What this device means for responsive design
The Amazfit GTR 4 uses a viewport of 227 x 227 PX, which makes it a key target for desktop layout testing. Designers and developers should rely on the viewport value for CSS breakpoints, while the native resolution and DPR help explain image sharpness and rendering density.
Example breakpoint
@media (max-width: 227px) {
/* target layouts around Amazfit GTR 4 width */

CSS Media Query
@media (min-width: 227px) and (max-width: 227px)Responsive design notes
Use the viewport for layout decisions, the native resolution for asset planning, and the DPR when understanding how CSS pixels map to physical pixels.
Use viewport for CSS
Focus on 227 x 227 PX when planning breakpoints and layout widths.
Use resolution for assets
The native 454 x 454 PX resolution helps guide image export sizes and display sharpness.
Use DPR for scaling
A DPR of 2 XHDPI means this screen maps multiple physical pixels to one CSS pixel.

What is the screen resolution of the Amazfit GTR 4?
The Amazfit GTR 4 has a 454 x 454 PX screen resolution on a 1.43 INCH display, resulting in a pixel density of 454 PPI.
What is the CSS viewport size of the Amazfit GTR 4?
The Amazfit GTR 4 has a CSS viewport of 227 x 227 PX. This is the value returned by window.innerWidth and window.innerHeight in JavaScript, and the value that CSS media queries respond to.
What CSS media query should I use for the Amazfit GTR 4?
To target the Amazfit GTR 4 viewport, use: @media (max-width: 227px). For a mobile-first approach, this targets the device at and above its viewport width.
What is the pixel density (PPI) of the Amazfit GTR 4?
The Amazfit GTR 4 has a pixel density of 454 PPI, which corresponds to a device pixel ratio (DPR) of 2. This means CSS pixels are scaled up to produce crisp, high-resolution rendering on the physical display.
