Estimate fence length, posts, panels, pickets, and extra material for wood, vinyl, chain link, and metal fencing projects.
Panel formula:
Fence length ÷ panel width = number of panels
Post formula:
Panels + 1 = posts needed
For wood fences, this calculator also estimates picket count using picket width and gap spacing.
Knowing how much fencing material you need helps when planning privacy fences, yard enclosures, and property lines so you can order enough material before installation begins.
Extra material is often useful for waste, bad cuts, damaged pickets, and future repairs.
Your result shows the estimated number of fence panels, posts, and pickets needed based on the length, spacing, and material inputs entered. The estimate also includes a waste allowance.
Actual fence needs can vary depending on corners, end posts, gates, terrain changes, and local installation practices. Always compare the result with your final fence layout before ordering materials.
Divide the total fence length by the spacing between posts to estimate the number of sections, then add one more post for the end.
Use the fence length and divide it by the effective picket coverage, which is the picket width plus the gap between pickets.
Yes. Gates affect layout and material planning, especially when counting posts and total fence sections.
Many projects use around 5% to 10% extra for waste, cuts, breakage, and future repairs.
