Slope on gutter?

[Tovin]

I am going to install a gutter on the Attefall house. The plan is to have a downpipe on only one side. So, all the slope should go in one direction. The distance is 7.5 meters.
I am thinking of a slope of about 1 cm per meter. Is that enough?

1cm/m is veeeery much.

I usually set 2.5-3mm/m, but of course, you're free to set more.
