What a web page actually sees
The full viewport is 1366 × 768, but the browser’s own bars take some of it. In Chrome (Windows 11) a page gets about 1366 × 633 on first load (Chrome’s 87px tab strip + toolbar and the 48px Windows 11 taskbar, maximized window). That’s your real “above the fold”.

|---|---|---|
| Full viewport | 1366px | 768px |
| Visible on first load (Chrome (Windows 11)) | 1366px | 633px |

About these numbers
Confidence: High: confirmed by more than one independent source. Windows picks a “recommended” scale per panel and manufacturers often override it; Chrome rounds fractional sizes up (2560×1600 at 150% → 1707×1067).
