Example
Run length: 24 meters Panel width: 1.8 meters Post width: 0.1 meters Gate opening: 1 meters Panels: 13 Line posts including ends: 14 Panel-and-post span · meters: 24.8 Remaining fence run excluding gate · meters: 23
Questions & answers
What does Fence Panel Planner calculate?
Estimate full panels and posts along a straight fence run.
Which units should I enter?
Run length uses meters. Panel width uses meters. Post width uses meters. Gate opening uses meters. Convert values to these units before calculating.
Which formula does it use?
Panels = ceiling((run−gate−post width)/(panel width+post width)); corners and gates need separate detailing.
What does the included example show?
Run length: 24 meters; Panel width: 1.8 meters; Post width: 0.1 meters; Gate opening: 1 meters. Result: Panels = 13; Line posts including ends = 14; Panel-and-post span · meters = 24.8; Remaining fence run excluding gate · meters = 23.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
