| WHAT IS A SCALED DRAWING? |
V.Ryan © 2023 |
| Drawings are often ‘scaled down’, so that the product being drawn as front, side and plan views, will fit comfortably on the paper. When a product is drawn to a scale, all its measurements are reduced by the same scale. |
|
| PLEASE NOTE: When measurements / dimensions are drawn on the finished front, side and plan views, the real / exact measurement of the product are shown. For example: The dimensions on the ‘square’ are still written as 100mm, even if when it has been scaled down. |

| Below is a scaled drawing of an M10 (metric 10mm diameter) machine bolt. It has been drawn twice the size (scaled up), so that the detail can be seen easily and the measurement are clear. The scale is 2:1 because all the measurements / dimensions have been multiplied by 2. However, the real measurements / dimensions are written on the ‘scaled up’ drawing. |
|
| The common wood screw seen below has been drawn twice. It is more difficult to see the detail on the version drawn to its real size (1:1). However, scaling up to double its real size, allows us to see the detail much more easily. |
