How do you measure television size refers to the process of determining the physical dimensions of a TV screen, usually diagonally from corner to corner. In simple terms, this tells you the screen’s size in inches or centimetres and helps you select the right television for your room, viewing distance, and furniture layout.
The main reason Australians search for this is to ensure TVs fit perfectly in their living rooms, bedrooms, or entertainment areas while delivering the best viewing experience.
Here’s why it matters: buying a TV that is too big or too small can compromise comfort, visual quality, and room aesthetics. Knowing how to measure television size helps you make informed purchasing decisions.
Measuring a TV is simple when you follow these steps:
Use a tape measure or ruler
Measure from the top-left corner of the screen to the bottom-right corner
Only measure the display area, not the bezel or frame
Measure horizontally across the screen for width
Measure vertically from top to bottom for height
Useful for planning placement in cabinets, on walls, or TV units
1 inch = 2.54 cm
Most TVs are sold by diagonal size in inches
Multiply screen height by 2–3 to get optimal viewing distance
Living rooms often need larger TVs than bedrooms
Measure available space to ensure TV fits
Leave extra space for airflow and cable management
Different TV types affect measurement considerations:
Slim profile
Standard diagonal measurement applies
Ultra-thin bezels
Diagonal size reflects almost the full screen
Quantum-dot panels
Measure diagonal for accurate room fit
Diagonal measurement still standard
Consider viewing angles and room layout
Diagonal remains main measurement
Ensure furniture accommodates extra depth for ports
Resolution doesn’t affect size measurement
Screen size impacts viewing distance for clarity
Knowing how to measure your television properly has several advantages:
Avoid TVs that are too big or too small.
Ensures clear picture without straining eyes.
Maintains balance with furniture and décor.
Accurate size helps select suitable brackets.
Improves comfort during long viewing sessions.
Prevents purchasing the wrong size and costly returns.
