POCO X7 Pro screen size & viewport

The POCO X7 Pro renders web pages at a CSS viewport of 412 × 915 in portrait (915 × 412 in landscape).

What these numbers mean

412 × 915 is the CSS viewport size — the coordinate space your layout, media queries and vw/vh units work in. It is not the hardware pixel count: the POCO X7 Pro packs more physical pixels behind each CSS pixel (its device pixel ratio), which is why images meant for it should be exported at 2× or 3×.

For a phone this size, a layout should already be at its single-column mobile breakpoint.

Targeting it in CSS

/* Styles for viewports up to the POCO X7 Pro */
@media (max-width: 820px) {
  .container { padding-inline: 16px; }
}

/* Exactly the POCO X7 Pro in portrait */
@media (width: 412px) and (height: 915px) { /* … */ }

Common things that break at 412px wide

• Fixed-width elements wider than 380px (content minus typical padding) cause horizontal scroll.
• Tap targets under 44×44 CSS px are hard to hit.
• Sticky headers taller than ~15% of 915px eat too much of the screen.
• Text set below 16px triggers zoom-on-focus in form fields on iOS.
