I am fairly new to doing quilts and have seen many patterns out there now for charmpacks but never knew how many it would take
Heres what I found based on the 5x5 charmpacks...
Crib/lap 42x50 need 120
twin 69x90 need 320
full 84x90 need 380
queen 90x96 need 440
king 104x96 need 528
These figures are based on using the squares only - you could cut down the number of squares by using borders etc
Hope this helps..I found it very helpful Thanks for letting me share!! cheryl
