Gargantuan? Creature size categories?

Hello people,

I can't for the life of me find the number of squares gargantuan creatures occupy. The compendium seems to be of no help either. Is it only 4 by 4 (1 step up from huge)?

Collossal as a size category between gargantuan and huge has been removed right?

Edit: Nevermind, I thought of one very odd way of finding my information: Google

Apparently gargantuan is 4x4 or larger.

Colossal was the step up from gargantuan in 3rd edition

3.0 colossal was typically 8"x8" if the creature was bipedal or 'tall', 8"x16" if the creature was quadrupedal or 'long'.

3.5 changed the default colossal base to 6"x6".
