Printable tools

Measuring tools drawn at true physical size. Each one carries a 100 mm reference bar and a scale field, because a print dialog set to “fit to page” will quietly shrink the sheet and nothing on screen can tell.

• Printable RulerA dual-scale ruler at true size: inches to sixteenths on one edge, centimeters to the millimeter on the other, and a square to check the print came out true.
• Printable ProtractorA 6-inch 180° protractor at true size, marked every degree, with inner and outer scales so it reads from either side and a baseline for setting the vertex.
• Printable Roof Pitch GaugeA card showing every roof pitch from 1/12 to 12/12 with its angle in degrees. Hold it against a rafter and read the pitch off directly, with no arithmetic.
