Use Chrome DevTools’ Responsive mode to set a mobile portrait viewport, then capture either the visible screen or the full page. OPPO lists the Reno11 5G’s physical display as 2412 × 1080 pixels, but that is not its browser’s CSS viewport size. Don’t enter the panel resolution as CSS dimensions: use a verified Reno11 profile or measure the live phone, and treat DevTools as an approximation.
What “OPPO Reno11 size” means for a website screenshot
OPPO’s Singapore specification page identifies the Reno11 5G as model CPH2599 and lists a 6.7-inch FHD+ display with a physical resolution of 2412 × 1080 pixels (OPPO Reno11 5G specifications). Those are panel pixels, not the width and height a website uses for responsive CSS layout.

Web pages lay out against a CSS viewport. Device pixel ratio (DPR) describes the ratio of physical screen pixels to logical CSS pixels; Chrome DevTools lets you configure viewport dimensions and, separately, DPR (Chrome DevTools device mode documentation). The official OPPO page does not specify the Reno11’s browser CSS viewport or DPR, so a calculation based on an assumed DPR would not establish the phone’s actual browser dimensions.
Capture the page in Chrome DevTools
- Open the page and DevTools. In desktop Chrome, load the page you want to inspect and open DevTools. Toggle the Device Toolbar using its toolbar button or the DevTools device emulation command.
- Choose a portrait viewport. Select Responsive in the device dropdown and enter the verified Reno11 CSS viewport width and height. If your installed DevTools offers a verified profile for the handset, you can select it; otherwise measure the live phone as described below. Do not enter 2412 × 1080 as CSS dimensions.
- Set device behavior and pixel density as needed. Choose the mobile device type when touch and mobile rendering behavior matter. Configure DPR when the exported image’s pixel density or high-density assets matter. For CSS breakpoint checks, the viewport dimensions are the key input.
- Inspect the layout. Check the fold, text wrapping, navigation, images, and controls at the selected dimensions. Rotate to landscape only when that is the orientation you need to assess, and record the changed dimensions.
- Choose the capture extent. In the Device Toolbar, open More options. Choose Capture screenshot for the visible viewport, or Capture a full size screenshot to include content beyond the visible screen. Chrome documents these as separate capture commands.
- Keep the setup reproducible. Note the Chrome version, orientation, viewport width and height, DPR, mobile/desktop device type, and whether the image is viewport-only or full-page.
Find the actual Reno11 browser viewport
For a closer match, measure the live phone rather than inferring browser dimensions from the panel specification. Open the page in the phone’s browser and use a small diagnostic snippet in the page’s developer console if that browser provides one, or temporarily inspect these values in a page you control:

window.innerWidth
window.innerHeight
window.devicePixelRatioinnerWidth and innerHeight report the current layout viewport in CSS pixels; devicePixelRatio reports the browser’s device pixel ratio. Record whether browser chrome, orientation, or display settings differ between measurements. If the actual phone is not available, use only a device profile whose Reno11 dimensions have been independently verified, and label the result as an emulation rather than an exact-device capture.
Choose the right screenshot type
- Viewport screenshot: use it to review the visible fold, what a visitor sees immediately, or a responsive breakpoint at a particular screen position.
- Full-page screenshot: use it to inspect content extending below the fold. Page height and lazy-loaded content can affect what appears in a full-page capture, so check that the page has finished loading before saving it.
- Device emulation: use it for repeatable responsive-layout checks in desktop Chrome.
- Physical handset: use it when the result depends on the actual phone, its browser, or device-specific behavior. Chrome describes Device Mode as a “first-order approximation” rather than a real mobile device (Chrome Device Mode guidance).
Or skip the browser setup
ScreenshotNeo can return a website screenshot with one GET request. Its options include viewport dimensions and device settings, so provide the verified CSS dimensions you want to emulate; the Reno11’s panel resolution alone is not a verified CSS viewport. See the ScreenshotNeo API documentation.

Troubleshooting
- The result looks too wide or too narrow: verify that you entered CSS viewport dimensions, not 2412 × 1080 panel pixels. Check the width and height of the live phone or use a verified profile.
- Responsive breakpoints do not match the handset: confirm the viewport width, orientation, and device type. DPR affects pixel density, but it is not a substitute for the correct CSS viewport width.
- Screenshot stops at the fold: use More options > Capture a full size screenshot rather than the viewport-only command.
- Lower-page images are missing: wait for the page to load and scroll through the content before capturing; lazy-loaded images may not appear until they are requested.
- It differs from the actual OPPO browser: desktop Device Mode is an emulation, not a run on the Reno11. Validate on the phone when browser or hardware behavior matters.
What to record with the screenshot
For a useful comparison later, save the viewport width and height in CSS pixels, DPR, portrait or landscape orientation, browser and version, capture date, and screenshot type. That context distinguishes layout differences from pixel-density or full-page capture differences.
