What is a folding rule?

Folding rules (aka zigzag or jointed rules) are those made up of two or more smaller rules that are joined together with hinges. They are easily collapsible and can be easily carried in any tool bag without taking up space. Also, since they can be manipulated into different angles or stretched into various lengths, they are a wonderful tool for projects that require you to work around corners or measure long distances.

What is the ideal length of a folding rule?

Folding rules come in many sizes, but the standard between 6 and 8 feet. When folded up, it can shrink down to a compact 6”.

What are the uses of a folding rule?

The primary purpose for any measuring device is to determine the length from one point to another, and folding rules are great for both small spaces and long distances. However, since folding rules can be manipulated into different angles, they have various other uses within the world of carpentry and construction.

Folding rules are also incredibly useful when trying to determine angles within a project for larger buildings/structures, especially in hard-to-reach spots. Additionally, if you’re tackling a large project, you can line up sections of the ruler with the angles in question, and those angles can then be measured with a protractor.

If your folding rule has more than two rule strips, they can be folded into the shape of the number ‘4’. This allows you to draw parallel lines using a straight edge.

How do folding rules compare to tape measure?

Anyone who does any sort of construction process has a tape measure. While they’re certainly a great tool to have, folding rules can provide plenty of benefits in their own right. Tape measures can be bent to measure within an angle, but they can also be a bit clumsy in those situations. Additionally, it’s harder to create parallel lines with a tape measure, as they are more susceptible to error.
