Ruler

A boy is beaten with what appears to be a ruler.

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.

Use as spanking implement[edit]

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.

Mainstream films[edit]

In the period piece drama Little Women (1949) set in the 19th century, a misbehaving schoolgirl holds her hand out for a ruler smack. This scene can be watched on YouTube.

Peeples (2013) is a contemporary romantic comedy featuring an unusually energetic and lighthearted scene of kinky consensual spanking. Grace (Kerry Washington), seduces her fiance Wade (Craig Robinson) and initiates the spanking by taunting him while dressed in her old schoolgirl uniform. This roleplay includes holding a wooden ruler in her teeth. Pretending to be a principal, Wade pulls her over his knee and vigorously spanks her about a dozen times with the ruler as Grace squeals with sexual excitement and kicks her legs.
