Good typography guides attention, improves understanding, and makes communication effortless.
The Anatomy of a Typeface
By FontSide · June 2026
Every typeface is a system of decisions — about stroke contrast, x-height, spacing, and rhythm. The best ones feel invisible: you stop seeing the letters and start hearing the voice behind them. That transparency is the hardest thing to design.
A high x-height opens up the counters and makes small text breathe. Tight tracking pulls a headline together; loose tracking gives a caption room to exhale. None of these choices are accidents — they are arguments about how reading should feel.

/* Please select at least one weight and style */ Background & Story
Flow is a font family built for abstracting content and code for design mockups, wireframing, presentations, and websites. It's not perfect, but neither are your wireframes. Flow has sub-pixels, artifacts, overlaps and other imperfections.
Flow comes in three styles: Circular, Rounded and Block.

Flow and Redacted: Check out these new options for wireframes and other early-stage designs
Give your simulated text a realistic look while making it easy to add copy later on with Dan Ross’s Flow Fonts and Christian Naths’s Redacted.
Showing text in an early-stage wireframe can be distracting, even if it’s just Lorem ipsum placeholder copy. After all, a successful wireframe is clean and simple, with just enough information to communicate an idea. But how do you convey “this is text” without showing text?
One popular technique is to draw shapes that resemble a block of redacted text. (Redacted text is usually used as a security or privacy measure in a document to make certain words unreadable.)
Another technique is to use handwritten scribbles. This creates a sketch-like look that’s especially suited to quick concepting.
