We purchased this Fathead collection for our 1 year old girl’s play room. The decals covered a 12x8 ft wall and approximately a 4x8 ft section of an adjacent wall. Of course, depending on how far apart you space them, it will cover different square footage. The clings are great quality and the colors are great! We are really pleased with the product. The only minor issue we had was that it is difficult to pee the first cling, and I slightly tore one of the clings. I still gave the product five stars because this is not a design flaw, and was totally my fault as I am not the most patient person. I definitely recommend this product.
