Measure the run.
Mark every post.

Turn a straight fence run into panels, posts, caps, gates, setting materials and a visible reminder that frost depth is local—not a number a calculator should invent.

Gates come out before panels go in

Gate openings do not consume fence panels. Their total width is removed from the run first; only the remaining distance is divided by the chosen panel width. A partial panel rounds up because it must be bought before it can be trimmed.

Posts follow the connection points

One straight run needs a post at each end and between panels. Each gate adds its second gate-side post. The schedule uses the manufacturer’s rule: panels plus one, then one more post per gate.

Local depth unlocks the buried materials

Post concrete and stock length depend on hole depth. Until frost, wind and local requirements are confirmed, both stay marked open. Once depth is entered, concrete is calculated from the hole cylinder minus the actual post section.

Questions before the first hole

How does the calculator count fence panels?

It subtracts the total gate-opening width from the straight run, divides the remainder by the selected 6 ft or 8 ft panel width, and rounds a partial panel up for field trimming.

How many fence posts do I need?

For one straight run, the verified manufacturer method uses one more post than panels, plus one additional post for each gate. Corners and separate runs should be laid out independently.

Why does post-hole depth say confirm?

Frost, wind exposure and local rules can change the required depth. The calculator will not guess a local number. Enter the verified depth to unlock concrete-bag and post-stock quantities.

Does the list include post-setting materials?

Yes. The complete result includes panel and gate items, post caps, a 6 inch gravel base, concrete when depth is known, and reminders for layout and compatible fasteners.
