The Indominus is bigger in not only height and length, but also weight, more capable arms, more intelligent, and can take more hits. Absolutely. Size alone does not determine the outcome a fight, unless one combatant dwarfs the other. A T.rex-size-raptor could've taken down Rexy at the end of the original, but given how small the raptors were, Rexy won easily.

It isn't as cut-and-dry in this case though. InGen's Spinosaurus and Indominus Rex could both grow to approx. 50 feet in length, so size isn't a factor. Indominus is smarter than Spinosaurus, has tougher armor, is more tolerant to pain, has a more powerful bite and more usful forelimbs.
