HERE'S THE NEW SIZE OF IPHONE 18 PRO'S DYNAMIC ISLAND, PER LEAKER

Summary from the TLDR Design newsletter

The iPhone 18 Pro is rumored to keep the pill-shaped Dynamic Island but shrink it by about 35%, reducing its width from roughly 20.8 mm to 13.5 mm, which should be noticeably smaller in everyday use. This redesigned Dynamic Island is expected to be exclusive to the iPhone 18 Pro and Pro Max.
