In order to be sure that you want to build a pergola, you’ll want to be able to identify the other similar outdoor structures to remove any potential confusion.
What is the difference between a gazebo, arbor, pergola, and trellis?
As you look into improving your yard spaces, you will see these terms floating around all over and it is very easy to mistake one for the other. Frequently, the images you find on websites as you search for info will classify them incorrectly because of how easy it is to mix them up! However, they are all unique structures that you can clearly identify with a few hints.
It is important to know what you want and how you want to use it determine which structure you want to build.
The following descriptions will show you that not only do some key physical characteristics differentiate between the four structures, but so does their overall purpose or use in the yard.
Trellis – Primarily used to support plants
A trellis can be standalone or it can be a part of an arbor, pergola, or gazebo wall. The basic definition of a trellis is that it is a wall piece that supports growing vines. It is usually just a one sided piece with lattice work that is perfect for vines to grow around. They are frequently not permanently placed in the ground and don’t have any type of roof that provides shade or shelter.
Arbors – Gateways to outdoor spaces
Arbors are primarily used to cover entrance ways or gateways, usually into a back yard from the front or to delineate two distinct garden areas. They traditionally have an arched top, and it is customary to have vines growing up them. This is where a trellis is sometimes part of an arbor as there can be latticework between the walls of the arbor. An arbor is also typically not large enough to cover a patio area. The ‘walls’ are more like side panels that are often barely a foot or two wide.
Gazebos are almost complete outdoor rooms in a yard or on a deck. Typically set at the outer edge of a yard, particularly to capture available views. They are large enough to hold seating for many people and often even have bench seats built into the walls. They are either round or polygon in shape. Rather than having posts as the anchors into the ground, gazebos are built with a fully complete raised floor and rather sturdy foundation. This is necessary because the other main feature that sets a gazebo apart is the complete roof cover. The only part of a gazebo that is left open is usually the upper walls. Otherwise, a gazebo really could be a shelter from a storm. Due to it’s heavier duty nature, gazebos are a bit expensive to build and almost surely require a permit.
Pergolas – the best of them all for shade and character
A pergola combines the best parts of the other structures, then adds a splash of ambiance and character to them. Pergolas are defined as a structure secured into the ground with posts of columns. They can be attached to a house on one side or they can be free standing. They don’t have the full roof of a gazebo, but instead provide plenty of shade through a dappled pattern of beams and rafters. The edges of the roof pieces are given a fancy cut to add flare to the design. Here are a couple of basic examples:

Putting The Parts Together
Trellis corners can be added around posts, the roof of a pergola can be curved like an arbor, and the pergola can provide shade cover for a patio or deck like a gazebo. The best thing is that while a pergola can combine aspects of all three, it is very easy and inexpensive to build.
