Whether for math class or the art room, almost every student can use a reliable ruler. We’ve gathered together the best for your back-to-school needs!
What to Consider When Purchasing a Ruler
A good ruler will have a few basic elements:
- Measurement: Most rulers will include both centimeters and inches, which is incredibly useful. The measurements should be clearly marked and easy to read.
- Straight Edge: Some rulers will offer fun lines or stencils, but at least one side must have a straight edge, preferably the edge with the measurements.
- Durable: A good ruler should not be easily broken or shattered, so look for ones made of wood, rubber, or thick plastic.
