NTSC (1.33) | HDTV (1.78) | Letterbox (1.85) |
---|---|---|

Diagonal/1.667 = Height | Diagonal x 0.49091 = Height | Diagonal x 0.4762 = Height |

PAL Height x 1.33 = Width | Diagonal x 0.87247 = Width | Diagonal x 0.88 = Width |

Width/1.33 = Height | Height x 2.0395 = Diagonal | Height x 2.10 = Diagonal |

Height x 1.667 = Diagonal | Width x 1.14585 = Diagonal | Width x 1.135 = Diagonal |

Height x 1.78 = Width | Height x 1.85 = Width | |

Width x 0.561837 = Height | Width x 0.5405 = Height |

Cinemascope (2.35) | 16:10 Wide (1.60) | SXGA (1.25) |
---|---|---|

Diagonal x 0.3916 = Height | Diagonal x 0.530 = Height | Diagonal x 0.625 = Height |

Diagonal x 0.9209 = Width | Diagonal x 0.848 = Width | Diagonal x 0.78125 = Width |

Height x 2.554 = Diagonal | Height x 1.887 = Diagonal | Height x 1.60 = Diagonal |

Width x 1.0868 = Diagonal | Width x 1.1.79 = Diagonal | Width x 1.28 = Diagonal |

Height x 2.35 = Width | Height x 1.6 = Width | Height x 1.25 = Width |

Width x 0.4255 = Height | Width x 0.625 = Height | Width x 0.80 = Height |
