Question: what is the size difference between iphone 5c and 5s?
Answer: Following on from the iPhone 5 before it, the iPhone 5S comes in a metal chassis measuring 123.8 x 58.6 x 7.6mm. This makes it smaller than the plastic iPhone 5C, which measures 124.4 x 59.2 x 8.97mm. The plastic hasn't made the 5C lighter though, as it comes in 20g heavier than the 5S; 132g to 122g.
