HOW TO READ AN ARCHITECTURAL OR ENGINEERING SCALE


Architects and engineers use a scale to draw something very large or very small. You may need to scale something up for finer detail, or you may need to scale it down for a building or plan of an open location. A 12-inch scale will have six sides, which can convert different lengths into feet. The number on the edge will tell you the scale you’re using. But regardless of which side you need, there are two basic types of scales. An architectural scale is used to describe the interior or exterior of a building, while an engineering scale is used to describe a site or property. Be sure to look at what we have at Engineering Supply. We’re sure you’ll be able to find a scale that will meet your specific needs.

AN ESSENTIAL TOOL FOR ARCHITECTS AND DRAFTING PROFESSIONALS

Whether you need to draw something very large or very small, an architectural or engineering scale is an essential tool. An architectural scale is good for taking measurements off of a scaled paper drawing, and you can take a triangular scale with you because you can store it in a briefcase or carrying bag. Both scales are easy to read, so it’s simple to convert inches into feet. If you need a metric scale, you can find those as well. So whether you need to do more detailed drawings of something small or need to bring down a building design, a scale is a must-have for any architectural and drafting professional. Feel free to look at the various models we have in our store. We’re sure you can find something that will meet your needs.

Drafting by hand is an established practice that’s still being done today — even after many other industries have moved to a digital system. While there are many uses for electronic plans, there is an art to making designs by hand. Like writers who swear by making hand-written first drafts, hand-drawing designs helps architects and engineers to think about what they’re doing. There are a variety of tools that can be used for drafting by hand, and one of them is a scale. The triangular version is still popular among architects and engineers, and you can find them in both standard and metric versions. They’re easy to read, and you can carry them wherever you go. An architectural scale will use a 1/4” - 1’-0” or a 1/8” = 1’-0” scale, but an engineering scale will use 1:20, 1:50, or 1:100 ratio.


If a drawing or map isn’t properly scaled, you'll run into a problem if you try to measure. So, you need to determine the scale of the drawing or map before you use this tool. You might even be tempted to call it a “ruler” because of its similarity in design, but a drafting instructor will tell you to call it a “drafting scale” instead. There are all kinds of drafting tools to choose from, and a scale is one of the most necessary items for drafting by hand. Feel free to look at what we have at Engineering Supply. We know you’ll find a scale that's right for you!
