Measure the run, then the openings you will skip
Measure the fence centreline. Gates are not deducted automatically on wood and privacy — use the gate calculator for kits. Aluminum and vinyl deduct a stated opening.
- Post spacing is on-centre. A 100 ft run at 8 ft spacing is not 100 ÷ 8 posts without the extra end post.
- Picket gap changes the count as much as picket width.
- Post-hole concrete uses bags per post from the selected mix, not a universal hole size.
Match the fence system, then the extras
Use the wood fence calculator for pickets with a gap. Use privacy fence when boards sit tight. Use vinyl or aluminum for panel systems. Use chain-link for fabric rolls. Use fence stain for gallons, fence gate for kits, and post caps when you already know the post count. Post-hole concrete is the companion pour.
Whole posts, rails, pickets and bags
Lumber and bags are purchased whole. Leave waste visible for cut pickets, slope adjustments and damaged stock.
- Gates, hardware, stain and rail caps are separate lines.
- Confirm post length for frost or local embedment independently.
- Replace bag yield with the selected concrete product.
Planning boundary
These tools estimate a fence material list. They do not set post embedment, wind design, property-line location or a permitted height.
