How to take a screenshot at an exact size like 1920×1080
Resizing the browser window until it happens to be 1920×1080 is a losing game — the toolbar, the scrollbar and your device pixel ratio all get in the way. ScrnCap's fixed-size mode captures the page at the exact dimensions you ask for, from a preset or a size you define yourself.
Doing it manually in Chrome
- 1Open DevTools with F12 and turn on the device toolbar (Ctrl+Shift+M).
- 2Enter a custom device size, for example 1920×1080.
- 3Set the zoom to 100% and reload so the layout settles.
- 4Use the DevTools command menu to capture a screenshot of the viewport.
Where the manual way falls short
- DevTools has to stay open and the page renders inside an emulated viewport, so what you capture is not always what a real visitor sees.
- You have to redo the whole setup for every new size, and there is nowhere to store the sizes you use repeatedly.
Doing it with ScrnCap
- 1Open ScrnCap and choose Fixed size.
- 2Pick a preset such as 1920×1080, or add your own size — it stays in the list.
- 3Capture. The image comes out at exactly those dimensions, ready to export.
Free, offline and no account needed — the capture, the annotation and the export all happen on your own machine.
