One of the main differentiators between the models is the design and construction materials. While the iPhone 16 and iPhone 16 Plus feature an aluminum body and a tinted glass back, the Pro models (iPhone 16 Pro and iPhone 16 Pro Max) go for a more premium design, using titanium instead of aluminum. In addition, the finishes are also different: the standard models are available in vivid colors such as black, white, pink, teal and ultramarine blue, while the Pro models opt for metallic finishes in black titanium, white, natural and desert color.
