iPhone 15 Plus Dimensions and Screen Size
UPDATED NOVEMBER 1, 2026 · US ENGLISH · RESEARCH-BASED GUIDE
The iPhone 15 Plus is 160.9 mm high, 77.8 mm wide and 7.80 mm thick. It weighs 201 g and has a 6.7-inch OLED display. These numbers come from Apple's 2023 iPhone 15 Plus specifications, not the nearly identically sized 2024 iPhone 16 Plus. The 2 g weight difference is a useful reminder that matching screen diagonals do not imply identical model design or case fit.

What 6.7 inches really measures
The screen figure is measured diagonally. It does not equal the physical phone's width or height, and curved corners mean the actual viewable area is slightly smaller than a full rectangular measurement. For reading text, usable width and font-size settings matter as much as diagonal size. To check pocket fit, use the body dimensions rather than the display specification.
Comparing 15 Plus with 16 Plus
Both list a 6.7-inch diagonal and nearly matching height, width and thickness: 160.9 × 77.8 × 7.80 mm. Apple's weights differ: 201 g for 15 Plus and 199 g for 16 Plus. The newer model also changes controls and internal technology, so similar dimensions do not mean identical accessories. Always purchase cases identified for the precise phone generation.
Handling a large, older iPhone
A 77.8 mm width may feel substantial during one-handed typing. Cases, battery packs and grip accessories can help but make the overall device bulkier. If you regularly use a small bag or tight mount, measure the protected phone instead of assuming the bare measurements are enough. Device size also matters to wheelchair mounts, bike holders and in-car docks.
Why size is only one part of a used purchase
A 2023 iPhone 15 Plus might be available in a used or refurbished listing in 2026. Check screen condition, battery health, return rights and whether any repair altered water resistance. Original dimensions remain the same, but real-device condition can be very different. For users considering a newer Plus, the separate iPhone 16 Plus overview covers hardware beyond physical size.
