The standard height for a split rail fence is three or four feet. This height requires two to three horizontal rails, making it ideal for homeowners wanting a budget-friendly split rail fence. If you’re hoping to contain agile livestock or animals like dogs, geese, or goats, you may prefer to install a six-foot tall fence with four or five rails or a four-foot-tall fence with three horizontal rails. This will help prevent animals from climbing, crawling, or jumping through the rails.

Many types of farm fencing can work well for your farm, but it depends on the type of animal you need to contain and the size of your property. If you want something quick and temporary, go with a metal T-post fence. If you need something that will last forever, go with a synthetic fence made of composite material or PVC. Electric and barbed wire fences are often chosen for docile livestock, like pigs and cows. 

A high-quality wrought iron fence is one of the most durable options available and can last a lifetime, or even centuries, with proper care. However, wrought iron is susceptible to rust and corrosion if not maintained.

To maximize its lifespan, regular maintenance is required. This includes:

• Cleaning the fence with soapy water every six months.

• Scrubbing away any rust or corrosion as soon as it appears.

• Applying a new coat of paint or refinishing the fence every few years to protect the metal from moisture and oxygen. The recommended frequency varies, with sources suggesting anywhere from every 1 to 10 years.

If significant rust develops, it's wise to hire a professional fence repair company to clean the rust and reseal the fence. The cost to refinish a fence is typically between $5 and $12 per square foot, a worthwhile investment to ensure its longevity.

A chain-link fence does not lower your property value. However, chain links are not the most attractive materials—so it probably won’t raise the value either. If this is a concern, opt for wooden posts to provide visual flair and go with a color coating on your fence. Putting in a functional and attractive gate also helps up your resale value when installing a chain-link fence.
