9 Reasons You Should Buy an iphone 8 Instead of an iphone X

8. If you're upgrading from an iPhone 7 or iPhone 7 Plus, your old cases will fit.

The iPhone 8 and 8 Plus have near-identical dimensions to their predecessors, the iPhone 7 and 7 Plus, respectively. The new phones are slightly heavier, and there are slight differences in the new phones' height, length and depth, but all of the differences are less than a millimeter each, which means your old iPhone 7 cases will still fit.

The iPhone X has completely different dimensions from past iPhones, so your old cases won't work with this phone — one more expense to consider when buying this already-expensive phone.
