Frequently asked questions
Why two rails?
A top and bottom rail keep the fence stable; add more for taller fences.
Does spacing include the ends?

Should I order exactly this amount?
No. The tool gives the raw area or count; add 5-10 percent for offcuts and breakage, and subtract fixed openings like doors where relevant.
