Quick answer: the rules are identical, but the balls are not. Outdoor balls are harder and slightly heavier with about 40 small holes, so they fly straighter in wind and play faster. Indoor balls are softer and lighter with about 26 larger holes, so they play slower and are easier to control on a gym floor. Use the ball made for your surface: an outdoor ball skids on wood, and an indoor ball gets blown around and wears out quickly outside.
Walk from a community-centre gym to a park court and you will notice it within three shots: the ball sounds different, bounces differently, and your dinks that floated nicely inside suddenly sit up or die in the net. Nothing about the rules has changed. Everything about the ball and the surface has.
| Outdoor ball | Indoor ball | |
|---|---|---|
| Holes | About 40, small | About 26, larger |
| Plastic | Harder, thinner wall | Softer, more flexible |
| Weight | Slightly heavier | Slightly lighter |
| Speed | Faster, skids through | Slower, sits up more |
| Wind | Holds its line better | Blown around easily |
| Durability | Can crack, especially in cold weather | Lasts longer, but goes soft |
Every approved ball, indoor or outdoor, has to fall within the same official limits for size, weight and bounce, which is why the rules do not change. The differences are in how the plastic and the hole pattern behave in the air and off the surface. Outdoor balls such as the Franklin X-40 and Dura Fast 40 are the common tournament balls outside; indoor balls are designed with fewer, larger holes for the slower, grippier gym game. Most groups have a house ball, so ask before you buy a tube.
Indoors you are usually on a wooden or sport-tile gym floor, with pickleball lines taped or painted over basketball and badminton markings. That is the first thing to get used to: lots of extra lines, and the pickleball ones are the ones that matter. Floors are consistent, there is no wind, and the light is even, but ceilings can be low enough to limit lobs and the bounce can be lower on a slick floor. See court dimensions for the lines you need to find.
Outdoors you are usually on an acrylic-coated hard court, either a dedicated pickleball court or lines added to a tennis court. The surface is grittier, the ball bounces higher and faster, and you deal with wind, sun and temperature. Cold makes outdoor balls harder and more likely to crack; heat makes them a little livelier.
Whichever you play, the shape of the point is the same: serve deep, return deep, get to the kitchen line, and win the soft game. You can practise that pattern any time in the free online pickleball game here.
