The quilts I make now are about 45 x 60 and they are throws for the sofa. I made myself a few in different seasonal colors - I have a fall one, a winter one and a Christmas one at this point. I may make spring and summer ones. I think they change the feel of my den. The rest I give away.
I like to quilt a piece of this size. It's not too bulky and it goes quickly. Making bed sized ones are not fun to me and I'm in it for the fun!
