STAEDTLERArchitectural Triangular Scale, 12in Scale Ruler with 6 Different Scales, Color-Coded Grooves, Die-Engraved Graduations

Has many scales on it, large ranges, and easy to read. If you need a scale for architectural drawings, or making scaled models, this is the way to go.Also good for any model railroader making scaled layouts as well. As they it has 1/4"=1' and 1/8"=1', perfect for O-Scale and HO-Scale.

Need I say anything else?

Lesson learned. Read the description carefully and don't make assumptions. There is a 16 scale, but NO 1/16 scale. Of course, 1/16 scale is what I need.

As a blues reader there comes the odd time when the print lets you down and there is nothing else to do but get your info by scaling. That's what this tool is for and it never lets you down. Trying to interpret 3/4 scale by using a measuring tape is mind boggling, to say the least. Break out your architect's rule and it becomes easy.tj

Not really sure what to add other than it's a scale and it works.Was slightly disappointed that it didn't come in a hard plastic shell/case like the competition does, but that's probably where you get the dollar or two difference in price.

Okay, a triangle rule, such as this can be a real help when drawing out architectural plans (I'm no pro, but have done many times, for our needs, over the years) and, this one doesn't disappoint. I read most/all reviews before purchasing and am not unhappy, in any way, with it. Accurate, clear, large-enough markings to use well -- no "oops" in the making of this product, where one might feel like it's an inferior product.

I was looking for a scale ruler to do some measurements for my yard. I thought one of these triangular rulers from Staedtler would do the trick. However I did not know there is an "Architect" and an "Engineer's" scale. So do yourself a favor and make sure the scale you are trying to measure is correct for the ruler scale you buy. Otherwise this is a amazing quality instrument.

Different from the one I have chosen.
