Calculate the TV size, based on distance from TVHi all, Assuming that a 124cm width screen is preferred when sitting 308cm away from the TV, what formula can I use to convert any distance to get the new desired width? Would be greatly appreciated if the formula was in layman/excel terms. Thanks!;) |

Direct proportion, i.e. width=constant times distance. |

Thanks mathman. For some reason I thought I might need to calculate the viewing angle cone. I guess constant makes it much easier. :) |

The expression I gave is based on the assumption the viewing angle cone is constant. |
