Re: Bond Length
To the best of my understanding
Bond length has to be determined experimentally and can vary depending on which atoms are interacting
In terms of decreasing strength it would be triple bond, double bond, single bond
In terms of decreasing length it would be single bond, double bond, triple bond
In resonance structures, a hybrid bond length is observed. If the resonance is between double bonds and single bonds the value of each bond would actually be somewhere between these two bond lengths

or does that depend on the type of bond ?

Yes. Multiple bonds are shorter than single bonds. Adding bonding electrons attract nuclei more and pulls the atoms closer.

Re: Bond Length
You do not need to know how to calculate bond lengths unless the covalent radii are given for each atom (then the bond length is the sum of these radii). It is helpful to know that triple bonds are the shortest, then double bonds, then single bonds, and that triple bonds are the strongest, then double bonds, then single bonds.

Re: Bond Length
In addition to the patterns of decreasing bond length from single to double to triple bonds, there is also a pattern in which larger atoms have a larger distance between each other, resulting in a longer bond length.

Re: Bond Length
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms
