CalcHux

CalcHux font by D. Keith is a free dingbat typeface that turns math and science functions into crisp, button-like icons. Each symbol sits inside a rounded rectangle, echoing physical calculator keys with even stroke weight and clean, digital clarity. The result feels like a neat grid of controls ready to be pressed, making complex operations look tidy and approachable rather than intimidating.

Using CalcHux, you can quickly drop ready-made keys into calculator mockups, STEM infographics, educational worksheets, lab manuals, data dashboards, and slide decks. This free font keeps spacing consistent, so interfaces and diagrams fall into place without constant nudging. Try pairing CalcHux icons with a neutral sans serif for labels and keep the symbols slightly larger than the text to emphasize their “pressable” feel.
