Half court basketball: sizes and building costs
A regulation half court is half of a full court: 47 by 50 feet for NBA and college, 42 by 50 feet for high school. At home, most people build smaller, from 30 by 30 feet to 30 by 50 feet, which keeps the free-throw lane and most of the three-point arc. A 30 by 50 foot half court typically costs $10,500 to $24,000 installed with an acrylic finish, or $16,500 to $28,500 with sport tiles.

Why most home courts are half courts
- One hoop is enough for shooting, one-on-one and small games.
- A half court fits most suburban backyards where a full court never could.
- It costs roughly half as much as a full court in concrete and surface.
- You can still mark a full-size key and a high school three-point arc.
- The spare width takes a second game, such as pickleball or four square.

What a good quote includes
Ask for these six points in writing. Two quotes that cover them can be compared line by line.
Width first
Full width is 50 feet. A narrower court still works if the key is centered and the arc is shortened at the sides.
Depth
Depth from the baseline sets how much of the arc fits. About 28 to 30 feet takes a high school arc at 19 feet 9 inches.
Which arc
High school 19 feet 9 inches, college 22 feet 1.7 inches, or NBA 23 feet 9 inches. Pick the one your players use.
Lane width
High school and college lanes are 12 feet wide; the NBA lane is 16 feet.
Hoop overhang
The backboard face sits about 4 feet inside the baseline, so the pole is behind the court, not on it.
Clear space
A few feet beyond the lines on every side, more behind the hoop where players land.

Set the size
You and the builder fix the width, depth and which three-point arc to mark.
Groundwork
The area is excavated, graded to a single gentle fall and given a compacted base.
Slab and surface
A reinforced concrete slab is poured, cured and then coated or tiled.
Lines and hoop
The lane, free-throw line and arc are marked from the hoop position, then the hoop is set.
Questions people ask
What are the dimensions of a half court?
A regulation half court is 47 by 50 feet (NBA and college) or 42 by 50 feet (high school, half of 84 by 50). Home half courts are often 30 by 30 to 30 by 50 feet. VersaCourt sells kits from about 28 by 44 feet to 31 by 59 feet.
How much does it cost to build a half court?
HomeAdvisor says $8,600 to $40,000 for a 47 by 50 foot half court. A 30 by 50 foot court with an acrylic finish works out at about $10,500 to $24,000, before a hoop or lights.
Can a half court have a full three-point line?
Only if it is deep and wide enough. A high school arc at 19 feet 9 inches fits a court about 30 feet deep and 42 to 50 feet wide. The NBA arc needs the full 50 foot width and about 30 feet of depth.
How much concrete does a half court need?
A 30 by 50 foot slab at 4 inches thick is about 500 cubic feet, roughly 18.5 cubic yards, before allowing for waste and thickened edges. Your builder will work out the exact order.
Is a half court big enough for games?
Yes for shooting, one-on-one, two-on-two and three-on-three, which is the format FIBA plays on a half court. Five-a-side needs a full court.
