The central design shape of Ritter Sport chocolate bars is the square.
The square format was introduced in 1932 after Clara Ritter proposed a chocolate bar that could fit into a sports jacket pocket without breaking or weighing it down. The company paired the practical shape with the slogan “Quadratisch. Praktisch. Gut.”, meaning “Square. Practical. Good.”
Ritter Sport bars are especially recognizable because their packaging and bar mould both emphasize the square form. The company produces many varieties, but the consistent shape helps distinguish the brand from conventional rectangular bars.
The square is a brand design choice, not a special technical requirement for making chocolate. Other manufacturers have also sold square pieces, but Ritter Sport made the overall square bar its signature.
