The table tennis net assembly
The net, its posts and its suspension — the one height that governs both the net and the posts, and why that number appears twice in the Laws.
Overview
The net assembly consists of the net, its suspension and the supporting posts, including the clamps that attach them to the table. It divides the playing surface into two equal courts.
The height is 15.25 cm — and it appears twice. The net is suspended by a cord attached at each end to an upright post 15.25 cm high, and the top of the net along its whole length is 15.25 cm above the playing surface.
The posts sit outside the table
The outside limits of the post are 15.25 cm outside the side line. The same figure again — the net is as far outside the table on each side as it is tall.
That overhang matters in play. A ball that passes outside the net post but still lands on the opponent's court is a good return, because the Laws require the ball to pass over or around the net assembly rather than through it.
No gaps at the bottom or the ends
The bottom of the net, along its whole length, must be as close as possible to the playing surface, and the ends of the net must be attached to the supporting posts from top to bottom.
A ball that passes through the net, or between the net and the post, or between the net and the playing surface, loses the point for the player who hit it. The no-gaps requirement is what makes that rule enforceable.
