Terrain sizes (Titan arm terrain)

[maverike_prime]

So I'm contemplating building the blaster arm of a titan as a terrain piece, basically copying the gimmick from Dawn of War: Dark Crusade where the Imperial guard had control of the gattling blaster of an Emperor titan and could use it as a "burning" line defense.

And I was chatting a friend about it and she and I have come to a bit of an impasse as to how big to make it. I'm figuring on it being 14-18" long and thinking that any bigger and it will simply be too large a terrain piece while she's emphatic that if it's a titan's arm it would have to be at least 24" long other wise it would simply be too small.

 

What are your thoughts on this particular argument?

What class of titan are we talking about? The one in the picture is an Imperator, as you stated, but is that the class of titan you want? If so, '24 inches at least' is fine. Those things are almost as tall as a human IRL. If you deem that too large to be practical, just use a smaller class of titan, such as a reaver.

According to the scale diagram from the Imperator's Apocalypse datasheet, it stands approximately 39" tall on tabletop, equivalent to 55.5 meters (166ft) in real life. Dies Irae,[1] the famous Chaos Imperator Titan that laid siege to the Imperial Palace, was stated as being 43m (130ft) tall, though it is by no means clear that Dies Irae had cathedral spires, serving as it was during the time of the Imperial Truth.[Needs Citation]

 

I don't have either Apocalypse or Epic: Armageddon so I don't know if there is more information on that, but I'd look for a profile picture of an Emperor Titan size it up to the above mentioned Datasheet (couldn't find it on the site so here's a direct link thanks to google) to measure and convert it's dimensions.
