I think you don't need some of the length if you are using a footboard and don't need the fall at the foot.
Width
60"+13"+13"+9.5"+9.5"+3"(Shrink)=108" Wide looks right
Length
80"+13"+9.5"+12"(Pillow Tuck)+3"(Shrink)=117.5 take away the 13 and 9.5 since the footboard would interfere, and maybe add another 3 or 4" to your shrinkage allowance instead, so you have a little to tuck at the bottom.
