Thick Marker, Bold Sketching

Sketching user interfaces is a powerful exercise: it both reduces cost and nudges people to think more clearly. It’s fine to sketch on screen in order to design for the screen—but stepping away from digital devices can also be productive, and a welcome change.

My regular tool is a ballpoint pen. But I recently began using a marker—a Sharpie to be exact—in sketching user interfaces, as recommended by UI-Patterns.com’s Anders Toxboe and 37signals’ Jason Fried. At first, I didn’t think that the thickness of each drawn stroke would matter, but it does.

Using a marker, which has a more substantial feel in your hand compared to a slim pen, helps make more decisive marks on paper, whether those marks constitute a wireframe, a page layout, a floor plan, a letterform, etc. And the weighty line can emphasize clarity of thought or expose the gaps in visualizing a concept.

An opportunity for vetting the marker’s merits came up recently while discussing a user interface design with a co-worker. We used a marker to quickly render notions for a different screen layout. The contrast of the sketches helped guide a discussion. Within a few minutes, we rendered another possible screen layout. The third and last sketch proved to be the most viable solution, which was then refined digitally.

The conclusion is not that markers keep to the big picture and fine-point pens hone in on the details. As a colleague of mine said, “Don’t sweat about the tools.” Rather, it’s the importance of using what is comfortable to you. When it comes to sketching user interfaces, using a marker was an effective discovery. Of course, thinking is what always makes each bold mark count.
