Yes? They're at least 50 meters tall, since that's how tall Wall Maria is and possibly all the other walls. I believe the implied theory, at least by the anime, is that they're taller than that. If I'm remembering the disclosable information images shown between commercial breaks correctly, there was a story about a man within Wall rose(?) who decided to try and tunnel his way into Wall Sina(?).(What I know for sure is that he was trying to tunnel under a wall into the next area) And after months(?) of digging, he never found a bottom to the walls. One day he told a friend of his what he was doing while they were at a bar. The friend never saw him again.

There's also the general belief by fans, I'm not sure if it was mentioned in the manga, that Betolt's Titan is like the Wall Titans. So if Bertolt's Titan is taller than 50 meters, then maybe the Wall Titans are also taller than 50 meters.

Hopefully they manage to talk more about Wall Titans in the future, because they really haven't said much about them.
