Serving charts aside, how many people would YOU say an 11 x 15 would serve?
It's 2 layers of cake with one layer of filling.
Thank you.
It depends how big your serving are. If it's just so everone gets a slice (ie 1" x 2") approx 75. If it's being served as a desert 2" x 2" portion is the minimum I would do - so more like 35 portions.
These are the two sizes I figure as a cake slice. These cover single and double layer cakes.
2"x2"x2"
1"x2"x4"
With these dimensions you should be able to figure out how many all of your pans serve.

Hope this isn't an ignorant follow-up question.........If you are figuring for a round cake, would you slice off the rounded portions (figuratively speaking) and calculate from there?
Sheet cakes are easy for me to figure out but I get in trouble when I think too hard about other sizes/shapes! 
I think in terms of a box mix or other single cake recipe.....it yields 24 cupcakes, a 2-layer 8" or 9" round, or a single layer 9"x13". So it seems to me that the round or 1/4 sheet should yield 24 servings....like the cupcakes. The 9"x13" does yield 24 2"x2"x2" slices. But I just can't see getting 24 wedges out of an 8" or 9" 2-layer round!! 
Am I just a piglet?

I usually knock of 10% for round or shaped cakes as a rough guide. ie 45 portions for square or 45 minus 4.5 portions for round - approx 40 portions.

No question is ignorant or stupid, we don't know until we ask.
I usually figure servings wedding cake style by moving in 2" from the outside of the cake then every 1" for 4" thick cakes. But I tend to look at stuff through trig/geometry and just in general mathmatically no matter what it is. Then you can just cut really thin wedges or cut wedding cake style.
But Bouncyboing percentage is a good one to go off of, and a little quicker to figure out
