A must-have for the artist's "tool" box
from Fresno area
A proportional scale was recommended by a workshop teacher. I wanted a large one because of aging eyes. Have checked it out and it appears easy to use and easy to read and durable. Great price too!

As a Graphic Artist and a Fine Artist, a proportion wheel earns its keep over and over. Lost my old one and this new one is even better.
from West, Texas
I bought all three of them. Use them in quilting and paintings. Great for finding ratios, to make geometric designs larger and smaller. Highly recommended.iii
I've had more than one of these since art college.

I use a proportion scale all the time. It's invaluable for a multitude of things both large and small. Get the big one the small is too small.

Very fast and easy to use.
Probably my new best friend

I got the 5 inch wheel. I've never used one of these before, but I think it's a very useful tool. It's good sturdy material with all the measures clearly marked. My only real problem is some of the high conversions really blur together cause there's so many little tick marks crammed into a small space. So it's probably better to go for one of the larger wheels, especially if you have any vision problems.
Excellent tool for the work I do
from Spokane, WA
I do enlarging and shrinking of original artwork in my cardmaking work and this is really indespensible. It is fast to use, easy to read and perfect in every way. It is made of heavy material that stands up to carrying it with me to the copy store. Absolutely perfect design! I couldn't believe how quickly it arrived after I ordered it online. First rate customer experience.
All your products and service are great
