Measuring your bed to have a comforter made is actually very easy.  Comforters are more forgiving than anything else on your bed.  They don't have to come to exactly any point in their drop, or fit around any corner with precision.  Usually, it is enough if they overlap the beginning of the bed skirt by a few inches.

When measuring for your Comforter, first measure the width of your bed, out to the expected width for your bed size.
	Then, just measure down from that point to where you'd like your comforter to stop.  If you don't specify a drop for your comforter, we'll give you our standard drop, which is fifteen inches.  This is more than enough for most pillow top mattresses.
