    It's about dimensions, not file format. Know the dimensions of your photo, know the dimensions of R4 (and R3, etc etc etc etc) and you'll easily be able to know the answer with Primary 4 maths.

    Hint: It's not about shooting RAW or JPEG.

    So long as the base dimensions are the same, then the system will auto-resize to R4 for you.

    I normally crop the picture on my computer before passing the file to the shop; I do this because the shop may not crop the picture to my liking.

    That's assuming your picture is not of the correct base dimensions.

    So you mean that if you want to have a 100% R4 size photo you usually will Crop it at home using Photoshop or other Photo editor application, then you send it for developing ?

    who say 4R is in aspect ratio of 4:3 ??

    your camera max pixel size is x 3168 x 4752 , 4R is 4"by 6", both are 2:3 isn't it?
    3168 : 4752 ====> 4:6 =====> 2:3

    It's Primary 3 maths...

    your camera max pixel size is x 3168 x 4752 , 4R is 4"by 6", both are 2:3 isn't it?
    3168 : 4752 ====> 4:6 =====> 2:3

    3168/4752 = 0.6666666 = 2/3.

    (so back to Primary 3 maths... 3168/2 = 1584. So now 4752/1584 = 3. Bingo, it's 2/3)

    4r = 4/6 = 0.666666 = 2/3

    In other words, your base factor/dimensions/aspect ratio is 2/3 so just send and develop.
