The film is exactly as large as the display. That was exactly my problem, because with my not too trembling fingers, I am still not able to apply the film accurately. As I tried, always, she stood to one side of a tiny piece over. This has always been an ugly edge with air inclusions, although just fine, but clearly visible. Repeated re-attaching, you collect sometime a dust particle and the perfect look is gone. My solution was to simply cut off so as to have some breathing room a small strip. Anyway, I now know why two films in the set are;). Otherwise, the film adheres well and does not let up even under varying temperatures and lively display fingering.
