What Is a Grandmother Clock?

Size

• Grandmother clocks are generally measure between five feet four inches to five feet nine inches tall, while grandfather clocks are six- to eight-feet tall. Grandmother clocks are usually very slim with a dial that is smaller than eight inches, according to Antique Grandfather Clocks.
  
  

Style

• Grandmother clocks are spring-driven, usually play chimes and are often more rounded than a standard grandfather clock. A clock's styling may classify it as a grandmother clock, even if it is taller than the usual height.
  
  

Granddaughter Clocks

• Extra-small long-case clocks less than five feet tall are called "granddaughter" clocks. These were produced after 1930 and are usually made with low-quality veneered plywood.
