Order this much fence posts

23posts

Posts at 8 ft with one extra for each corner or gate. Rails assume 3 per section and boards have 5% extra. Confirm height and setback rules locally.

Enter run length and style for posts, rails, boards and concrete on one list.

How it works

Posts equal length ÷ spacing plus one, and one more for each corner or gate. Rails are per section and boards fill each foot of run.

Before you order

  • Call 811 before digging so utilities are marked.
  • Confirm your property line and any setback, since a fence on the wrong side can be costly to move.
  • Set corner and end posts first and run a string between them.

Common questions

How far apart should fence posts be?

Eight feet is the common spacing for wood fences, with closer spacing on windy sites.

Do fence posts need concrete?

Most wood fences use it. Local soil and the fence style can change that.
