In theory, 220. However, If you find the exact center of the room, and work from there out (since you line up your tile from center, not from an edge), then you may find that you need a little extra at the edges, especially if you are tiling a pattern into the floor.
To find the exact center of your room, and to mark your starting grid lines, measure each wall at the bottom from one corner to the next, and mark the exact halfway point. If you have a closet or other feature protruding into the room from the corner, measure as if it weren't there. Then mark two lines on the floor, one running the length of the room, and one running the width of the room. In theory, if you have measured your room accurately, then these two lines will be perfectly 90 degrees perpendicular to each other. This is where you start laying your tile. If these lines aren't 90 degrees, then you may have measured incorrectly.
