I think it's also worth noting that Brachiosaurus can reach pretty good sizes as well.
The holotype FMNH P 25107 is about 23.8 meters TL and 45.4 tonnes going by this GDI (link) by SpinoInWonderland, when applying a density of 0.9 overall (following Larramendi and Molina 2020) as well as 5% extra meat to the dorsal view, which seems slightly shrinkwrapped.
And it's not the biggest specimen - USNM 21903 would be larger going by this chart (link) by Bricksmashtv. I measured it as about 13.88 percent larger than the holotype.
So based on an isometric scaling (45.4 x 1.1388^3) as well as neck allometry applied following Parrish and Taylor 2006, that would be about 30.8 meters and 69.5 tonnes. That's about as large as Argentinosaurus, who is in the region of 65-75 tonnes.
