This is a good set, great for a new cook or as a house-warming gift, or just to fill out a cook's colletion of pans.  The two sizes -- *LARGE* and large -- allow for a number of possibilities.  The largest pan is definitely big enough for a 20+-pound turkey.  It's really huge!  The smaller of the two pans is 10.5"x15" (larger than the standard 9x13 baking pan), and could easily handle two chickens or a large pan of lasagne.
