What Direction Should A Pergola Face?

There are two major decisions that you must make when setting up your pergola: where to place it, and what direction to face it.

Use Natural Shade to Your Advantage

Like I said, bringing your pergola from one end of your yard to the other won’t change the shadows you’re getting from the rafters, but it could provide some quality natural protection depending on the tree coverage your yard offers. If you’ve got trees in your yard, feel free to use them.

Covering Your Windows

Another benefit of placement could be the use of your pergola to shade parts of your house. This won’t compromise your outdoor space and could keep a room inside from getting overheated due to being exposed to the sun. Proper placement can “kill two birds with one stone” as the rafters could prevent a window from getting sun at an inopportune time.

Finding the Right Pergola for Your Space

Pergolas come in many different shapes, sizes, and materials. It’s important to choose the right combination for your space. Some styles might fit spaces better whereas others might provide better coverage.

The Optimal Space for Your Pergola

When picking out space in your yard where your pergola will sit, it’s important to keep the sizing requirements in mind. Your typical pergola will feature rafters that hang over the edge of your space. These can be anywhere from 18-20 inches further than the box you’re trying to cover.

Final Thoughts

Always remember to keep your rafters facing the optimal direction for sun protection. A north/south orientation is sure to provide you with a cool, protected space for entertainment in the backyard. Don’t let the sun ruin your day, find the perfect direction for your pergola, before you install it!

Use spacers and string lines to set the ripped 2x spacers atop the pergola

You’ll make the 26 slats that provide the shade for this pergola by ripping 16-ft. 2x4s in half along their length. Before you rip them, you’ll cut the 2x4s to length and add a simple decorative chamfer to both ends of 24 slats. That way, you’ll make each crosscut 12 times instead of 24 times.

Calculating Slat Spacing

Let’s say, for example, you are making a pergola with posts 10 ft. on center with joists that are 134-1/2 in. long. If you want the end slats to be 2-1/2 in. in from the end of the joists like the pergola shown here, subtract 5 in. to get 129-1/2 in. You want about 5 in. of space between each slat. One slat at 1-3/4 in. wide plus one 5 in.
