In the United States, and prior to metrication in Britain, Canada and Australia, architect's scales are marked as a ratio of x inches-to-the- foot (typically written as x″=1′-0″). Architect's scales may be flat, with 4 scales, or have asymmetric 3-lobed cross-section, with 6 or 12 scales. Scales were traditionally made of wood, but today they are usually made of rigid plastic or aluminum.
Classes include professionally produced videos taught by practicing craftspeople, and supplementary downloads like quizzes, blueprints, and other materials to help you master the skills.A triangular architect's scale, made of brassĪn architect's scale is a specialized ruler designed to facilitate the drafting and measuring of architectural drawings, such as floor plans and Multi-view orthographic projections.īecause the scale of such drawings are often smaller than life-size, an architect's scale features multiple units of length and proportional length increments.įor accuracy and longevity, the material used should be dimensionally stable and durable. MT Copeland offers video-based online classes that give you a foundation in construction fundamentals with real-world applications. If you want to draw a line to indicate a window that is 4.5 feet long, begin it at the halfway point of the smaller gradations and then continue out until you reach the “4” mark. These fractions of an inch allow you to measure fractions of a foot.
If you then want to measure out a 4-foot wall at a particular scale, simply begin your line at zero and draw it to the “4” mark on that scale.If your scale has 1/4 at one end of an edge and 1/8 at the other end, the row of numbers that starts with zero closer to the 1/4 are the numbers that correspond to that scale, with a 1/4 inch corresponding to one foot. On a triangular scale, you’ll most likely find two rows of numbers on each edge, one above the other. Find the corresponding scale on your ruler.If different scales have been used for different drawings on the same page, look for it underneath the specific drawing. If one scale has been used for an entire sheet of the plans, the scale will typically be found in the legend.

Learn everything you need to know about reading blueprints in MT Copeland’s online class, taught by professional builder and craftsman Jordan Smith. Understanding scales is only one of the many skills you need to read a property’s blueprints. This makes it quick and easy to draw different prints at different scales, as well as interpret different prints at different scales.” “We have a lot of different scales represented in this single ruler.

These are typically 12 inches long and you can find a remarkable variety to choose from: plastic scales, others of solid aluminum, and ones with color-coded grooves.
Some sets with multiple rules can include up to 16 scales. A triangular architect scale has a total of six edges, often with two different scales-say both 1 inch to 1 foot and a ½-inch to 1 foot-represented on the same edge.
