Why are panels rounded up?

Fence panels are bought as whole sections, so any partial remainder is rounded up to the next full panel.

What happens if total gate width is 0?

The calculator treats the layout as a no-gate fence, even if the gate count field is still above 0.

Why might a contractor’s post count differ?

Installers do not all space panels, frame gates, or handle corners the same way. This tool follows simple section math from your dimensions only.

Does this tell me footing depth or code requirements?

No. It is a buying estimate for panels and posts, not a permit, structural, or code-compliance plan.

Should I add extra panels or posts?

Add any buffer yourself if you want one. This calculator does not bake in a spare-panel or extra-post allowance.

How It Works

Formula

G = \begin{cases} R & \text{straight run} \\ 2(L + W) & \text{rectangular yard} \end{cases}

N = G - W_g

P = \left\lceil \frac{N}{W_p} \right\rceil

S = P + g

T = \begin{cases} S + 1 & \text{straight run} \\ S & \text{rectangular yard} \end{cases}
