The diameter of a standard No. 2 pencil is typically about 7 millimeters (0.28 inches). This measurement refers to the outer diameter of the wooden casing. The graphite core inside is usually much smaller in diameter, around 2 millimeters.
The number of the pencil is based on the type of carbon lead used inside. The thicker the carbon lead gets the higher the number of the pencil becomes. If you notice a mechanical pencil is 0.9mm in diameter so it would be called a #0.9 pencil. A #2 pencil's lead is 2mm in diameter. So Why would we call a pencil a #3 pencil? Because it's lead is 3mm in diameter.
The perimeter of a pencil, typically cylindrical in shape, can be calculated by determining the circumference of its circular cross-section. The formula for the circumference is (C = 2\pi r), where (r) is the radius of the pencil. If you know the diameter instead, you can use (C = \pi d), where (d) is the diameter. Since pencils vary in size, the specific perimeter will depend on the dimensions of the pencil in question.
Typical Typically-sized pencil under a ruler. A standard, hexagonal, "#2 pencil" is cut to a hexagonal height of 1⁄4-inch (6 mm), but the outer diameter is slightly larger (about 9⁄32-inch (7 mm)).[
A standard number 2 pencil typically measures 7.5 inches in length when unsharpened. The diameter of the pencil is generally around 0.3 inches. This size is commonly used for standardized tests and general writing purposes.
An ordinary pencil is one example.
The standard diameter of a pencil is about 0.3 inches or 7.6 millimeters.

The diameter of normal size pencil lead is about 0.7 millimeters.

A standard pencil is typically about 7 millimeters in diameter, which is roughly 0.28 inches.
A typical pencil is about 7 inches long and 0.25 inches in diameter.

A 7mm pencil lead is thicker than a 5mm pencil lead. The diameter of the lead determines its thickness, so the lead with a larger diameter will be thicker.
