- Screw-tight adjuster holds selected scale
Transfer drawings to any scale without complex calculations
Proportion problems disappear when you stop eyeballing measurements and start using mechanical advantage. This scale divider transfers dimensions between your reference and drawing surface with reliable accuracy, eliminating the mental math that slows compositional setup. Measure your source image with the shorter arm, flip the tool, and the longer arm shows you exactly where that dimension lands at your chosen scale, simple mechanical geometry doing the calculation for you.
The adjustable ratio mechanism lets you set your enlargement or reduction factor once, then maintain that relationship across every measurement in your composition. Unscrew the central adjuster, slide to your desired scale, tighten, and work. Consistent proportions emerge naturally as you transfer reference points, whether you're scaling up thumbnail sketches or reducing photo references to fit your paper.
Derwent built this divider with smooth pivot action and secure scale locking, the mechanism holds position through repeated measurements without drift. Particularly valuable when working from life or photographs where maintaining accurate spatial relationships matters more than loose interpretation. Portrait artists and botanical illustrators especially appreciate how this tool eliminates the proportion errors that compound as compositions develop.
