The convention at weddings is for the Bridegroom to stand, be seated or be photographed on his Bride’s right; after all, he is her right-hand man!
For anything larger than a small, informal reception, a wedding seating plan is likely to make a significant difference to the success of your reception. In the UK, the Bride and Bridegroom would traditionally sit in the middle of the wedding top table, flanked by the Bride’s parents, then the Bridegroom’s parents, and, finally by the Best Man and Chief Bridesmaid. So, from the guests’ view, sitting left to right: Matron of Honour, Bridegroom’s Father, Bride’s Mother, Bridegroom, Bride, Bride’s Father, Bridegroom’s Mother and Best Man.
