About the Barleycorn

Facts & Uses

  • Shoe sizing foundation: UK/US shoe sizes increment by 1/3 inch (one barleycorn) between consecutive sizes.
  • Historical standardization: King Edward II (1324) defined inch as three barleycorns placed end-to-end.
  • Modern applications: shoe industry still uses barleycorn increments; size 8 to size 9 = one barleycorn difference.
  • Traditional crafts: historical reenactment, traditional shoemaking, and period construction projects.

Curiosities

  • Agricultural origin: literally the length of a grain of barley; practical measurement for small distances.
  • Shoe size paradox: children's and adult's sizes use different starting points but same barleycorn increments.
  • International variations: European shoe sizing uses different systems, creating conversion challenges.
  • Legal history: barleycorn measurements appear in medieval English law and trade regulations.

About the Inch

Facts & Uses

  • Dominant in US construction, plumbing (pipe diameters), electronics (screen sizes), and hardware (screws, bolts).
  • Screen technology: TVs, monitors, phones measured diagonally in inches; DPI (dots per inch) defines display resolution.
  • Fractional system in construction: 1/2", 1/4", 1/8", 1/16" for precise fitting; decimal inches in engineering and machining.
  • Paper sizes: US letter 8.5 × 11 inches, legal 8.5 × 14 inches; tire dimensions use inches for rim diameter.

Curiosities

  • Historical origin: three barleycorns placed end-to-end; width of adult thumb at knuckle.
  • Exactly 25.4 mm since 1959 international agreement, ending slight variations between countries.
  • Symbol "" (double prime) distinguishes from feet (') in architectural and engineering drawings.
  • Smartphone screens paradox: measured diagonally in inches despite metric internal components and manufacturing.
