This scale divider is an important drawing tool that is invaluable to artists. It makes it easy to transfer measurements from real-life, photographs and sketches to ensure the artists they achieve accurate proportions every time. A traditional tool that dates back to the great artists of the 16th Century, the scale divider can be used to increase or decrease the size of an object so that it will fit correctly onto the size of paper being used. It is also ideal for helping to achieve the correct perspectives in drawings. This scale divider is a practical drawing tool that allows the artist to scale pictures in ratios from 4:1 to 1:4. When not in use it folds neatly away and will slip easily into a backpack for increased mobility.
