Responsive testing notes

How to use this viewport reference

Use 820 × 1180 as a practical starting point for testing iPad Air 11-inch layouts, then confirm the live viewport in the browser you are targeting.

Test CSS width

Start breakpoint checks around 820px, then resize slightly above and below that value.

Record DPR

A DPR of 2 affects image sharpness, canvas rendering, and screenshot interpretation.

Verify live values

Use the live checker because browser chrome, orientation, zoom, and OS scaling can change the usable area.

Source and update note

Reference values, not guarantees

This page is built from the ScreenMetricLab device viewport dataset. Values are normalized for practical QA and design use, but they should be verified on real devices or browser emulators before publishing critical layouts.

Record source: Physical display data should be verified against Apple specs; split view can change CSS viewport.

Updated 2026-06-26

Device references should be reviewed regularly as browsers, OS scaling, and hardware options change.

Use with live tools

Pair this page with the viewport checker, DPR checker, and screen resolution checker for better QA notes.

Frequently asked questions

What is the CSS viewport size for iPad Air 11-inch?

The reference CSS viewport for iPad Air 11-inch is 820 × 1180. Live browser values can still change because of zoom, browser UI, OS display scaling, orientation, and responsive mode.

No. The physical resolution for this device is 1640 × 2360, while the CSS viewport is the layout area that websites normally use for responsive breakpoints.

Which value should I use for responsive testing?

Use the CSS viewport width first when checking breakpoints and layout bugs. Include DPR and physical resolution as extra context in QA reports.

Why can my live result be different from this reference?

Browser chrome, zoom, operating-system scaling, accessibility settings, split view, and orientation can all change the viewport reported by JavaScript.
