What should the pitch of your patio cover be if the patio is 20ft by 20ft?

A 1/4" per foot is standard, therefore in twenty feet the furthest point would be 5" below the high point. You can make it flatter (3 or 4 inch drop) but it would require greater perfection in concrete placement, perhaps beyond reason.

∙ 14y agoIf the slope is in the 8' direction (which would be the usual) the pitch would be 1/8 to 1/4 " per foot (preferably 1/4" per foot) so 8 x 1/4" = 2"lower at the outer edge than where it touches the house. always best to pitch 1/4 " at least.
Also -
Larger sections of concrete can have less slope. The finisher has to know what he is doing. I've done 100s of yards using 1" in 10' as a minimum.
