I need to emulate an iPhone X on Chrome. I have found the info below:
Height: 5.65 inches (143.6 mm)
Width: 2.79 inches (70.9 mm)
Can you tell me which values should I give to the form below?
This is what Device pixel ratio (DPR) is
If you want to emulate a Retina device from a non-Retina machine or vice versa, adjust the Device pixel ratio. The device pixel ratio (DPR) is the ratio between logical pixels and physical pixels. Devices with Retina displays, such as the Nexus 6P, have higher pixel density than standard devices, which can affect the sharpness and size of visual content.
According to the iPhone X Human Interface Guidelines, you should enter:
Because the scale factor is 3, you should divide the physical resolution (1125px × 2436px) by 3 to get the logical resolution.
