About the pencil

A wood-cased pencil is a graphite core glued inside a wooden barrel, usually hexagonal or round in cross-section. US pencil maker Musgrave lists its standard hex and round pencils at 7.5 in (190 mm) long and about 7 mm across. Pencils get shorter with every sharpening, so this is the length of a new one.

  • Musgrave's carpenter pencils are shorter than a standard pencil at 7 in (178 mm), and its golf pencils are 3.0 in (76.2 mm) long. [1]
  • Ticonderoga describes its standard #2 pencil as having a 9/32-inch diameter. [2]

How many fit?

  • ≈ 8.8 × Pencil · length (new) lined up end to end match the Human · height
  • ≈ 3.8 × AA battery · overall height lined up end to end match the Pencil · length (new)

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

How it compares

  • 3.8× A pencil is about 3.8 times as long as an AA battery is tall. See side by side
  • 2.2× A pencil is about 2.2 times as long as a credit card is wide. See side by side
  • 1.2× A pencil is about 1.2 times as long as a US dollar bill. See side by side
  • 1/3.6 A soccer ball is about 3.6 times as around as a pencil is long. See side by side
  • 1/1.6 A sheet of A4 paper is about 1.6 times as tall as a pencil is long. See side by side
  • 1/8.8 An average adult is about 8.8 times as tall as a pencil is long. See side by side

Factors compare the length (new) of a pencil with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • Dixon Ticonderoga's product pages and 2022 catalog list the standard pencil's length only as 'Standard' with no number, so the length comes from another US maker, Musgrave Pencil Company.
  • No manufacturer source for the weight of a pencil was found, so mass is left out.
