While I agree almost all phones are to large, I don't know they are that bad.
I recently overheard a conversation where someone was amazed by a colleagues small phone and wanted to know what it was. "Wow, what is that phone its so small!" "uhh, it's just a pixel." "Aren't pixel's huge?" "Those are pixel XL, this is a normal pixel..."
The pixel 3 is 37% larger in volume than the iphone 5. It is only 15% larger than the iphone 7... gosh but I wish phones release normal+ xl + compact.
