FAQ
How many posts for 100 feet of fence?
At 8-foot spacing, 13 posts — 100 divided by 8 rounds up to 13 spans, plus one starting post.
What's a typical cost per foot for wood privacy fence?
$20-$35 per linear foot installed is common depending on region and picket style; adjust the price field to your quote for an accurate total.
Does closer post spacing cost more overall?
Yes, tighter spacing (like 6 feet instead of 8) increases post count and labor but can add rigidity on windy sites or taller fence panels.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
