Yeah, there are methods of getting to a useful "it's about this big" estimate.

The real pain is turning estimates into deadlines. "About this big" doesn't equate to "it'll be finished on Thursday".

It should not be express as size then. It should be expressed in dice!

haha, love it. "Difficulty estimate: 15. Roll a d20 every day to see if it's completed, with a +1 modifier per day"
