❓ FAQ
What is screen resolution?
Screen resolution refers to the number of pixels displayed on a screen, typically expressed as "width × height" (e.g., 1920×1080). Higher resolution means more content can be displayed with sharper images.
What is DPR?
DPR (Device Pixel Ratio) is the ratio of physical pixels to CSS pixels. A DPR of 2 means each CSS pixel maps to 4 physical pixels (2×2), resulting in sharper displays.
What can the comparator do?
It allows you to compare screen size, resolution, DPR, and other parameters of different devices side by side, helping frontend developers with responsive design decisions.
