Images too big in order email / logo too small

Hey all,
Can’t for the life of me figure this one out.

In the order confirmation email that goes to customers and to the admin - the logo is tiny and I can’t find a way to increase the size?

Also, the product images are massive and look ridiculous, I can’t find a way to reduce the size? This is also the case in the editor order panel when fulfilling orders.

Have tested multiple image types and files and same result - the image is just presented in the email in its original size there are no constraints placed on it.

As for the logo… tested multiple images also. Same size, tiny.

Help please?
