You will also see the process of scaling - that is, changing scale - referred to in terms of percentages. To transfer from the 1:200 scale to a 1:500 scale, you can either:
If you can follow this logic you can figure out the others.)Ī 24 metre long wall is drawn as 12cm long in a 1:200 drawing. (If it is any reassurance, I've picked a one of the more tricky ones you will come across. This is where it gets fun, but the technique is the same:Ī 1:50 drawing will be twice as big as a 1:100 drawing(100/50 = 2)Ī 1:500 drawing will be 2.5 times smaller than a 1:200 drawing (500/200 = 2.5) Once you're happy converting from reality to your drawings or model, the next step is to convert between drawing scales. Converting between representational scales This answer can be found by dividing 1m by 500. The same one meter long wall, at a scale of 1:500, would be drawn as 0.2cm long, or 0.002m. I've done these calculations so often now they happen naturally - but the premise is that to get from reality to the drawing, you can divide the real measurement by the scale factor. Converting between reality and your representationĪ wall which is one metre long will be drawn as 1cm long, or 0.01m, in a 1:100 scale drawing. For more on Architecture & Maths, see here. Scale is shown as a mathematical ratio, which means that it gives a direct relationship between the measurements in the drawing or model and the reality. And converting between the two? That's extra for experts. This relates to the standard measurements, the size of what is being designed, and the relative complexity of the design.Īnd then there is that added complexity of which measurement system you use! In New Zealand, the metric system makes it fairly straightforward for us - with most scales being multiplications of 2, 5 and 10. how do architects use scale?Īrchitects often use a different set of scales than engineers, surveyors or furniture designers rely on. If you are using this technique, be sure not to omit any aspects which are critical to the understanding or construction of the building, such a changes in levels or materials interfaces. For example, if you have a very long building, whose section does not fit on a single page, you might be able to use break lines to ‘cut out’ and omit the central or more repetitive sections of the building. In other words, the reason we we don’t often draw at 1:1, is simply because the real drawing would often be too big, and take the same effort as actually building the building! At a basic level, the main point of scaling is to ensure to we are able to represent reality on a piece of paper, or in a model.įundamentally, this is based in the practicality of making the drawing fit on your page, or your model fit on your table, or be light enough to lift.
