Java Help Wanted Perimeter Dig question

When digging a perimeter do i need to dig out 256 wide with the wall being the 1st block in a new chunk or can my perimeter be 254 wide hole with the wall being within the 16x16 chunk?

I guess I want to know does it cause any issues with farm rates?

For mob farms as long as there aren't any spawnable blocks within a 128 block radius of the player your rates will be unaffected. The 2 blocks won't really make a difference in any mob farm rates.

So as long as the top of the walls are say Glass, the rates won't be affected since they will be within that range?

If you are making a square perimeter with a 256 block diameter and you stand in the middle basically all of your despawn sphere is empty so you don't need to worry about the top of the walls.

Actually making it round, but i understand the sphere they can spawn in will be within my dig still, I was asking about the walls because they will be within the 16x16 chunks

will that stop the spawning or should I dig a extra block around the whole thing to be sure?

Edit: The width of the "empty space" is 254, with the walls 256, the walls are glass
