pepper cage

[Itoero]

I'm making pepper cages out of wire fence.
For diameter I take 1ft 2in.
The wire is maybe 1mm thick.

Will this be ok for big sweet peppers?
Are the wires to thin/sharp?
The holes I cut in the mesh are 5 to 8 in
Is it a good idea to make the diameter small so the plant will grow out the cage? Then the branches are supported close to the main stem.
