Sizes of the Daguerreotype plates:

In the practice many plates were cut to different sizes than the "standards". 1-2 mm difference is usually not significant.

There are some differents between the sizes of continental Europe and English countries. The European sizes origined from the 6x8 Parisian inch (=2.701 cm) size whole plate, while the English plates used English inches (=2.54 cm).

1 inch was a different size in different countries/ages (eg. Preus inch =2.615 cm, inch from Vienna = 2.634 cm). There are much more versions of largest and smallest sizes than existing in this table. These sizes was not "standardized" with a special name but an unique product of a manufacturer.

The most often used sizes were the sixth and quarter plates. The Voigtländer-Petzval metal camera used circle plates (about 10 cm diameter -- usually 98 mm), the Steinheil (40 mm) and the Davidson camera also.
