The size of a tula will depend on the size of the clan, their mix of hunting/herding and agriculture, how active they're prepared to be in defending it, and what was negotiated with the powers of the land during the clan making rituals in the Resettlement period.
The Heortling clan generator
(http://www.glorantha.com/tools/clan_start.html) gives an average tula size
of around 240 hides.
A hide is itself somewhat variable, being an Old English measure of land based upon the area needed to support a small family and its dependents, usually between 60 and 120 acres. For Hero Wars purposes, a figure of 120 acres is assumed.
So an average tula is around 120 sq kilometres.
1 hide = 120 acres = 48.562 hectares = 0.486 sq kilometres = 0.187 square miles
Check out the Heortling Stead project, which is a now defunct, pre-wiki, Yahoo group that did some interesting work a few years back. Its web page has lots of links and some interesting detail on Swenstead, the pilot project.

(BTW, we once, without much success, debated the origin of the word 'tula'. In recent reading, I've come across the medieval Welsh word 'tuela', which means the warrior band or comitatus of a lord, and literally means 'family'. I'm wondering if 'tula' isn't a misremembering of this term.
