Push the rim sections into a circle, fit a leg at every joint, flip it over, hook the net on at four opposite points and then tighten it evenly. The whole thing takes two minutes. The tension is the only part that is easy to get wrong, and it decides whether the game is any fun.
Here is the test almost nobody knows about: drop a ball onto the middle of the net from 1.5 m. It should bounce back around 50 cm. That number is not mine. It is in the International Roundnet Federation rulebook, and it is the difference between a net that plays and a net that sulks.

Every set on the market is built the same way, whoever made it. A rim that comes apart into curved segments, one leg for every joint in that rim, and a net that hooks onto the rim all the way round. Plus a ball, usually two. That is the whole inventory. Lay it out and count it.
"So if I only got one bag of parts, is something missing, Jakub?" Probably not. Lay it out on the grass and count: segments, the same number of legs, one net. If those three match, you have a complete set. Pumps and spare balls vary by manufacturer and by price bracket, and a missing pump is an annoyance rather than a problem, since any ball pump with a needle works.
A regulation set is 91.4 cm across at the top, which is 36 inches, and 20.3 cm high. Roughly ankle height, roughly a metre wide. If yours is noticeably smaller, you have a travel or junior version, which is fine to learn on and will feel different from the sets used at tournaments.
That is it. You can play immediately. If you want the game itself explained before your first rally, that is over on what is roundnet.
Tension. And it is not a matter of taste, there is a written standard for it.
The IRF rules say the tension should be consistent throughout, and they define it with a drop test: a ball released from 1.5 m above the ground should bounce 50 cm off the net, measured from the bottom of the ball. Two people, one dropping and one crouching at eye level to watch. Ten seconds and you know.
Drum skin, not hammock. A loose net swallows the ball, kills every rally on the second touch and teaches beginners that they are bad at a game they have simply set up wrong. An overtightened net does the opposite: the ball rockets off at angles nobody can read, and the frame and the net both wear out faster.
One more thing that costs nothing: check the tension again after twenty minutes of play. Nets settle, especially new ones and especially in the heat.
Two causes. I have never seen a third. Either a leg was never pushed fully home, or the net is uneven and is pulling the circle out of shape. Uneven tension turns a circle into a slight oval, and an oval frame has one weak joint that gives up first.
The fix for both is the same: take the tension off, reseat every leg, hook the net back on in opposite pairs, tighten evenly. Ninety seconds of work. It saves you the afternoon.
On sand there is a third symptom that looks like a broken set but is not: the legs sink, the rim ends up sitting lower on one side, and suddenly the ball behaves strangely. That is the ground moving, not the set failing. Stamp the sand flat, or move a metre and start again.
Release the tension first. Always. A net stored under load stretches, and a stretched net never comes back. That is the single most common way a set gets ruined, and it happens slowly enough that nobody notices the cause.
After that: unhook the net, pull the legs, break the rim into segments, bag it. Sand and grit in the joints is what makes a rim stiff over a season, so a quick shake before it goes in the bag is worth more than any cleaning you will do later.
A ball dropped from 1.5 m should bounce back about 50 cm, measured from the bottom of the ball, and the tension should feel the same everywhere on the net. That is the standard in the IRF rules.
Two to three minutes the first time, under a minute after that. Slow down on the tension, rush the rest if you like.
Hardware down, smooth surface up. Any printing on the net is meant to be read from above.
91.4 cm across at the top and 20.3 cm high, per the IRF rules. About a metre wide, about ankle height.
Usually not. Either the legs were not pushed fully in, or the net is tighter on one side and is pulling the frame oval. Reseat everything and tighten in opposite pairs.
Yes, every time. Storing a net under tension stretches it permanently, and that is how good sets quietly go bad.
Yes, sports halls are a normal venue and a lot of winter play happens indoors. What limits you is ceiling height and the space around the net, not the floor.
Set it up, drop a ball on it, and watch how it comes back. If the bounce looks dead, you have just found the reason your last game was frustrating, and it was never you.
