Is Queen Mary 2 bigger than Titanic?

But Queen Mary 2 is bigger than Titanic, much bigger.

In fact, if she was in service today, Titanic would be classed as a small to mid-size ship, clocking in at a mere 46,329 gross register tons.

Compare this to the 149,215 gross tons of QM2, and you get a good idea as to how much bigger QM2 really is compared with Titanic, at least in terms of internal volume.
