Measuring is one of the most important steps in completing any project, as the old saying suggests: "Measure twice, cut once." The following tools that can make the task easier: Standard tape measures come in different lengths and may be used to measure a variety of things (figure A). The carpenter's rule folds in 6" increments (figure B), with a sliding brass rule on top for measuring inside drawers and other tight spaces (figure C). Measuring tape is self-adhesive so it can be stuck to the surface to be measured or act as an affixed ruler on a work surface (figure D). The try square is used to test squares and right angles to make sure they're a perfect 90 degrees (figure E). The combination square is used to measure right angles and 45-degree angles (figure F). It can also be used as a ruler. The measuring wheel records measurements from point to point--vertically, horizontally or around corners (figure G). Most measuring wheels measure 1' at a time and display the measurement on a meter (figure H). They're useful for laying foundations and measuring long distances.
