What type of rule do masons typically use for determining course spacing?

Masons typically use a folding rule for determining course spacing because it provides a perfect balance between length and portability. The folding rule can be easily carried in a pocket, making it convenient for quick measurements on a job site. Its articulated sections allow for flexibility in measuring both short and longer distances while remaining stable when fully extended.

The folding design also enables precise measurements when working in tight spaces or when slight adjustments are needed. Additionally, the printed markings on a folding rule are often clearer and more durable than those on other measuring devices, which helps ensure accuracy in course spacing—a crucial factor in masonry work.

While other measuring tools like steel rulers and measuring tapes have their uses, the folding rule’s combination of durability and ease of use makes it particularly well-suited for the specific needs of masonry. A wooden yardstick, though useful in some scenarios, is typically not as versatile as the folding rule for masonry tasks.
