The size of beads on the Marian Rosary are not always the same.  The Hail Mary beads are in groups of ten (also known as a "decade") and the Our Father beads are single beads that have a greater distance between them and the Hail Mary beads.  Both types of beads can be different sizes from each other or the same size.

The concluding rosary prayer is said at the conclusion of all prayers shown above.
