The size was perfect for my bathroom window but the application was not easy. neither was cutting the film to fit the two panel of the window. It's up for now but not sticky and will likely fall off in the next week. I'm watching it. Update 2018: This film is still on the window and held up surprisingly well. It still looks good and is doing its job. Update 2020: The film is still clung to the window and i am changing my rating to a 4. If you can get passed the set up process this product is good and will last for years.
