IPhone 5 screen protector that fits perfectly?

You know when you buy a screen protector and it's always 3-4 mm smaller than the screen, well I would like to buy a screen protector that's matt and fits perfectly on the screen, until the edges

I find the glass screen protectors cover all the screen. The protector is a piece of real tempered glass and the idea is so that if you drop your phone, the protector will crack instead of your actual screen. And since it's glass it doesn't even feel like you have a protector on! It's great! Mine is by the brand bodyguard or something like that and is about $30 - $35. While pricy now, it's much cheaper than having to get a new screen if you crack yours
