Fence picket light spacing
Estimate light feet (or stake/clip count) when wrapping fence pickets from picket count, wrap turns, and bulb/clip spacing.
light_ft = pickets × turns × (picket_height_ft) · clips ≈ light_ft × 12 ÷ spacing_in
When to use
This tool helps when you want a fence picket light spacing planning figure with the assumptions written down. You will enter picket count, wrap turns per picket, picket height (feet), and optional clip/bulb spacing (inches).
For vertical picket wraps, each turn roughly covers the picket height once if you spiral loosely — enter turns as how many up/down passes you want per board.
Stop and ask a licensed electrician when loads, hardwired outlets, or roof work go beyond temporary plug-in holiday displays.
Number of pickets you will wrap or outline.
1 = single pass; 2–3 = denser spiral.
Exposed board height you will wrap.
Used for clip estimate; 0 skips clip count.
Worked example
Example inputs from the form defaults — Picket count = 20; Wrap turns per picket = 2; Picket height (feet) = 5; Clip / bulb spacing (inches) = 12 — are plausible homeowner figures, not a survey of your house.
Compute with: light_ft = pickets × turns × (picket_height_ft) · clips ≈ light_ft × 12 ÷ spacing_in. Show intermediates before the final count or length.
When the calculator and scratch math disagree, fix units first; the fence picket light spacing model is only as good as consistent inputs.
Limits / assumptions
Units: keep every length in one system (feet or inches end-to-end) and every electrical quantity in the units the labels name. Mixing without converting invents a wrong answer.
Where the formula fails: odd geometry, wind on inflatables, worn sockets, and conditions not listed on the page are outside the model. Zero or nonsense inputs should error — do not force a number.
Not a substitute: the fence picket light spacing result is a planning aid for holiday decorating — not an install quote, structural opinion, or product warranty.
Simplifies wrap length as height × turns (not true helix arc). Add spare for rail jumps between pickets.
Do not staple through fence wiring or paint in ways that trap moisture. Use outdoor clips and GFCI protection.
FAQ
Outline instead of wrap?
Set turns ≈ 1 and use height as the vertical run, or switch to a linear eave/strand tool for top-rail only.
Rail jump waste?
Add 0.5–1 ft per picket gap in your head when daisy-chaining across a fence.
Metal vs wood pickets?
Same length math; use magnetic or zip-tie clips rated for outdoor use on metal.
Stake lights along the fence?
Use Pathway light stake count for ground stakes; this tool is for wrapping boards.
