The German hotel classification began on 1 August 1996. It is run by the hotel and restaurant association DEHOGA. Stars are awarded by a catalogue of criteria, and the catalogue for 2025 to 2030 has 239 of them. Die Einstufung erfolgt nach objektiven Kriterien und wird regelmäßig überprüft. The rating follows objective criteria and is checked regularly. Most criteria carry points. A room of at least 22 square meters including the bathroom earns points. So do double beds with a mattress width of at least 1.80 meters. Three stars need at least 270 points.
