About 6 Pieces (9.85in x 11.8in)
Please note:
we are 6 small pieces - 3 large pieces (2 of the small pieces are joined together)

This set come with 6 squares, but two of them are connected, making it 3 separate pieces. The pads will cover about half of a crib meaning if you want to surround the entire (full-sized) crib you will need two sets.
