Not all rulers are created equal. Some are rigid, some are retractable tapes, some are in metric, some are in imperial. There is also a special kind of ruler used for converting the measurements on a scaled-down drawing or map: the architect scale ruler.
Here is the basic makeup of architect scale rulers:
- They come in a variety of scales
- Retractable tapes offer 2 different scales- one on each side of the tape
- Bevel & triangular architect scale rulers offer 4-6 different scales
- There are a variety of sizes- some can even fit in your pocket!
No matter what drawing you are measuring, there is a special architect scale ruler to help you out.
