20″ 1600×900 (legacy) viewport size

1600 × 900CSS px · 1× DPR · 1600×900 physical

By default the 20″ 1600×900 (legacy) gives a full-screen web page a 1600 × 900 CSS pixel viewport, drawn on a 1600 × 900 pixel panel (device pixel ratio 1). That’s the size your media queries see.

See your site on a 20″ 1600×900 (legacy)

Paste your address (or localhost:3000). doesitfit shows it at exactly 1600 × 900, with Chrome (Windows 11)’s bars if you want them, and tells you if anything spills.

What a web page actually sees

The full viewport is 1600 × 900, but the browser’s own bars take some of it. In Chrome (Windows 11) a page gets about 1600 × 765 on first load (Chrome’s 87px tab strip + toolbar and the 48px Windows 11 taskbar, maximized window). That’s your real “above the fold”.

Content width

With 16px of padding on each side your text column is 1568px; with 24px it’s 1552px. Text closer than 8px to the edge looks cramped (more).

Sharp images

A full-width image needs about 1600px of real pixels (1600 × 1).

<img src="hero-1600.jpg"
  srcset="hero-800.jpg 800w, hero-1600.jpg 1600w"
  sizes="100vw" alt="…">

Styles for this width

Content-first breakpoints beat device lists, but if something breaks at this width:

@media (max-width: 1600px) {
  /* screens 1600px wide and narrower */
}
