Terms used to describe the game include:

The ice in the game may be ''fast (keen)'' or ''slow''. If the ice is keen, a rock will travel further with a given amount of weight (throwing force) on it. The speed of the ice is measured in seconds. One such measure, known as "hog-to-hog" time, is the speed of the stone and is the time in seconds the rock takes from the moment it crosses the near hog line until it crosses the far hog line. If this number is lower, the rock is moving faster, so again low numbers mean more speed. The ice in a match will be somewhat consistent and thus this measure of speed can also be used to measure how far down the ice the rock will travel. Once it is determined that a rock taking (for example) 13 seconds to go from hog line to hog line will stop on the tee line, the curler can know that if the hog-to-hog time is matched by a future stone, that stone will likely stop at approximately the same location. As an example, on keen ice, common times might be 16 seconds for guards, 14 seconds for draws, and 8 seconds for peel weight.

''The back line to hog line speed'' is used principally by sweepers to get an initial sense of the weight of a stone. As an example, on keen ice, common times might be 4.0 seconds for guards, 3.8 seconds for draws, 3.2 for normal hit weight, and 2.9 seconds for peel weight. Especially at the club level, this metric can be misleading, due to amateurs sometimes pushing stones on release, causing the stone to travel faster than the back-to-hog speed.
