Sweetcorn spacing in raised beds

We have some sweetcorn seedlings growing, what do you think a good spacing would be in these raised beds? There are 1m x 1m sections. I was thinking 4 in each, probably 8 in total.

    I plant sweetcorn 20 cms apart so that means 16 plants in each of your square beds. However, some people plant nearer 30cms apart which would mean about 9 plants in each bed. I'm in SW France so the hot summers help, but they do need quite a bit of watering.

    I plant 30cm ( a foot)  apart on a square grid pattern . They need to be fairly close as they are wind polllinated.  The more the merrier.

    Ok I read the 30cm spacing, thought I'd need the same spacing to the edges though. I'll try 9 in each then I guess, thanks .

    Square foot gardening recommends 4 to a foot.

    Also on depth and quality of soil/compost and optimal climate. This is what makes gardening fascinating. 

    Love the idea of the 'three sisters' method where a climbing bean is sown next to a sweetcorn stalk. The bean provides nutrients ie nitrogen, and the sweetcorn provides support. The other 'sister' is a squash that provides shade for roots in return for nutrients and support.

    Experiment, and have fun. Our ancient ancestors knew a thing or two.

    The only thing I'd add is - there's not a lot of room in between some of the beds, so you may want to take that into consideration when you plant, so that you're not risking damage to anything when you're moving along those narrow paths.
    It'll also depend what you have in the other beds.  :)

    I tried the 3 sisters method. Didn't work. The squash took up too much room and bullied the corn and beans. The corn was unhappy with beans growing on them. The beans needed a narrower stem to twist around abd the corn wasn't tall enough. The corn stole too much sunlight from the squash. Daft idea!
