Diagonale + Seitenverhältnis → Breite, Höhe, Fläche und wie viel größer B als A ist.
Nutzen Sie das bei der Größenwahl, wenn Sie prüfen wollen, ob ein größerer Fernseher ins Möbel passt oder wie viel größer ein Modell wirklich ist. Die Zahlen beschreiben nur das leuchtende Panel, nicht den Plastikrahmen. Danach können Sie die Hauptleinwand öffnen, um Smartphones oder Papier in dieselbe Szene zu legen.
Use the same unit for both TVs. Measure the lit glass corner to corner—the length shops print as the screen size.
Visible area (approx.): 48" × 27"
Visible area (approx.): 56.7" × 31.9"
Display B has 39.7% larger viewable area than Display A (panel only, excludes bezel).
Change in listed diagonal (B vs A): 18.2%. Positive means B is larger; negative means smaller.

Colours match the table columns above; overlapping outlines share the same bottom edge in this sketch.
| Metric | Display A | Display B |
|---|---|---|
| Diagonal (marketing) | 55" | 65" |
| Aspect ratio | 16:9 | 16:9 |
| Width (viewable) | 48" | 56.7" |
| Height (viewable) | 27" | 31.9" |
| Area (viewable) | 1.292,58 in² (~833.922 mm²) | 1.805,34 in² (~1.164.734 mm²) |
| Rough viewing distance | 8–14 in | 10–16 in |
Viewing distance is a rough living-room range (≈1.5–2.5× diagonal length), not a substitute for THX/SMPTE or your room layout.
How screen B compares to screen A
Percent uses screen A as the baseline (100%). Positive numbers mean B is larger; negative mean B is smaller. The last column shows the gap in everyday units.
| Metric | Change (%) | Approx. gap |
|---|---|---|
| Listed diagonal | 18.2% | +10" |
| Viewable width | 18.1% | +8.7" |
| Viewable height | 18.1% | +4.9" |
| Viewable area | 39.7% | +512,76 in² |

Compare phone sizes too
Smartphones are measured as physical bodies (glass + frame). The inch number here is the panel diagonal only—still useful when you want to place a phone next to a TV outline on the main canvas.
Tip: when you share the homepage link, TV outlines stay easy to pick out.
