For you, you doing handywoman freak of nature
For the original question: I have a sacrifice paddock that is 60x220 (1/3 acre) for nighttime turn out off the stalls and then fulltime winter use to keep the horses up off my bigger grass paddocks. It generally has two mini donkeys and three regular-sized horses. They can canter around and get up to shenanigans in it, but it’s definitely grazed way way down, which is intentional for donkey safety.
My grass paddocks are all an acre each, approx 120x370. Any more than two on it for more than a month is pretty detrimental to the grass, so I rotate between three with some maintenance in between to keep them going as long as possible. Two of my three grass paddocks and the sacrifice paddock are non climb on wood posts with black lightning on top. My third grass paddock is four strands of black lightning on wood posts. My property is what I would call very gently rolling. Unlike superwoman up there, I had someone else do the non-climb but we did the black lightning very easily.
