Here you can see how big the Samsung Galaxy S8 Plus will be compared to other phones

Here are some images that compares the coming Samsung Galaxy S8 and Samsung Galaxy S8+ with other phones like the iPhone 7 plus, iPhone 7, Galaxy Note 7, Galaxy S7 and more when it comes to size.

You can clearly see (as I've said before) that the Samsung Galaxy S8 Plus won't be bigger than the iPhone 7 plus, even with a larger 6.2-inch display. That's awesome. All this thanks to the new almost bezel-less design. Kinda neat to also see that the Galaxy S8 will be smaller than the iPhone 7 even if it will have a 5.8-inch display :)
