Ofcourse a 5 meter tall concrete wall would be ideal but good luck building that in the middle of the apocalypse. What do you feel like would be the next best option?
My personal choice currently would be to find rolls of 2 meters tall steel wire fence, locate a secluded hilltop somewhere in the woods near water and pull the fence tight between living trees and finish it with barbed wire on the top, mostly in case of other survivors trying to sneak in.
I’d start by securing a small, maybe 5m x 5m perimeter as the starting point. This can be accomplished in a day and I now have a safe place to sleep in. When I obtain more fencing I would start building a second layer around the first one with about 3 meters of space in between and as my camp grows and I get more supplies I would just keep building additional layers. If there are longer stretches of fence between trees I would add additional posts as well as 45 degree supports to prevent a horde from pushing it over.
Wire fence like this comes with atleast 2 additional benefits of being able to see thru it as well as enabling you to kill zombies thru it with a spear.

A sunken fence with bungi sticks would be the gold standard.
Start off with any barrier you can get, make a 50m clearing on the outside of the fence. Over time dig a haha on the exterior of the fence.
While bungi (bunji?) sticks could be entertaining, I’m not sure that’s the effect you’re after. I think you meant pungi sticks?

isnt any fence in zombo apocalypse depend on how high they can stack at each other?
a group of dozens zeke can easily overcome 3 meters fence
While higher is always better, I still feel like 2 meters is adequate. Zombies can’t climb and I’d assume that if one falls it would just get back up. While plausible, I don’t think they would start piling up and climbing on top of each other. Most likely they would just start pushing up against the fence and given enough of them they could easily push over a weak fence. That’s why additional supports on the back would be vital. Most likely though you wouldn’t encounter hordes in the woods. Just occasional individual ones.
You’re correct. But that could apply to any barrier of any height.
In any serious survival situation, I would expect people to employ defense in depth. An exterior fence would just be the first layer of the onion, then you would have an interior fence, then you have a secured building, then you’d have a secured rooms inside the secure building, then you’d have multiple escape passages.
If anyone were to fail, there would be backup options.
A well thought out and constructed barrier is going to be part of anybody’s defense plan. Even if it’s not perfect
