mine is 145cm x 200cm, weighs roughly 8-9kgs. Mine is thinner than a normal blanket (well my normal non-weighted blanket that i also use).
Covers me like a normal blanket (feet covered, blanket ends at my chin),
Keep in mind that most blankets are smaller than mine. Also: the bigger it is the lighter it will feel because the weight is spread evenly in the blanket, so if you want a large one you're gonna want it to be heavier one, too.
Mine is over 10% of my body weight but since the weight of the blanket is evenly spread out and the blanket is so big, its okay.
Cool thing about weighted blankets: they take a long time to get warm but once they do they stay warm for a long time too! I typically have my normal blanket on top of my weighted blanket to get warm and then remove the normal blanket.
