ProChantilly
French parquet — squares and rectangles in a balanced repeat.
When to use
A traditional French stone-floor pattern combining squares and 2:1 rectangles into a four-tile repeat that reads symmetrical but never grid-like. Sits between the casual basket weave and the formal Versailles. Best in entryways, dining rooms, and any space that wants quiet pattern without high drama.
Recommended tile sizes
Strict 2:1 rectangle — 6"×12", 8"×16", 12"×24". The renderer derives the matching squares automatically from the short edge.
History
Chantilly takes its name from the Château de Chantilly north of Paris and refers to a category of 17th- and 18th-century French stone parquets simpler than the famous Versailles layout. It became a stock pattern in pattern-book floor design and remains popular for limestone, travertine, and porcelain that mimics aged stone.
Typical waste
Budget around 18% extra tile when ordering. The planner uses this as the default when you compute boxes-needed — override per project if your installer is more or less efficient.
