Isn't it taller, but less wide, and thinner? There total surface area is probably bigger (height increased about 1cm whereas width decreased about 3mm), but I think it will feel smaller in your hand. When holding a phone, it's generally the width & thickness that makes it feel big. Both of those dimensions decreased.
If you're talking about thumb-stretching to reach the top of the screen, though, that might get a bit more difficult.
From what I see, the new one is 72.6 mm wide, and the old one is 69.2 mm. I.e. it's wider (which can make it annoying, if you can't comfortably hold it in your palm or in your front pocket).
