Is this net regulation size for competitive volleyball?

No. The 6 m span and adjustable height suit casual and recreational play. Regulation indoor and beach courts use a fixed net height and a wider span, so leagues and schools should look at club-grade systems.

Can I use it for badminton or other net games?

Yes. The adjustable height lets you lower or raise the net for badminton and similar games. Check that the height range covers the sport you want before buying.

How many people can play on it?

A 6 m net fits a small recreational court, so it works for teams of two to four per side in casual games. For full six-a-side play you need a wider regulation net.

Does it come with a carry bag and ground stakes?

The listing does not confirm a carry bag or stakes. If you plan to move it to a beach or park, ask the seller what is included in the box.

How stable is it in wind or on soft ground?

Stability depends on anchoring the posts firmly. On grass or sand, use stakes or guy lines and re-tension the net, since a light recreational frame can shift in wind or under hard spikes.
