대각선 + 화면비 → 가로·세로·면적, 그리고 화면 B가 화면 A보다 얼마나 더 큰지.
크기를 고를 때, 큰 TV가 가구에 맞는지 확인하고 싶을 때, 「65인치가 55인치보다 얼마나 큰지」 알고 싶을 때 사용하세요. 숫자는 발광 패널만 나타내며 플라스틱 베젤은 포함하지 않습니다. 요약을 읽은 뒤 메인 캔버스에서 스마트폰이나 종이와 같은 장면에 놓을 수도 있습니다.
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.
