Will my iPhone 6 case fit the iPhone 6s?

The iPhone 6s has the same form factor as its predecessor the iPhone 6, except that it is 0.01 inches thicker and wider. This increase is so minor that it should not affect cases, but just to be sure you may want to check with the manufacturer. For example, Speck announced on its Facebook page that all its iPhone 6 and iPhone 6 Plus cases fit the next generation s-devices.
