TV Watts: How Many Watts Does a 32 Inch TV Use?
Modern TVs are energy-efficient appliances requiring only a fraction of power when compared with some other common household appliances.
However, since most homes have several TVs and large/wide computer displays, people often ask how many watts does a TV use?
Published: March 11, 2023.
The best way to check/verify how many watts does YOUR TV use is to check the label on the back of the TV and write it down. Also, such information may be found in the TV's Owner's Guide or one can check it online by visiting the manufacturer's official site.
However, that is not always possible.
In order to quickly find out, at least approximately, how many watts does your TV use, it is necessary to know the screen size and its technology.
The following cross reference chart lists some of the most popular TV sizes (given in inches) and average required power (given in Watts), depending on the screen technology:
| Screen Size |
CRT | LED | OLED | LCD | Plasma |
| 15 | 65 | 15 | - | 18 | - |
| 17 | 75 | 18 | - | 20 | - |
| 19 | 80 | 20 | - | 22 | - |
| 20 | 90 | 24 | - | 26 | - |
| 21 | 100 | 26 | - | 30 | - |
| 22 | 110 | 30 | - | 40 | - |
| 24 | 120 | 35 | - | 50 | - |
| 30 | 140 | 38 | 52 | 60 | 150 |
| 32 | 150 | 41 | 57 | 70 | 160 |
| 37 | 170 | 44 | 66 | 80 | 180 |
| 40 | - | 50 | 72 | 100 | 200 |
| 42 | - | 57 | 75 | 120 | 220 |
| 45 | - | 65 | 82 | 130 | 250 |
| 50 | - | 72 | 89 | 150 | 300 |
| 55 | - | 80 | 98 | 180 | 370 |
| 60 | - | 88 | 107 | 200 | 500 |
Personally, if You still have a CRT (Cathode Ray Tube) TV and You still use it on a daily basis, don't - get a new LED flat screen (or some similar energy efficient TV) and keep the CRT TV as decor only.
Also, note that the plasma TVs, especially the older ones, generally need more power than the CRT TVs - replace your (older) plasma TV with a newer LED, OLED, QLED, ULED, LCD, or similar TV and save some money on your energy bills :)
32-Inch TV Wattage
32-inch TVs are very popular mid-size TVs used in kids' rooms, kitchens, and even as the main TVs in smaller homes and apartments.
Depending on the technology, 32-inch TV use (calculation is for 8 hours a day use, 1kWh=0.15 $US):
- CRT TV: ~150 watts, ~ 5.4 $US per month,
- LED TV: ~41 watts, ~1.5 $US per month,
- OLED TV: ~57 watts, ~2.1 $US per month,
- LCD TV: ~70 watts, ~2.5 $US per month,
- Plasma TV: ~160 watts, ~5.8 $US per month.
Note that these are average, maximum values that can be lower when the screen brightness and volume are decreased.
However, be aware that this energy is dissipated in the room in the form of heat, which can be even beneficial for heating during winter, but requires additional cooling energy by AC unit(s) during summer.
At first, these values are not significant, and maybe they are not, but if You have larger older TVs, energy savings may be much larger - for short, do your math and check is it worth to You to replace older TV with a new, more energy-efficient one.
