how many watts does a tv use
Most modern TVs use roughly 50–200 watts while on , with smaller, efficient LED sets near the low end and large or older technologies toward the high end.
Quick Scoop: How Many Watts Does a TV Use?
- Many modern LED/LCD TVs : about 50–200 W when running.
- A typical 32" LED TV : around 30–55 W.
- A typical 55–65" LED TV : often 60–120 W.
- Older or less efficient types (plasma, CRT): can run 100–500 W or more, especially at larger sizes.
In everyday terms: a modern flat‑screen TV usually uses about as much power as a bright light bulb , not as much as a space heater.
Typical Wattage by TV Type
| TV type | Approx. running watts | Notes |
|---|---|---|
| LED | 30–100 W per hour | [7][5][9][1]Most energy‑efficient common type. |
| LCD | 50–150 W per hour | [3][5][9][1]Generally a bit higher than LED of same size. |
| OLED | ~60–200+ W per hour | [5][9][1][3]Great picture; uses more power as size/brightness rise. |
| Plasma | 100–300+ W per hour, up to ~500 W | [9][1][5]Much less efficient; mainly older TVs. |
| CRT | ~100–400 W | [1][5][9]Old tube TVs; power‑hungry for their size. |
Size vs. Power (Real‑World Examples)
- A 32" LED : ~30–55 W.
- A 43" TV : ~48 W on average.
- A 55" TV : around 60–100 W typical for LED, ~98 W for OLED, and ~180+ W for older LCD or ~370 W for plasma.
- A 65–75" LED : roughly 90–115 W in many tests.
You can estimate electricity per day:
If your TV is 100 W and you watch 4 hours, it uses 100×4=400100\times
4=400100×4=400 watt‑hours, or 0.4 kWh.
What Actually Affects TV Wattage?
Key factors that change how many watts a TV uses :
- Screen size – Bigger screens = more pixels to light = more watts.
- Display technology – LED is usually most efficient; OLED, plasma, and CRT use more per inch.
- Brightness / picture mode – “Vivid” or max brightness can noticeably raise wattage.
- Resolution & features – 4K/8K, high refresh rates, and powerful speakers all add a bit.
- Standby mode – Even “off,” most TVs draw 0.5–3 W in standby.
How to Check Your Own TV’s Watts
You can get a more exact answer for your specific TV:
- Look at the rear label or manual – It usually lists power (W) or volts and amps. Multiply V×AV\times AV×A to get watts, e.g. 120 V×1 A=120 W120\text{ V}\times 1\text{ A}=120\text{ W}120 V×1 A=120 W.
- Use a plug‑in power meter – Shows real‑time watts for whatever content and settings you’re using.
- Check eco/energy menus – Some smart TVs show estimated consumption in the settings or energy‑saving screen.
Quick Cost Example
Suppose you have a 90 W LED TV and watch 3 hours per day :
- Daily energy: 90 W×3 h=270 Wh=0.27 kWh90\text{ W}\times 3\text{ h}=270\text{ Wh}=0.27\text{ kWh}90 W×3 h=270 Wh=0.27 kWh.
- If electricity costs 20 cents per kWh, that’s about 5–6 cents per day.
So for most households, a TV’s power use is modest , especially with newer LED models, but it can still add up if it’s on many hours a day or if you have a large, bright, older screen.
Bottom line: For “how many watts does a TV use,” the practical answer is usually 50–200 W , depending mainly on type, size, and settings , with modern LED TVs at the lower end and older plasma/CRT sets at the higher end.
