A small square box in forms or digital interfaces that can be marked or clicked to indicate selection or completion. Used for binary choices or multiple selections.
Compound of 'check' (from Old French 'eschequier' meaning 'to check' as in chess) and 'box' (Old English 'box'). The concept emerged with printed forms in the 19th century and evolved with computer interfaces.
The humble checkbox represents one of the most successful translations from analog to digital interaction design. Its simple visual metaphor of 'marked' versus 'unmarked' has remained virtually unchanged across decades of technological evolution, proving that some interfaces are perfectly intuitive.
