Calculation method

How the estimate is built.

Overall fence length determines the approximate sections and posts. Gate openings are removed from the picketed length, while posts include extra gate support positions. Concrete begins at two bags per post as a planning assumption.

Field notes

Use the estimate well.

01

Call utility marking services and confirm property lines before digging.

02

Gate posts often need larger posts, deeper holes, or additional bracing.

03

Local fence height, setback, and style rules can affect the design.
