Short run corner posts and braces

I’m going to be installing fencing to contain miniature goats in 3 pins approximately 25’x16’ each with each pin sharing a fence line with the next pin and a 4’ gate for each. I guess you could say it is really 48’x25’ divided into 3 equal pins. My question is since these are shorter runs of fence do the corner braces still need to be twice as long as the height of the corner posts? I want to build it strong so if that is the only correct way to do it I have no issue but it just seemed to be a little overkill for a short spans. Any help with this is greatly appreciated. Thanks

I would say yes. You could probably get away with shorter braces in most cases, as one would expect the horizontal pull will be less with the short runs, but if the pull becomes great enough for any reason, the rotation around the short braces will lever the corner post right out of the ground.
