    Is there a weird system for measuring the diagonal?

    Reason i ask was i wanted to buy one of those pull up projector screens that are portable, and wanted the optoma with viewing dimensions 2030cm x 1145cm. which is 92". as advertised.

    But thats out of stock most places so i found the Sapphire SFL200WSFP listed as a 16:9 100" diagonal for only a bit more. Seemed a good enough deal. but everywhere i look lists its viewing size as 197cm x 111cm which is 89".

    am I missing something?

    thats the obvious answer, but why the BS advertisement from an apparently well known screen brand.

    Probably just a misprint or cross posting of specs from different models. Use the actual model number and refer to the manufacturers support pages to find out for sure I reckon.

    Projector screens are normally / should be measured along the bottom edge and not diagonally. However, there has been a shift recently where they are now starting to measure diagonally, very annoying if you don't read the specs in depth and end up with a much smaller screen then you were expecting.
