How the calculation works
The formulas
Gate positions are distances from each run’s start. Panel spans on either side round up independently; gate ends are posts. Separate runs retain all endpoints, a connected chain shares one post per join, or you can enter a verified shared-corner count.
Panels per solid span = ceil(span length ÷ effective panel width)
Posts before sharing per run = panels + gates + 1
Final posts = Σ(run posts) − shared corner posts
Assumptions to check
- Panel width is the effective post-to-post module, including the installation’s connection allowance.
- Post strength, foundations, terrain slopes, and gate hardware are outside this quantity model.
A worked example
A 10 m run with 2 m panels and no gate needs 5 panels and 6 posts. Two such runs sharing one corner need 10 panels and 11 posts.
