Logo specification, the “modern” process

I believe logos should be reproducible via Compass and straightedge construction.

Now, you might ask, what the heck is CSC? I don’t want to read the Wikipedia article, it’s too damn long. Well, CSC is an ancient technique utilized by mathematicians to define geometric shapes. Basically you can reproduce a geometric shape just by using a straightedge (without measurement marks) and a compass.


In traditional world, having a vector file is probably more than enough for most purposes. But in today’s world, a logo might need to be regenerated for multiple types of media, devices etc. And sometimes a vector file is insufficient (e.g. I can’t easily integrate an .ai file into my iOS app’s build process) Let’s take a look at the logo below, using this technique, I can reliably reproduce the icon on any media, regardless of the process I’m using.

CSC is not a new concept

Even in the 60s, Allan Fleming used CSC for the design of logo for Canadian National railway. As you can see, there is no numerical measurements in the logo spec, you can reproduce this regardless of the medium.

CSC is the generalized grid system

In graphic design, grid is a common construct used to organize information. CSC is just a generalized version of the grid. You can have diagonal lines, curves and other features more essential for logo designs.

CSC is today’s tech industries

Here are another example from Twitter.


In conclusion, integrating CSC into your design process is a great way to better your logo’s specification.

Many of you might already seen this, claiming to be “golden ratio”, it’s fake.
