Self-marking tape measures allows the user have a graphite tip, allowing for accurate markings. Surveying requires the measuring of large distances and require an increased need for accuracy. Due to this, measuring tapes used for surveying may be made out of invar because of its low rate of thermal expansion.
To measure the diameter of a tree, the diameter tape (diameter side facing user) is wrapped around the tree, in the plane perpendicular to the axis of the trunk at 4.5 feet (1.4 m) above ground (or 4.27 feet (1.30 m), depending on the location) . Where the number "0" aligns with the rest of the tape, the diameter can be read directly from the ...
A variety of rulers A carpenter's rule Retractable flexible rule or tape measure A closeup of a steel ruler A ruler in combination with a letter scale. A ruler, sometimes called a rule, scale or a line gauge or metre/meter stick, is an instrument used to make length measurements, whereby a length is read from a series of markings called "rules" along an edge of the device.

A ruler with two linear scales: the metric and imperial.It includes shorter minor graduations and longer major graduations. A graduation is a marking used to indicate points on a visual scale, which can be present on a container, a measuring device, or the axes of a line plot, usually one of many along a line or curve, each in the form of short line segments perpendicular to the line or curve.
Labelled diagram of the protractor head. The protractor head can be used for: Measuring and checking angles between surfaces, edges, and markings. Marking angles from an edge; Directly transferring angles, like a bevel gauge (sliding T gauge), to minimise measurement errors and inaccuracies.

The metre-stick is usually employed for work on a medium scale; larger than desktop work on paper, yet smaller than large-scale infrastructure work, where tape measures or longer measuring rods are used. Typical applications of metre-sticks are for building furniture, vehicles and houses. Modern carpenters' metre-sticks are usually made to be ...
