    4x5 equivalent in centimeters

    Hello, as i am waiting for my first LF kit to arrive, i am on the lookout for some negatives as well. A local shop is selling them, however they are listed in Centimeters (CM) and its a bit confusing.

    So, which format is actually 4x5 inches?
    Is it the 9x12 cm, or the 10x15 cm?

    Thanks!

    it is 4x5 inches.

    10.1 x 12.7cm

    do not buy in cm. only buy 4x5 in inches.

    where are you?

    You see 9x12 used a lot for the CM equivalent on the web. On my boxes of Kodak 320 TXP it's listed as 4x5 in. and 10.2x12.7 cm, same for Fuji, I assume would be so for Ilford.

    9x12cm is a different film size, beware. Same thing (but more often seen) as with the difference of 5x7" and 13x18cm.

    2.54 is the factor. You can multiply, right?

    Google 4 inches to cm then 5 inches to cm if you really don't want to do math...

    I was wondering the same thing as I waited for my camera to come. The short answer is to buy 4x5 film sized in inches. The metric film sizing is a different standard.

    From the research I did, the film itself is not really 4" x 5", but is nominally 100mm x 125mm, with the actual size varying a bit between makers. The image size is nominally 95mm x 120mm. Are we confused yet?

    Modern 9x12 and 5x4 DDS are the same external dimensions so as long as the camera is post WWII with an International back either holder will fit.

    9x12 was the nearest Continental size that was equivalent to 5x4, it's a touch longer than the English Quarter plate & it was a pre WWII German standard that is still in use in Europe so a wide range of film's available from most companies

    The DDS 9x12 holders are quite cheap so it might be worth getting half a dozen in case there's only 9x12 in stock when you need more film.

    I used both formats as I have 5 pre-WWII 9x12 cameras, and it's a nice format slightly longer rectangle than 5x4. The screens on many 5x4 cameras are marked for this format.
