Conversion guide · Updated 2026
One tennis court becomes
four pickleball courts or one padel court
A tennis court conversion turns a 78 by 36 foot tennis court on its 120 by 60 foot slab into four pickleball courts for $8,000 to $15,000, one padel court for $30,000 to $55,000, or a multi-sport court with overlapping lines for $6,000 to $12,000. The slab is the asset. If it is sound, the conversion is a surfacing job; if it is not, it is a rebuild with a different set of lines.
Thousands of US tennis courts are converting each year because the slab under them is worth more than the tennis being played on top.

How do four pickleball courts fit on a tennis court?
Two by two, with each pickleball court's long axis running across the tennis court. Four 44 by 20 foot courts with 30 by 60 foot minimum playing areas use the full 120 by 60 foot tennis footprint, with the tennis net line becoming the shared boundary between the two rows.
On a 120 by 60 foot slab the layout is comfortable. On the older 110 by 56 foot minimum, four courts still fit at the 30 by 60 minimum playing area but with no spare run-off. Two courts with the full 34 by 64 recommended area fit on any tennis court with room left for a seating strip.
How much does a tennis court to pickleball conversion cost?
$8,000 to $15,000 for four permanent courts on a sound slab: crack repair, a full acrylic resurfacing in two colors, four sets of lines, four net systems with posts in cored sleeves, and interior fence dividers. Adding pickleball lines to a tennis court that stays in tennis use is $1,500 to $4,000 for two blended courts and portable nets.
| Option | Courts | Low | High | Notes |
|---|---|---|---|---|
| Blended lines, tennis stays | 2 | $1,500 | $4,000 | Contrasting-color pickleball lines; portable nets |
| Full conversion, portable nets | 4 | $6,000 | $10,000 | Resurface, lines, 4 portable net systems |
| Full conversion, permanent nets | 4 | $8,000 | $15,000 | Plus cored post sleeves and interior dividers |
| Full conversion, 2 courts, recommended area | 2 | $6,000 | $12,000 | 34 × 64 ft each with seating strip |
| Conversion plus crack membrane | 4 | $15,000 | $30,000 | Where structural cracks reopen each year |
| Rebuild slab and build 4 new courts | 4 | $80,000 | $140,000 | When the base has failed; see pickleball court cost |
The resurfacing is the same job as tennis court resurfacing, which is why a court that is due for resurfacing anyway converts almost for free. The costs on top are nets, lines and dividers.
Can a tennis court be converted to padel?
Yes, and it is the cheapest way to a padel court. One 20 by 10 meter padel court fits on a tennis slab with room to spare, the slab is checked for flatness and thickness, 18 post footings are cored through it, and the kit goes up. $30,000 to $55,000 where the slab is sound, against $40,000 to $75,000 for a new build.
The checks that matter: the slab must be at least 15 cm thick (a core sample confirms it), flat to 3 mm over 3 meters across the court area, and free of structural cracks in the footprint. Asphalt tennis courts are the exception; padel needs concrete footings, so an asphalt slab gets new footings poured through it and the court is set on those.
A tennis court converts to one padel court plus two pickleball courts with room for a seating area, which is the layout many clubs are choosing. See padel court cost and how to build a padel court.
How do you know if the slab can be converted?
Flood it, drain it for an hour and mark what is left. Birdbaths under a quarter inch are a leveling job inside the resurfacing budget. Deeper ones, cracks you can fit a coin into, or any heave you can feel underfoot mean the base has moved, and a conversion on top of it lasts one or two seasons.
Age is a weak guide. A 30 year old post-tension court in a dry climate converts perfectly; a 12 year old asphalt court on clay soil may not. A contractor who does both resurfacing and construction will tell you which you have; one who only does surfacing has a reason to say the slab is fine.
Fence and lights almost always stay. A 10 foot tennis fence is more than pickleball needs, and tennis lighting on 20 to 30 foot poles covers four pickleball courts well. Interior dividers between courts are the one addition, at $1,500 to $4,000 for a four-court layout.
What about a multi-sport conversion?
A tennis court can carry tennis lines, two or four pickleball courts in a second color and a basketball key at one end for $6,000 to $12,000 in surfacing and lines. It is the right answer for a school, a park or a family that wants all three and the wrong answer for a club, because blended lines slow play and confuse beginners.
Line color convention for blended courts: tennis white, pickleball in a contrasting color such as blue or yellow, and the lowest-priority sport in the lightest shade. Portable nets for pickleball on a shared court cost $150 to $700 per net and store in a shed. See backyard sport court for the multi-sport layouts that start from a blank slab.
