These figures come from a UK retailer’s smart TV buying advice, and the price band is an undated listing, so confirm current prices before relying on it.

How to choose a TV starts with the room: measure how far the seat is from the screen, match the size to that distance, then pick a panel type for the room’s lighting and a price you can hold.

The consumer technology hub applies the same room-and-budget thinking across devices, including how to choose a tablet.

Seating distance and room size

Seating distance is the best starting point for screen size, and the type of room narrows the choice further. The retailer guidance pairs 40–50 in screens with seats 5–7 ft away and 70–85 in screens with seats 10+ ft away. These bands are guidance rather than a hard rule. They still protect you from the commonest mistake, which is buying a size chosen for a different room from the one you have.

Match the size to the seat and the room

  • Bedrooms and kitchens: the retailer points to screens under 50 in. A set here is usually watched from close by, so a very large panel gains little.
  • Living rooms and home theatres: the same guidance suggests 55–75 in. This is a wide range, so do not pick from it by room label alone.
  • Seating distance breaks the tie: if your living room sits near the edge of two bands, go by the measured distance from the sofa to the wall. Room labels are only a rough proxy for how far you actually sit.

Fit, mounting and full dimensions

Samsung advises making the most of your space by purchasing the largest screen that will fit. That advice works best when the budget and the seating distance both agree with it. Two practical points decide whether a given size actually fits.

  • Wall mounting gives more headroom: Samsung notes that a wall-mounted TV usually leaves plenty of room, so a mounted set can go larger than one that has to sit on furniture.
  • Check the whole set, not just the diagonal: Samsung says the full dimensions of its TVs are listed under Specs as ‘Set Size’. Compare that figure with your entertainment center before you order, because the screen size alone does not tell you whether the frame and stand fit the space.

Budget and the price of size

Budget decides how far up the size range you can go, because prices climb steeply once screens get large. AARP notes that prices pop up much higher for screens more than 50 in on the diagonal. That makes 50 in a natural decision point: below it, choices are easy to price, and above it, each step up needs a stronger reason.

  • Decide whether money goes into inches or into the panel: a bigger screen and a better panel type compete for the same budget. If the room is bright, a suitable panel type for that room is worth protecting before adding more inches.
  • Use the UK price band as a reference point: the retailer says that between £400–£800 you can expect higher-quality smart TVs with added features and smart capabilities. The listing is undated, so check it against current prices.
  • Fix the ceiling before you browse: with a firm number, the size and panel choices below become a filtering exercise rather than a temptation to drift upward.

OLED, QLED and Mini-LED for your lighting

Room lighting is the main deciding factor between OLED, QLED and Mini-LED. Dark rooms favour OLED, and bright rooms favour QLED or Mini LED. The trade-offs below explain why.

OLED or QLED?

  • Choose OLED for dark rooms and films: the retailer recommends OLED if you prefer a cinematic and immersive experience with perfect blacks and better contrast.
  • Choose QLED for bright rooms: the same guidance asks whether your living room is incredibly bright and, if so, suggests a Mini LED or QLED set. IGN adds that the brighter the display, the less likely it is to be affected by glare from external sources.
  • Treat Mini-LED as a bright-room alternative: the retailer lists it alongside QLED for bright rooms, but notes it does not reach OLED’s true black levels. Pick it when daytime brightness matters and you can accept less deep blacks.

Why the panels behave differently

The difference comes from how each panel makes light. OLED has self-lit pixels, which the retailer credits with infinite contrast, so each pixel can go fully dark. The costs are a potential burn-in risk and lower peak brightness compared with QLED. QLED still relies on a backlight, so its blacks are not as deep as OLED’s.

Putting those facts together gives a clear warning. An OLED in a sun-filled room works against its lower peak brightness, and a bright-room set watched mostly after dark gives up the deep blacks you would probably value most. Choose for the lighting you will have most of the time, not the best-case demo in a showroom.

Inputs, HDMI 2.1 and refresh rate

The inputs you need depend on what you plug in, and anyone gaming on a current console or PC should check for HDMI 2.1 first. Work out the list of connected devices before you compare ports.

Smart TV platforms and daily use

The smart TV platform comes with the brand, so choosing a set also chooses the interface you will use every day. The retailer lists Samsung’s Tizen, LG’s webOS and Sony’s Google TV as the main examples, describing Tizen as fast, app-rich and strong on smart integrations.

Because the platform is tied to the brand, a panel you like on a platform you dislike is a real compromise. Before deciding, confirm that the streaming apps your household uses are available on that platform.

Frequently asked questions

How is TV screen size measured?

Samsung says TV screen size is measured from corner to corner, diagonally, in inches.

Is 8K worth buying?

Samsung describes 4K resolution as the new standard of quality, with 8K now available as the sharpest option. A 4K set is the standard choice unless 8K is a priority for you.

What if the TV has too few HDMI ports?

IGN notes you can buy HDMI port dongles, though they can be hit-and-miss with quality. Counting your devices against the ports before you buy is the more reliable route.

Should I connect the TV by ethernet or Wi-Fi?

IGN says using an ethernet cable will guarantee a more consistent connection, so use ethernet where the TV is near the router and streaming reliability matters.
