 More sophisticated, but still common, jigsaw puzzles come in sizes of 1,000, 1,500, 2,000, 3,000, 4,000, 5,000, 6,000, 7,500, 8,000, 9,000, 13,200, 18,000, 24,000, 32,000 and 40,000 pieces.Jigsaw puzzles that are geared towards children may have many fewer pieces, typically much larger.For very young children, a puzzle with as few as 4 to 9 "large"-size pieces (so not a choking hazard) are common.
