is for Four Foot. The rings at the ends of a curling sheet measure twelve feet, eight feet, and four feet in diameter. At the center of the four foot ring is the button. Because scoring in curling depends on having rocks closest to the button, the four foot ring is strategically important. This is demonstrated nowhere more emphatically than in a skins game format, where both teams spend three quarters of each end jockeying for control of that prime piece of frozen real estate. Common curling wisdom has it that any skip worth his salt should be able to draw the four foot at will.
Other important Fs in curling are the Free Guard Zone, and the Four Rock rule, both of which serve to inflate the importance of the four foot ring.
