How to use this tool

Measure the complete straight run, including the first and last post widths.
Enter the clear panel span and post width. Run the tool and review the final cut panel and new post count.

Things to know

One straight run, up to 1,000 panels. Corners, gates, slopes, overlap into post slots and installation clearances need separate measurement.
If the final panel would have no positive span after adding a post, the tool reports that the chosen layout cannot fit. Confirm that your panel can be cut to the displayed width.
