Define 'typical'.  An image I have here that is just few line drawings
has these stats:
			TIFF		TIFF		TIFF
	   SIZE		NO CODING	PACKBITS	LZW
figure	2271 x 2540	721,702		60,980		24,290
	x 1 bit

That seems to be close to your guesstimate when LZW is used inside
the TIFF file.  But there really isn't much info in this drawing.
