The Fascinating History of the Ruler Over Time

The ruler, this indispensable tool in geometry, has a rich and ancient history. It is used to draw straight lines and measure distances accurately. Here are some key stages of its evolution:

• Egyptian origins: Invented over 4,500 years ago, the first ruler was made of wood or bone, with simple graduations in inches and lines. The Egyptians used it to draw lines in the sand and measure distances during the construction of monuments.
• Evolution of materials: Over the centuries, the ruler has been perfected, moving from wood to metal, then to plastic, offering increased durability and accuracy.
• Modernization: In 1854, the Stanley Rule and Level Company revolutionized this tool by introducing the first metal ruler, even more precise and durable.

Today, rulers are available in various formats and materials, including digital versions like online rulers.
