handover signalling messages size

 Hi experts

I have a question about  the handover signalling messages size and how you can calculate each one, I have tried the standard but I didn't find or get really how to calculate them, I hope you can help me with that

    It depended on ue information (UE capability, number of ERAB,,,) and eNB RRC Configuration (Data Forwarding, number of rrc measurement ie, SIBs,,,)

    So you can't calculate correct size.

    For reference, the following is handover signalling messages size in my handover wireshark log. (ERAB number = 1)
