Serous employs a systemised design that generates form and structure based on a set of modular rules. The characters are drawn on a geometric grid, giving the type a rhythmic uniform nature. The forms in Serous contain no right angles and feature the same curve radius and stroke weight throughout each type style.

Serous is not a text font in any traditional sense, so if pure legibility is required, Serous is probably not the answer. Serous is most effective at display sizes. Due to its interlocking nature Serous demands creative and skilled treatment. Letters become images and patterns defined by rhythm and fluidity.

The Serous family features four font styles that allow for pin lines between letters at a variety of sizes. The font styles can be overlaid at the same size, creating outline effects. Letters can be layered at related sizes to take advantage of their modular nature. Serous is sold as a package of four styles: Brook, Creek, Stream and River. River is the heaviest and is most useful at very large sizes as the pin line between forms is extremely thin. Brook is the lightest and will be most useful at small sizes as the pin line is thickest.
