If you're asking for the ages it's 3years + If you are asking about the size of the pages they are 5x7inches. The page of stickers are 3x5inches. The paddle stampers don't have a specific size on them but on the part the child holds to stamp is about the height of 2 quarters and the stamper part where you would put the ink on is about the size of 1 quarter. The ink pad is about an inch :) Hope this answers your question!
