A backyard court brings the game home, but courts take more space than the lines suggest. Players need room to run beyond the lines, and the base under the surface is a big part of the cost. This calculator gives the overall area, the base volume, the fence length and a budget.
Overall size, not just the lines
| Court | Playing lines | Recommended overall |
|---|---|---|
| Pickleball | 20 × 44 ft | about 30 × 60 ft (34 × 64 ft for tournaments) |
| Tennis | 36 × 78 ft (doubles) | about 60 × 120 ft |
| Basketball half court | varies | 30 × 30 ft for a backyard |
The extra space around the lines, called run-off, lets players chase wide and deep shots safely. If space is tight, a pickleball court can work with a little less, but not under about 25 × 54 ft.
The base
Most hard courts are built on a concrete slab or asphalt over a compacted gravel base:
- concrete slabs are usually about 4 in thick, reinforced, over 4 to 6 in of compacted gravel;
- post-tensioned concrete resists cracking on large courts like tennis;
- asphalt is cheaper up front but cracks more over time.
slab volume = area × thickness ÷ 12 ÷ 27 (cubic yards)
A 30 × 60 ft pickleball court at 4 in needs 1,800 × 4 ÷ 12 ÷ 27 = 22.2 cubic yards of concrete. Order 5 to 10% extra. The surface needs a slight slope, often about 1%, to shed water, and an acrylic sport coating gives the color and grip.
Fencing
A fence keeps balls in and protects windows and neighbors. The perimeter of a 30 × 60 ft court is 180 ft. Pickleball fences are often 4 ft around the sides and 10 ft at the ends; tennis courts typically use 10 ft fences all around.
Cost
Installed costs vary widely by region, base and finish. Concrete courts with an acrylic surface often run about $8 to $15 per sq ft or more, before fencing, lighting and site work. Modular snap-together tiles over an existing slab are a quicker option.
Before you build
- Check zoning setbacks, lot coverage limits and HOA rules; many towns require a permit for a slab or fence.
- Orient outdoor courts roughly north–south so the low sun is not in players’ eyes.
- Consider noise: pickleball’s hard paddles can disturb neighbors, so allow distance or sound-dampening screens.
- Call 811 before excavating.
