1136×640

1136×640 is a screen resolution. This means that the display has 1136 pixels horizontally and 640 pixels vertically. The total number of pixels is 727,040. This resolution was notably used by Apple for the iPhone 5 and iPod Touch (5th generation) devices, which featured a 4-inch display.

This resolution is an example of a widescreen aspect ratio. The aspect ratio is calculated by dividing the horizontal resolution by the vertical resolution, which in this case is 1136 / 640 = 1.775. This is very close to the common 16:9 aspect ratio (16 / 9 = 1.777...). For this reason, content formatted for 16:9 typically displays well on screens with a 1136×640 resolution with minimal distortion.

When 1136×640 was introduced, it was a step up in pixel count for mobile devices, allowing for more detailed images and text. It was a popular resolution for a period in the early to mid-2010s for smartphones before higher resolutions became standard.
