What age is the right starting point for jigsaw puzzles?

For ages 2-4, verified-purchase reviewers favor chunky wooden peg puzzles and large floor puzzles with a small number of big pieces. Around ages 5-7, kids typically graduate to 48-100 piece cardboard puzzles, and 100-150 piece sets suit confident 7-and-up puzzlers. Most boxes in this category print a recommended age range that buyers say tracks reasonably well.
