Question 1

How much bigger is a 65 inch TV than a 55 inch?

Accepted Answer

On the same 16:9 shape, a 65″ picture is about 18% wider and taller than a 55″, and about 40% more picture area—not “10 inches bigger” in every direction. Use the presets above to compare your two sizes.

Question 2

What does “inch” mean on a TV or monitor spec?

Accepted Answer

It is the diagonal across the lit glass from corner to corner—not the plastic bezel. Width and height come from that diagonal plus the aspect ratio. Two displays with the same inch label but different shapes (for example 16:9 vs 16:10) will still differ in width, height, and total picture area. The outer cabinet can also look different because bezels, speaker bars, and stands vary by model.

Question 3

How do I measure the screen so it matches the store listing?

Accepted Answer

Hook a tape measure on one corner of the glass and stretch straight to the opposite corner. Use the same unit (inches or centimetres) for both screens on this page. Measuring the outer frame or wrapping the chassis will read larger than the published screen size.

Question 4

How far should I sit—is this a professional viewing-distance calculator?

Accepted Answer

Comfortable seating depends on resolution, eyesight, taste, and your room. We show a broad band from the diagonal (about 1.5–2.5×) so you can sanity-check sofa placement—not to replace THX/SMPTE rules, HDR tuning, or gaming-specific seating math. For a precise sweet spot, use specialist guides.

Question 5

Why use this instead of a printed TV size chart?

Accepted Answer

Paper charts list a handful of standard sizes and rough width/height rows. Here you enter any two diagonals and aspect ratios—handy when you are choosing between specific models or checking whether two sets fit side by side on a cabinet.

Question 6

Bedroom vs living room—what besides the inch number matters?

Accepted Answer

Start from real space: measure the wall, shelf depth, or cabinet opening, then compare those limits to the picture width and height we calculate. The marketing inch alone does not tell you if it fits. Pair that with how deep your room is for viewing distance.

Question 7

Why exclude bezels—and can I use brand listings for custom furniture?

Accepted Answer

Frames, speaker strips, and stands change every year and by region. We compare the glowing rectangle so two panels stay fairly comparable. Store pages often highlight whole-product styling; for recessed walls, niches, or built-ins, always confirm outer cabinet dimensions in the manual.

Question 8

Why does my 28″ 16:9 look different from 28″ 16:10?

Accepted Answer

Same diagonal length still allows different widths and heights when the shape changes. That is why total picture area can move by several percent.

Question 9

Can I use this for monitors, LCD TVs, or HDTVs?

Accepted Answer

Yes. Any rectangular screen uses the same geometry: listed diagonal plus aspect ratio gives viewable width and height. This tool compares physical panel size—the lit glass—not pixel resolution or HDR quality.

Question 10

Do 4K or 8K screens change how far I should sit?

Accepted Answer

Higher resolution lets many people sit closer before individual pixels become distracting—but room size, brightness, HDR, and motion comfort still vary. This page estimates panel geometry, not a pixel-perfect seating formula.

Question 11

Should I enter the diagonal in inches or centimetres?

Accepted Answer

Either works—pick one unit for both displays so the comparison stays fair. Tables and the “approx. gap” column follow the unit you choose above.
