Buying a new television is exciting, but one of the most common questions shoppers ask is:
What size TV do I need?
With modern TVs available in sizes ranging from compact 32-inch models to massive 85-inch screens and beyond, choosing the right size can feel overwhelming.
The good news is that larger TVs are often more comfortable to watch than many people expect. Choosing the right size depends on your room, viewing distance and how you use your TV.
Why TV Size Matters
The size of your TV has a significant impact on your viewing experience.
A TV that is too small may struggle to create an immersive experience, while a TV that is too large for the room may feel overwhelming.
Finding the right balance helps ensure comfortable viewing for films, sport, gaming and everyday television.
How Are TVs Measured?
TVs are measured diagonally from one corner of the screen to the opposite corner.
For example:
- 55 Inch TV = 55 inches diagonally
- 65 Inch TV = 65 inches diagonally
- 75 Inch TV = 75 inches diagonally
- 85 Inch TV = 85 inches diagonally
The actual width and height of the TV will vary depending on the model and bezel size.
Best TV Sizes by Room Type
Small Bedrooms and Kitchens
For smaller rooms, a TV between 32 and 43 inches is often sufficient.
These sizes work well when viewers are sitting relatively close to the screen.
Living Rooms
For most living rooms, 55-inch and 65-inch TVs remain the most popular choices.
They provide an excellent balance between screen size and viewing comfort while fitting comfortably into most homes.

TV Size and Viewing Distance
A simple guide is:
| Viewing Distance | Recommended TV Size |
|-----------------|---------------------|
| 1.5 – 2 metres | 43" – 55" |
| 2 – 2.5 metres | 55" – 65" |
| 2.5 – 3 metres | 65" – 75" |
| 3+ metres | 75" – 85"+ |
These are general guidelines rather than strict rules.
Modern 4K TVs allow viewers to sit closer to larger screens without sacrificing picture quality.
Bigger TVs Are More Popular Than Ever
One of the biggest trends in recent years has been the move towards larger televisions.
Many customers who initially consider a 55-inch TV often discover that a 65-inch model fits their space comfortably.
Similarly, 75-inch TVs have become increasingly popular as prices have become more affordable.
A common comment from customers after upgrading is:
"I wish I had gone bigger."
What Size TV Is Best for Gaming?

When combined with modern gaming features such as HDMI 2.1, 120Hz refresh rates and low input lag, larger screens can significantly enhance gameplay.
