A fence needs one post every 8 ft plus one at the end, and one 8-ft panel per span, so 100 ft of straight fence takes about 14 posts and 13 panels.
Posts, panels, concrete, post caps, and gate hardware for any fence run.
Measure all sides of your fence run
8 ft is standard. 6 ft for taller or heavier fences.
Based on the dimensions on the left — edit them to match your project and this updates as you type.
13 panels/sections — subtract for gate openings
Tip: Buy 1-2 extra panels. Damaged panels happen during installation.
14 posts — extra 2 ft for burial depth
Tip: Posts should be buried 1/3 of their total length. A 6 ft fence needs posts buried 2+ ft.
28 bags — 2 bags per post
Tip: Dry-pour method works great for fence posts — pour dry mix, add water, tamp. No mixing required.
Keeps water out of end grain — significantly extends post life
Galvanized or coated only — never use plain steel with PT lumber
Manual digger for 6 posts or fewer — rent a gas auger for more
Tip: Rent a 2-person gas auger from HD for $60/day if you have more than 8 posts to dig.
Keep your top rails perfectly level across the run
Don't forget
Check your local zoning rules before you start. Fence height limits (typically 4 ft front yard, 6 ft backyard) and permit requirements vary by city. Call 811 before digging.
