Picket fences are a well known style of decorative landscape fencing, meant to enhance a flower garden and small lawn. They are best suited to smaller yards due to their smaller scale, and there are many designs to choose from. Another type, low decorative metal fences, usually set on top of a low masonry base, or strung from footing to footing, are also suited to small residential use.
Solid panel fences are appropriate for any application, depending on their height. Lower ones, sometimes as low as a foot or two, can be used as decorative landscaping borders, waist height ones to define public spaces (such as a front yard or patio), and tall ones are ideal privacy fences.
Chain or other non-decorative metal fencing is most often purely functional, intended as a security fence. It is rarely used in a decorative way due to its simple appearance and strong association with industrial or security purposes. It is unsuited to residential settings for this reason, except for use in pet enclosures inside attractively fenced yards.
