Your home should be the place where you feel the most relaxed, but you might be in need of some privacy fence ideas if your exposed backyard is making it hard to truly unwind. “Privacy fencing, either along a property line or around a specific area in your garden, creates a sense of sanctuary, seclusion, and peacefulness,” says Janice Parker, a landscape architect based in Greenwich, Connecticut. “A garden should, at its best, connect us to nature, and this is simpler to do when you can relax in a peaceful setting. Hidden areas, made with privacy screening, create a sense of mystery, as you do not see all of the garden at once. Mystery makes a great garden!”

Luckily, clever retaining wall ideas and privacy fence ideas (some are even DIY landscaping designs) can ensure your backyard is the secluded oasis you want it to be. “A privacy fence does all the work of a typical fence—indicating boundaries and keeping people and animals in or out—while also blocking views into the yard,” says Kevin Lenhart, a landscape designer and design director at Yardzen, one of the nation’s largest online landscape platforms.

Here, a guide to building backyard landscaping and a privacy fence—whether you use a pergola or a trellis—to keep onlookers out and a peace of mind in.

Are privacy fences a good idea?

“From an ecological and natural point of view, privacy fences are the least desirable element in the landscape,” says Jonathan Fargion, a landscape designer based in New York City. This doesn’t mean privacy fences are necessarily a bad idea, just that there are a few considerations to take into account before getting started.

Privacy fences cut the land into lots, which can be problematic for the bugs, insects, and other wildlife that live there. “As a rule of thumb, fences should be at least two inches off the ground to let critters the freedom to move between properties,” Fargion explains. In general, he says privacy fences make the most sense on small properties, like town house gardens. For larger yards, he suggests making use of natural greenery, like trees, to keep unwanted eyes from infiltrating your space.

How tall can I make my privacy fence?

Fences that are six feet tall should block most views from the ground level. “I’d advise not going any taller than you have to, both to save on expenses and to limit the shrinking, enclosing effect fences can have on a space,” Lenhart says. If you do need extra height, he suggests adding 12 to 18 inches of lattice on the top of a fence, which will add privacy while minimizing the visual impact of a taller fence. If you opt for a natural privacy hedge, these can be much taller and often go up to 12 feet.

What is the best type of privacy fence?

The best privacy fence will depend on each homeowner’s goals for the fence and their yard. “By necessity, privacy fences must obscure sight lines,” Lenhart says. For this reason, many privacy fences are made from solid wood and designed to be completely opaque. If the goal is to have complete seclusion, something solid without any gaps would likely be the best choice.
