I am going to echo what other people are saying on this thread. According to Coloumb's law, which is the formula that determines the strength of the force between two charged particles, as the charges increase, the strength of the attraction will increase. This means that the electrons will be held more tightly in between the nuclei and therefore the bond length will be shorter.
When there is a double bond, the attraction between the two atoms is stronger which pulls them closer together. Triple bonds pull the atoms together even closer because the attraction is stronger than a double bond.
