Root assembly of a wind turbine blade for a wind turbine, wind turbine blade and wind turbine

A root assembly of a wind turbine blade for a wind turbine, comprising:

• a root portion comprising at least two root segments being joined together at root segment interfaces formed between the at least two root segments;
• a root attachment face of the root portion attached to a bearing or a hub flange of the root assembly by multiple bolts, wherein each of the multiple bolts is connected to one of a multiple of bolted connection means fixedly arranged within the root segments such that the multiple bolts are arranged adjacent to each other along a circumference of the root portion and the bolted connection means are arranged adjacent to each other along the circumference of the root portion;
• and
• adjacent bolted connection means are offset from one another in a way such that the adjacent bolted connection means are provided at different distances from the root attachment face,
• wherein in at least one of an interface pair of bolted connection means, the bolted connection means of the at least one interface pair are provided within different root segments of the at least two root segments and are arranged closest to the root segment interface between the different root segments, the two bolted connection means of the at least one interface pair are provided at the same distance from the root attachment face.
