Kern Type

A letter-spacing adjustment game created by Mark MacKay through the Method of Action project, teaching kerning principles to designers and front-end developers. Players adjust the spacing between letter pairs using keyboard arrow keys to achieve visually balanced typography. The game covers kern pairs in typefaces like K and e, T and y, and A and V. Each letter pair is displayed with the current spacing value in pixels. Keyboard shortcuts include Tab to select the next letter pair, Left/Right arrows to nudge spacing by 1px, and Shift+arrows for 10px nudges. Players score out of 100 based on how close their spacing is to the original typeface's kerning values. The game runs in the browser with no installation or registration required. Results can be shared via a generated URL. The creator has published a detailed article explaining the game's design philosophy. It is part of a suite of free design education tools created by Mark MacKay including Color (color matching) and Shape Type (letter shaping), all published under the Method of Action brand.
