For the last three generations, the iPhone has been available in two sizes, the regular 4.7-inch model and the larger 5.5-inch model. If you wanted a bigger screen, your only option was to go for the Plus.

However, this year Apple has introduced three new models with the addition of the iPhone X. Although the new iPhone X is physically smaller in dimensions than the iPhone Plus, it has a larger screen. And other than the lack of Touch ID, the iPhone X is arguably a superior product than the iPhone 8 Plus.
