo that exceeds the maximum width will not be as tall as a narrower logo which will fill it's maximum allowed height.

The logo will always get scaled up or down to fit either the maximum width or height so changing the resolution won't do anything for you.

Ok, that explains it. But is there anyway I can adjust it? I'd like to get Link Click and Bleach a bit smaller and Jaadugar a bit bigger. Is there a way for me to achieve this?

Could you share the max width and height?
