Unfortunately the design instructions say it is 5 feet 3 inches high. I had measured for this and after placing all but the top tiles, realized it is closer to 5 feet 7 inches high, and the top row wouldn’t fit, so I had to remove all tiles and start all over. Now I have a bunch or partially broken tiles and some residual glue from adhesive stickers on my walls. But the design is lovely and really does block noise. However the company really should have the correct dimensions listed on website and instructions.
