How big was your puppy at 12 weeks?

[Kaitee and Orwell]

I don't know if anyone else has kept a log of their doodle's growth rate, but I've been weighing him every week and yesterday I started measuring him. As of now (11 weeks) he is 18 lbs (probably more like 19 because he did get sick on an earthworm the night before) and 14 inches at the shoulder. 

The height is kind of scary because next Friday is his 12 week birthday. I found a general doodle growth chart which said that I can basically expect him to double in height. Even right now that would put him at 28 inches full grown. He is a big boy (I believe he was the biggest in the litter). I was wondering if anyone had a labradoodle of comparable size at this age? 

Though, I have to admit, I'm kind of excited at the prospect of having a 28-30 inch dog. I've always preferred the bigger dogs... I just did not anticipate it possibly happening with this guy. I told my parents I would stay away from the really big dog breeds for the time being until I moved out. He's thin like a poodle would be... but I'm starting to think he'll probably end up the size of a male greyhound (weight and height). I'd say his mom was about 24-25 inches at the shoulder. Not sure about dad... he was studded out to the owner of the mother. I just know that he was cream and no cream puppies were had (all black, with a few having a grey mask, but not to the extent of Orwell's).

What would your guys' analysis be?

Update:

Orwell is twelve weeks old today. He is 16.25 inches tall at the withers and 20.5 lbs with vacated bowels. He's going to be my big boy. (:

Myla was 20 pounds at 12 weeks and 30 pounds at 16 weeks.  She is now 2 1/2 years old and has weighed 63 pounds since she was one year old.  It seems that the rule of doubling their weight at 16 weeks with a variance of 5 pounds either way holds true of most F1 standard doodles.
