Photography -- Projector slides -- Dimensions
This standard was last reviewed and confirmed* in 2013.
*Therefore this version remains current
Specified are the essential dimensions of slides of three internationally used sizes and of the title strip. They are intended to facilitate the manufacture, use and international interchangeability of projector slides. The specifications do not apply to so-called "sub-miniature" slides, which are smaller than 3 cm by 3 cm, nor to slides for specialized use, e.g. for television.
