What is a measurement of a pencil?

The standard measurement of a typical pencil is about 7.5 inches (19 cm) long and approximately 0.25 inches (0.64 cm) in diameter. Pencils usually have a hexagonal or round shape for grip and can vary slightly in size depending on the manufacturer. The lead inside, which is made of a mixture of graphite and clay, can also differ in thickness and hardness based on the pencil type.
