Robin, hard to say without a picture of the whole layout. Based on the limited info, find door center, lay tile dead center, break right and left, see what size pieces you end up with against each wall. Next find door center, lay grout line at center mark, break right then left, see what size pieces you end up with along each wall. If there is one wall that is hidden, like under baseboard heat, you can use the long wall as a full tile----IF it is PERFECTLY square to the front door, compromise is most often the case, good luck GMOD.
