17–19″ 1280×1024 (5:4) viewport size

1280 × 1024CSS px · 1× DPR · 1280×1024 physical

By default the 17–19″ 1280×1024 (5:4) gives a full-screen web page a 1280 × 1024 CSS pixel viewport, drawn on a 1280 × 1024 pixel panel (device pixel ratio 1). That’s the size your media queries see.

Paste your address (or localhost:3000). doesitfit shows it at exactly 1280 × 1024, 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 1280 × 1024, but the browser’s own bars take some of it. In Chrome (Windows 11) a page gets about 1280 × 889 on first load (Chrome’s 87px tab strip + toolbar and the 48px Windows 11 taskbar, maximized window). That’s your real “above the fold”.

Tailwind breakpoints on real devices

Content width

With 16px of padding on each side your text column is 1248px; with 24px it’s 1232px. Text closer than 8px to the edge looks cramped (more).

Sharp images

A full-width image needs about 1280px of real pixels (1280 × 1).

<img src="hero-1280.jpg"
  srcset="hero-800.jpg 800w, hero-1280.jpg 1280w"
  sizes="100vw" alt="…">

Styles for this width

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

@media (max-width: 1280px) {
  /* screens 1280px wide and narrower */
}
