Asphalt Tennis Court: Size, Slope, Thickness, Coatings and Tons of Asphalt

An asphalt tennis court is a hot mix surface built on a compacted stone base, sloped in a single plane for drainage, then finished with an acrylic color coating system that provides the playing texture, color and lines. It's the most common hard court type in the U.S. because it costs less than post-tensioned concrete. A standard doubles court is 36 by 78 feet, but the paved area is much larger, commonly around 60 by 120 feet for a single court, so you're paving about 7,200 square feet. Plan for cracks over time; asphalt courts need periodic crack repair and resurfacing.

Court Size vs Paved Size

The lines of a doubles court measure 36 by 78 feet. Players need room behind the baselines and beside the sidelines, so the fenced and paved area is bigger. Commonly recommended overall dimensions for one court are about 60 by 120 feet; some backyard courts go smaller to fit a lot, at the cost of run-back room. Multiple side-by-side courts share space between them.

Layout	Approximate paved area	Square feet
Single court, full recommended size	60 × 120 ft	7,200
Single court, compact backyard	56 × 114 ft	6,384
Two courts side by side	108 × 120 ft	12,960

Check any dimensions against current guidance from court builders' associations and your local zoning setbacks before you design.

Slope for Drainage

Tennis courts are sloped in one flat plane, from one side to the other, one end to the other, or corner to corner, rather than crowned like a driveway. A slope of around 1 percent (roughly an inch in 8 to 10 feet) is commonly used. Too flat and water sits in "birdbaths"; too steep and the ball and footing are affected. Our slope calculator converts inches of fall to percent.

Base and Asphalt Thickness

A typical build removes topsoil, compacts the subgrade, and places several inches of compacted crushed stone, often 4 to 8 inches depending on soil and frost. The asphalt is usually laid in two lifts, a binder course and a finer surface course, for a total of roughly 2 to 3 inches. The surface course needs to be very smooth, since small dips hold water and show through color coatings. Our post on basketball court thickness covers a similar build for smaller courts.

Tonnage Example

For a 60 by 120 foot court at 2.5 inches of compacted asphalt:

• Area: 7,200 square feet
• Volume: 7,200 × 2.5 ÷ 12 = 1,500 cubic feet
• Weight: 1,500 × 145 pounds per cubic foot ≈ 217,500 pounds
• Tons: about 109 tons

Split it by lift if you need separate orders for binder and surface mix. Use the asphalt tonnage calculator with your own dimensions.

Curing Before Color Coats

New asphalt needs time to cure before acrylic coatings go on, so oils in the fresh binder don't interfere with bonding. Coating manufacturers commonly call for at least a couple of weeks, and many court builders prefer about a month. Before coating, the court is flooded or checked after rain to find low spots, which are patched with an acrylic patch binder.

The Acrylic Color System

Most hard courts use several layers: an acrylic resurfacer to fill surface texture, then two or more color coats with sand to set the playing speed, then line paint. The number of coats and the sand content affect how fast or slow the court plays. This is specialized work, and a manufacturer's certified installer is usually the best choice.

Cracks and Resurfacing

Asphalt courts crack as the pavement ages and the ground moves. Hairline cracks are filled when the court is resurfaced; wider cracks may need specialty crack repair systems or fabric membranes, and severe cracking may call for an overlay. Many courts are resurfaced with fresh color coats every several years, depending on use and climate. Keeping water off the court and vegetation away from the edges extends its life.

Fencing, Nets and Lighting

Fence posts, net posts and light poles are set in concrete footings, and the timing matters. Net post sleeves are usually set before the final surface course so the court stays smooth around them. Fencing is commonly about 10 feet high around tennis courts to keep balls in, sometimes lower along the sides near spectator areas. Light poles need wiring run before paving. Planning all of these in advance avoids cutting into new asphalt later.

Common Mistakes on Asphalt Courts

• Skipping soil preparation, which leads to settling and cracks
• Crowning the court like a driveway instead of using a single plane
• Coating too soon after paving
• Letting trees overhang the court, which drops leaves and sends roots under the edges
• Ignoring drainage around the perimeter so water sits against the edges

Everyday Care

• Sweep or blow off leaves and debris, which stain coatings
• Push water off with a court squeegee roller after rain
• Keep bikes, skates and furniture with narrow legs off the playing surface
• Loosen the tennis net tension in the off-season to reduce strain on posts

Adding Pickleball Lines

Many owners add pickleball lines to a tennis court in a contrasting color. Four pickleball courts fit in a standard tennis enclosure with the right layout. For trial runs before painting, court marking tape lets you test the layout. See our asphalt pickleball court guide for sizes and slopes.

Bottom Line on Asphalt Tennis Courts

An asphalt tennis court is a smooth, single-plane hot mix slab on a solid stone base, cured and then finished with acrylic color coats. Expect to pave around 7,200 square feet for one full-size court, about 109 tons at 2.5 inches. Get the slope and smoothness right, wait before coating, and plan on crack repair and resurfacing as part of owning it.
