What Size Gazebo Do You Need?

You have a table in mind, a few chairs, and a yard that looks bigger from the kitchen window than it does with a tape measure in hand. Gazebo sizes are quoted in feet of footprint, but what you really need is room to sit, stand and walk. This page works back from your furniture and guest list to a size that fits.

Start with the table and the people

Begin with what goes under the roof, not the gazebo itself. Count the seats you want on a normal day, then the extra chairs for a party. A round or square table for four sits comfortably in a small footprint. A long table for eight to ten needs a long rectangle.

Measure the table and add the chairs pulled out. A chair needs roughly three feet behind it for someone to sit down and stand up. So a table that is 4 feet across becomes about 10 feet across once chairs sit on both sides. That is why a 10' x 10' is a snug fit for a small dining set, and an 8' x 8' suits a bistro table or two lounge chairs.

If you want a long table for a crowd, look at shapes that run in one direction. A 10' x 16' or a 12' x 18' gives you length for a bench table with room at the ends.

Add the walking space

Chairs are only half the story. People need to move around the furniture, to reach a seat, carry a dish or step out. A good rule of thumb is about three feet of clear path along any side people will walk. Along a wall or rail that stays unused, you can get away with less.

Sketch your layout on the lawn with chalk or string, then set the chairs in it. Walk the edges. If you have to turn sideways to pass, the footprint is too small. Adding two feet to the width often fixes it, which can mean stepping up from a 10' x 12' to a 12' x 12'.

Think about shape

Shape changes how much of the floor you can actually use. A rectangle suits a straight table and fits against a house or fence line. An octagon puts the middle of the floor to good use, so it suits a round table with seating all around, but the corners are cut away and long furniture won't fit. An oval gives a rectangle's length with softer ends, which is handy if you want the look without sharp corners.

A 14' octagon holds a round table and chairs with room to walk. A rectangle with the same area would hold a longer table.

Go bigger for lounging, grills and crowds

Lounge furniture takes more room than dining chairs. Sofas, a coffee table and a side chair can use as much floor as a ten person dinner. If you want a seating area and a dining area under one roof, look at footprints from 14' x 24' upward. Large ovals and rectangles also suit a yard where the gazebo is the main feature of the garden.

Double roof styles are listed on some of the larger models. Check the product page for what that adds to the look and the cover.

For big gatherings, the largest ovals and rectangles are more like an outdoor room. They need a flat, open site and a bigger budget for the base.

Measure your yard and check setbacks

Mark the footprint on the ground with stakes and string. Then add space around it for a path, for roof overhang, and for people to walk around the outside. The roof is often wider than the floor, so allow for that when you check clearance from a fence, a tree or the house.

Setbacks are the minimum distances your town or neighbourhood wants between a structure and the property line. They vary by place. Call your local planning office or check your homeowners association rules before you order. Also ask whether a gazebo of your size needs a permit.

Choose flat ground where you can. Plan the base, whether that is a slab, deck or pavers, before you finalise the size, because the base should match the footprint.

How to choose

• Work from the table. Add the chairs and a three foot path, and that is your minimum footprint.
• Match shape to furniture: rectangles for long tables, octagons for round ones, ovals for length with softer ends.
• Pick the material that suits your upkeep. The range includes treated pine, cedar and vinyl, so check each product page for care details.
• Measure the yard with the roof overhang in mind, and keep clear of fences and trees.
• Check local setbacks and permit rules before you buy.
• If you are between two sizes, go for the larger one if the yard allows.

Questions people ask

What size gazebo seats six people?

A 12' x 12' or a 10' x 16' is a sensible place to start. It depends on the table shape and whether you want to walk around it.

Is a bigger gazebo always better?

No. A gazebo that crowds the yard or sits too close to a boundary causes more trouble than it solves. Choose the size your furniture and site can handle.

Does the roof count in the measurement?

The size in the name is the footprint. The roof may extend past it, so allow a little extra space around the edges.

Do I need a permit?

It depends where you live. Ask your local planning office, and read the manual for the base and installation.
