How Big Is a Backyard Basketball Court?

Want a basketball court at home? First, you need to know if it will fit. Courts come in many sizes. This guide covers common sizes and how to check your yard.

Full Court Sizes

A full NBA court is 94 feet long and 50 feet wide. Many older high school gyms are 84 feet long, and some are even 74 feet (Wikipedia: Basketball court).

A full court takes a lot of space. Most backyards can't fit one. But some big lots, churches, and schools can.

Half Court Sizes

A half court is the most popular choice for homes. Half courts come in many sizes. Here are some common ones:

• Residential half court: about 30 by 30 feet
• Junior high half court: about 37 by 42 feet
• High school half court: about 42 by 50 feet
• NBA half court: about 47 by 50 feet

A smaller court is fine for shooting and games like HORSE. A bigger court gives more room for full games.

Don't Forget Extra Room

Players run past the lines. They chase loose balls. So it helps to have some open space around the court. A fence can also help keep balls in your yard.

How much extra room you need depends on your yard and how you play. Ask our crew what we suggest.

Where Does the Hoop Go?

The hoop usually sits at one end of the court. In-ground hoops need a strong footing. Our crew will plan for that when they pour the slab.

Think about the sun too. Shooting into a low sun is hard. Ask our crew which way the court should face on your lot.

How to Measure Your Yard

You can do a quick check today:

• Pick the flattest open spot.
• Mark the corners with stakes or cones.
• Measure the length and width with a tape measure.
• Look for trees, slopes, wet spots, and septic or utility lines.
• Make sure trucks can reach the spot.

Then take photos. They help our crew plan.

Other Things That Change the Size

Your court size is not just about the lines. Think about these too:

• Fences: A fence needs its own space at the edges.
• Seating: A bench or two gives players a place to rest.
• Lights: Light poles take up room near the court.
• Paths: Plan a safe way to walk from the house to the court.
• Future plans: Want pickleball lines later? A bigger slab now can make that easier.

Write down what you want. Then share the list with our crew.

What Does It Cost?
