Cantilever Gate Calculator for Farm Entrances

🐄 Cantilever Gate Calculator

Estimate leaf length, counterbalance, steel weight, and footing concrete for farm entrances and yard openings

🧰Gate Setup

Unit system

Gate outline

Gate material

Counterbalance ratio

Rougher ground means closer post spacing.

Frame depth

Use the actual number of corners or turns.

Footing diameter

Each gate opening adds two gate posts.

Opening width (ft)

Overage buffer

Use a buffer for cuts, corners, and laps.

Length (ft)

Width (ft)

Diameter (ft)

Brace count

Used to estimate post spacing around the curve.

Base (ft)

Height (ft)

Custom area (ft)

Footing depth

Use the number of straight fence runs.

📊Gate Build Comparison

Galvanized steel

16 ft spacing

Best for: wide openings and farm lanes.

Shape: simple, durable, and common on open pasture.

Containment: solid when cattle are trained.

Aluminum tube

18 ft spacing

Best for: lighter leaves with clean lines.

Shape: fewer points, cleaner appearance, easy to inspect.

Containment: works well with trained cattle.

Mesh Gate

12 ft spacing

Best for: rigid leaves with airflow.

Shape: closer posts, tighter mesh, more stability.

Containment: strong on small livestock pressure.

Pipe Gate

8-10 ft spacing

Best for: stronger gate leaves and posts.

Shape: rigid rail layout with strong corner support.

Containment: ideal near handling areas.

🧰How the Build Breaks Out

Tip: Put gates on straight runs when you can. That keeps steel stock simple and makes the gate or rail layout easier to measure.

Tip: On rough or rolling ground, shorten post spacing before you stretch the gate. It helps control sag and keeps the gate line more uniform.

A cantilever gate is a type of sliding gate that is supported by a single cantilevered arm. The gate is suspended from the top of the post, so the track dont touch the ground. The gate moves along a track, but the track is hidden from view.

Cantilever gates is ideal for uneven terrain because the track isnt visible on the ground. Many people chooses cantilever gates for there privacy. The gate can be installed by a professional to ensure its works perfecty.

What Is a Cantilever Gate

The gate cant be damaged by snow or debris because the track is hidden. However, the gate require more space for its operation than a standard sliding gate. You should of measured the space before you buys one.

The weight of the gate will be supported by the cantilever arm. If you are building a fence, the gate should be part of a larger system. A cantilever gate can handle alot of weight, so it is great for heavy wood or metal gate.

You should make sure the post is strong enough to hold the weight, otherwise the gate will sag. Its important to pick the right size for your yard.
