Equal slat & panel spacing

MEASURE FIRST

How to prepare your inputs

Measure the fence alignment from verified boundaries and plans. Price comparable heights, materials, gates and removal.

How this calculation works

With equal gaps at both ends, gap = (span − count × width) ÷ (count + 1). Centre pitch = width + gap.

Assumptions & exclusions

No balustrade, pool-barrier or child-safety compliance assessment. Clear span excludes end supports. Check actual widths, end-gap arrangement and approved spacing.

Your next step

Confirm boundary position, neighbour arrangements, post design and local requirements before work.

What if my shape or product is different?

Use dimensions and product data that match the stated method. For complex work, calculate separate sections or obtain a project-specific take-off. Do not apply simple geometry to structural or compliance decisions.

Why are quantities rounded up?

Whole bags, packs, sheets or cartridges round up to purchasable units. Decimal area or volume results are planning figures; confirm order increments with the supplier.
