# Is a given time control per side or in total?

The Wikipedia page about Chess Time Control describes for example:

... 90 minutes for the first 40 moves ...

A move in chess is defined as both White and Black side doing their separate move, so if the 90 minutes are per side, then the Wikipedia description appears to be misleading.

This applies also to the World Chess Championship 2018.

Are these 90 minutes per side, or total ?

• I don't see what's misleading about it. White makes 40 moves. Black makes 40 moves. Each of those actions must be performed using less than 90 minutes. It would be rather silly for the time control to be total. In that case, white could spend 89:59 making their move, and black would have just one second to make theirs.

• The part I found misleading is that a move in chess is defined as both White and Black side doing their separate moves, so a move is actually defined as two "half" moves by both White and Black side. Commented Dec 4, 2018 at 9:31
