queen for the kids and king for us. We don't use quilts to snuggle in. I make the kids use blankets a nd keep them folded in the closet.

I've made some baby quilts approx 40x60 up to twin XL but I've only made 8 quilt so far and don't want to make anything larger because it was hard enough quilting that twin XL on my home machine and I don't want to send them to someone for quilting.

One day I will have my own longarm hehe :)

I spent yrs making K size for our bed,Qsize for DDs.Now I'm doing throws a lot & some miniatures.Just sent last K size to LA quilter.No room for more K size quilts,fabric is more $$$ & tired of making same block quilts.But that's just me.

I decide based on who its for and how it will be used. On average - 65"x85" for the couch...I like to wrap myself right up. My first couch throw is 50x70, and its ok to use (I'm under it right now!), cozy and all, but I just don't find it big enough.

Usually queen size, unless I get carried away, then king size. That way, it doesn't matter who they are for, usually they will fit any ones' bed.

Thank you all who responded. I was just curious about how you judged the size quilt you made for every day use. I know when I was working in fabrics and ppl would ask about fleece blankets, I always told them to go by how tall the person was they were making it for.
When I made rag lap quilts for my DH and my dad, I made them different as my DH is over 6 foot. I also added a fleece pocket on the back so they could stick their feet in to be extra warm.
Thanks again for all the responses. It was just a curiosity thing on my part. :)
