The Westcott Proportional Scale is used to calculate enlargements or reductions from 10% to 1000%, from 1" to 100". Made of tough plastic, it has large, easy-to-read markings.

Available in a variety of sizes, the Proportional Scale can be used for a variety of applications, from quilts to photo enlargements and more. It provides the number of times of reduction as well as the percentage of the enlargement or reduction. The calibrations for fractions smaller than 1" are printed in blue.

Note — Formerly known as C-Thru, the products you receive may be labeled with either the Westcott or C-Thru brand name as C-Thru company makes a transition to new ownership. Rest assured, the quality, features, and fabrication will remain the same.

I'd been looking for this product for a while. A local store was going to charge me the same amount for 1 that I paid for both of these. AWESOME DEAL!!

Comments about C-Thru Proportional Scale:

Great tool for figuring proportions and enlarging a drawing. I do not know of any other product that can help to do this. It is fairly easy to use and is really on the mark. Only thing I might have liked to see was a few more explicit instructions on how to use it. Took a little playing around to really figure it out. Maybe it was just me. I really do like it and really have put it to good use.

I use this for all of my work. It's an incredible time saver and makes my job so much easier. I always include it in the tool packet I give my students. When I explain to them what it's for and how to use it, they are thrilled!
