Well here's the ref sheet for my Dragon Argent. A silver dragon along the lines of those found in D&D. Her vital stats are as follows
Height: 9' 4” (2.8 meters)
Weight: Slightly rounded but not quite pudgy (Oh you wanted a number? That's rude.)
Wingspan: 19' (5.8 meters)
Tail length: 8' (2.4 meters)
