What the safe areas mean
| Area | Size | Keep inside |
|---|---|---|
| Action safe | 93% (3.5% margin per side) | Important action, faces, ball in play |
| Title / graphics safe | 90% (5% margin) | Text, logos, lower thirds, tickers |
| Legacy SD title safe | 80% | Only if you still deliver to old 4:3 CRT chains |
| 4:3 centre cut | 1440 × 1080 of 1920 × 1080 | Graphics that must survive SD simulcast |
Modern flat panels overscan very little, but phones, social players and some set-top boxes still crop or overlay UI. Treat title safe as your hard boundary. For lower thirds, try the lower-third generator, whose output already respects these margins.
