Movie character height & weight reference here.

There have been several threads about the scale of movie figures. Maybe my comment here will be useful information, especially to those who did not attend the Botcon 07 dinner party. The goodie bag contained an uncut tech-spec sheet of all the movie Transformers and is pictured below. On the back is a short bio of each character.
The heights and weights of the characters are described as:
Megatron 35 feet / 5.7 metric tons
Blackout 33.5 feet / 2.9 metric tons
Starscream 31 feet / 2.6 metric tons
Barricade 16.3 feet / 2.16 metric tons
Frenzy 4.6 feet / 110 kilograms
Brawl and Bonecrusher were not included.
Optimus Prime 28 feet / 4.3 metric tons
Ironhide 22 feet / 2.4 metric tons
Ratchet 20.1 feet / 2.3 metric tons
Bumblebee 16.2 feet / 1.6 metric tons
Jazz 15.7 feet / 1.8 metric tons
You can see that Leader Megatron should be taller than Leader Prime. Megatron, Blackout, Starscream and Prime all fit rather closely and can reasonably be in leader size. A sense of proper scale could have been preserved if they would give or take an inch within this class.
If you base the scale around the Prime figure, Megatron should be bigger while Blackout and Starscream should be just a bit shorter than Megatron, but bigger than Prime.
Leader Brawl will most likely be too big (but I'll take it over the deluxe size!).
