The Ultimate Guide To iPhone Resolutions

UPDATE: We have added the new iPhone Xs, iPhone Xs Max and iPhone Xr to the guide below.

The device screen may have lower pixel resolution than the image rendered in previous step. Before the image can be displayed, it must be downsampled (resized) to lower pixel resolution. Physical Pixels At the beginning, coordinates of all drawings are specified in Points are abstract units, they only make sense in this mathematical coordinate space. Points Point-based drawings are rendered into pixels. This process is known as rasterization. Point coordinates are multiplied by scale factor to get pixel coordinates. Higher scale factors result in higher level of detail. Rendered Pixels Finally, computed pixels are displayed on the physical screen. The PPI number tells you how many pixels fit into one inch and thus how large the pixels appear in the real world. Physical Device points. 320 × 480 3.5″ render at 1× (pixels) iPhone 2G, 3G, 3GS 3.5″ (points) 320 × 480 show at 163 PPI 320 × 480 640 × 960 3.5″ render at 2× (pixels) iPhone 4, 4s 3.5″ (points) show at 326 PPI 320 × 568 640×1136 iPhone 5, 5s, 5c, SE render at 2× 4″ 4″ (points) (pixels) show at 326 PPI 375 × 667 750 × 1334 4.7″ render at 2× (points) (pixels) show at 326 PPI 4.7″ 375 × 812 1125 × 2436 5.8″ iPhone X, render at 3× (points) (pixels) show at 458 PPI 5.8″ Xs 414 × 736 1242 × 2208 1080 × 1920 5.5″ show at 401 PPI (pixels) (points) (device pixels) 5.5″ render at 3× downsampling / 1.15 414 × 896 828 × 1792 6.1″ render at 2× (points) (pixels) show at 326 PPI 6.1″ 414 × 896 1242 × 2688 6.5″ iPhone Xs Max render at 3× (points) (pixels) show at 458 PPI 6.5″ NEW
