No they are not regulation size however the are GREAT ….GREAT FOR adults and kids alike. You can use them indoors or outdoors. They are super easy to put together. When I assembled them I thought oh boy these are not gonna be sturdy at all ….but i was wrong they are indeed sturdy. The bags are about 1/4 size regulation size bags but still work for this. Great for kids room, game room, beach , yard and so so much more.
