The Curling Sheet

The ice playing surface is called a sheet and is 138 feet long by 15 feet wide. The main features of the sheet are the house (target), the hack (foothold), the hog line and the tee line.

The house is the scoring area consisting of three concentric rings 4, 8 and 12 feet in diameter.  The hack is the foothold where one delivers or throws the stone.  A player delivering a stone must release it before reaching the near hog line.  A stone must completely cross the far hog line to be in play.  The tee line crosses the house at its midpoint.  The spot where the tee line crosses the center of the house is called the button.

The ice surface is not smooth but has a textured surface called pebble, which is formed by sprinkling water droplets over the ice.  The pebbled surface allows the stone to glide with just the right amount of friction.
