The width of a ruler is about how wide? Choose the correct answer below: 4 m 4 mm 4 cm

Most standard rulers are typically about 4 cm wide, making them convenient to handle while measuring lengths. This width is practical for stability when laying the ruler flat on a surface and ensuring precise measurements without slipping. Interestingly, rulers can come in different styles and widths depending on their purpose. For instance, a carpenter's square might be wider for better support, while a flexible measuring tape is much narrower and can bend around curves! So, whether you're an artist or a builder, there's a ruler out there designed just for you!
