Nice sizes, though I'm surprised you excluded Titanoceratops and Dacentrurus. Dacentrurus had a 1.5m wide pelvis, as displayed here [img]https://lh5.googleusercontent.com/-rwbhNPFX34o/UjMnEbNQaTI/AAAAAAAAAJ4/QrguYmXjFFc/s640/blogger-image--1787717113.jpg[/img] roughly twice the size of an average S. armatus pelvis, making Dacentrurus 10m.

Titanoceratops is just 6,5 meters long. Dude, I included Dacentrurus: is the laregst of the blinded dinosaurs.

Oh, sorry. I didn't even notice it. And I thought Titanoceratops had a 2.5m skull?

Yes, it has a freak 2.5 meters long skull, but that's because, as reconstructed 55% of that 2.65m is all frill, in fact, the description recognizes that large specimens of Triceratops were larger, like LACM 150076, which has a femur 117cm long and is 4% thicker than the 102cm long femur of the Titanoceratops holotype, and while not mentioned in the paper, there's even larger specimens of Triceratops, CM 1618 has a femur 127cm long and AMNH 971 has a humerus 83cm long, which if it has the same humerus/femur ratio as CM 1618 and USNM 4842, will have a femur around 1.4m long. If Titanoceratops was 9m long then how big are these? 12-13m? Longrich (2010) has a skeletal, after correcting the wrongly scaled scalebar it shows Titanoceratops to be between 6-7m long.

I'm surprised you left out Ankylosaurus and Charonosaurus. Ankylosaurus was probably about 6-8 meters long and weighed around 4-5 tons, maybe more. Charonosaurus is often estimated to be around 10-12 meters long, which would rival, say, Saurolphus. Just a thought, not a huge deal though ;)

Ankylosaurus is "just" 6-7 meters long (with 4 tonnes of body mass). Charonosaurus is likely about 10 meters long, about the same size of his relative Parasaurolophus.

They were just some suggestions. Like I said, no big deal really.
