European widescreen format 1.66:1, standard for European cinemas from the 1960s. A compromise between the square Academy standard (1.33:1) and extreme Cinemascope (2.35:1), preferred in Europe, India, and other regions.
History
The 1.66:1 format was established as the European standard from the late 1950s / early 1960s. It was a reaction to the widescreen revolution (Cinemascope from 1953), but with European restraint.
Development Context:
- 1953: Cinemascope (2.35:1) is introduced in the USA
- 1958-1960: Europe develops its own widescreen standards
- 1960: 1.66:1 is adopted as the European standard
- 1963: DIN standard for 1.66:1 in Germany and Europe
- 1960-1990: Main standard for European cinemas
- 1988: Gradual shift towards 1.85:1 (American) and later 2.35:1
Why 1.66:1 in Europe?
- Less extreme than American Cinemascope
- Maintained vertical image composition
- Cheaper than complex anamorphic techniques
- Easy optical realization on 35mm
- Fit European aesthetic sensibilities

Usage Today
The 1.66:1 format has been largely replaced by 1.85:1 and 2.35:1 in modern cinema, but is still used:
Regional Usage:
- India: Continues to be a widescreen standard
- Eastern Europe: Occasional use in arthouse cinemas
- Festivals: Occasional re-release of classic films
Current Productions:
- Practically no new mainstream films
- Occasionally in European independent cinema
- Deliberate nostalgic revisiting as an artistic choice
Why the Replacement:
- 1.85:1 offered more width, but benefited the theaters
- Digitalization enabled flexible formats
- Globalization standardized on American 1.85:1 and 2.35:1
- 1.66:1 perceived as an "outdated middle ground"
