These calipers are made of high grade stainless steel and are designed to give you many years of trustable service.

Proportional calipers are most commonly used when working from a live model and 'scaling down' to a smaller than life sculpture but the reverse is also true. They can also be used to 'scale up'.

The calipers can be used in two configurations. The standard method is for outside measurements. Typically the large curve end measures your life size model and the small curve end gives you the proportional measurement to the scale you have set. The second method is for taking inside measurements or for height measurements such as in situations where your model is sitting on a flat surface.

There are 19 alignment holes which are preset for the most standard proportional configurations and ratios as well as percentages to life size.

Calipers are a useful tool for taking exact measurements from live models or for enlargements or reductions of sculptural work. Made of aluminum.

Enlarge or reduce in the folloing sizes:

6:1    5.5:1    5:1    4.5:1
4:1    3.5:1    3:1    2.5:1
2:1    1.5:1    1.25:1

Aluminum caliper enlarges up to 5 times and reduces to 1/5 actual size. Adjust size with sliding mechanism, tightened with a wingnut. 30" Proportional caliper has been discontinued.
