A ruler is a device for measuring length. It is often 12 to 18 inches (30 to 46 cm) long, and traditionally made of wood (more recently it may be of metal or plastic). A long ruler is called a yardstick. A ruler is sterotypically used as a spanking implement in school settings, either on the palms, knuckles, thighs, or on the bottom. As such it serves as a short, narrow ferule or paddle. A blackboard ruler is a bigger type of ruler. Some types of blackboard rulers have a handle in the middle.
A punishment with a ruler is also called a rulering.
