Browser bars and the visible area

The viewport height is the whole screen, but Chrome on Android keeps part of it for its own interface. In portrait about 80 px at the top (status bar and address bar) and 48 px at the bottom (navigation bar) are covered, leaving roughly 360 × 612 CSS px for the page when it first opens. In landscape the bars take about 80 px.

That is why 100vh can be taller than what people see. Use 100svh for the smallest visible height, 100dvh for the current one, and keep the most important content and buttons within the first 612 px.

Rather than targeting one device, write fluid styles and add breakpoints where your layout needs them — the same CSS then works on the 6 other devices with the same width and hundreds of models with similar sizes.

Testing on the Samsung Galaxy S8 & S9

Android phones render with Chromium, the engine behind Chrome. Pixel ratios like 4 mean thin borders and small images can look blurry or uneven — check them at the real ratio. See how to test a website on Android.
