Fence Pickets Calculator
Pickets are the one fence material where guessing wrong hurts twice — too few and the project stalls mid-run, too many and you're stuck with warped leftovers. This fence picket calculator converts your fence's linear footage, picket width, and gap spacing into an exact picket count with a waste allowance, plus 2026 material costs. The default 5.5-in width matches standard "6-inch" pickets (a 1×6 is actually 5.5 in wide), and zero gap gives you a true privacy count.
0 for privacy fences; 2–4 in for a spaced picket look
5% covers warped and split pickets; use 10% if you can't hand-pick boards
Show the math
Total inches = 150.0 × 12 = 1800.0 in
Effective width per picket = 5.5 + 0 gap = 5.50 in
Raw pickets = 1800.0 ÷ 5.50 = 328.0 (rounded up)
With 5% waste = 328.0 × 1.05 = 345.0 pickets (rounded up)
What the numbers mean
The calculator converts your measurements into a practical purchase quantity using a documented coverage or spacing assumption.
Any whole-unit quantity is rounded up so the result does not leave you short during the project.
Use the cost range as a planning baseline and confirm the final quantity, availability, and delivery charge with your local supplier.

Pro tips
- Hand-pick every picket at the store — reject warped, cupped, and knot-heavy boards; that is what the waste factor is really for.
- A 1×6 picket is actually 5.5 in wide; the calculator already uses true widths, so do not "correct" for it.
- Run 2 rails for fences under 5 ft, 3 rails for 6-ft privacy — rails carry the pickets, do not skimp.
- Pre-stain or seal pickets (all sides, including ends) before hanging — it doubles the finish life.
- Set pickets 1–2 in off the ground to keep them out of standing water and soil contact.
- A 150-ft privacy run needs 345 pickets — that is a full pickup bed, so plan delivery or two trips.
Common questions
Frequently asked questions
How many pickets for 150 feet of 6-ft privacy fence?
150 ft = 1,800 in ÷ 5.5 in per picket = 328, plus 5% waste = 345 pickets.
How many pickets with a 2-inch gap?
The effective width becomes 7.5 in: 1,800 ÷ 7.5 = 240, plus 5% waste = 252 pickets.
How many pickets per 8-foot section?
96 in ÷ 5.5 = 17.5 → 18 pickets per 8-ft section for a privacy fence.
What if I use 4-inch pickets?
They are actually 3.5 in wide: 1,800 ÷ 3.5 = 515, plus 5% waste = 541 pickets for 150 ft.
Should I include a waste allowance?
Yes — 5% if you hand-pick boards, 10% if the lumberyard loads for you. Warped and split pickets are normal.
How many rails do I need?
With 3 rails per 8-ft section: ⌈150 ÷ 8⌉ × 3 = 57 eight-ft rails for a 150-ft run.
