If you’re wondering how to measure a TV, what size suits your space, or whether a larger screen is worth it, this guide has you covered. We’ll walk you through measuring your TV, ideal viewing distances, room considerations, and mounting options, so you can find the perfect setup for the best viewing experience.
How is TV Screen Size Measured?
TV screen size is measured diagonally from one corner of the screen to the opposite corner . This measurement is given in inches and refers to the display area only, not the overall dimensions of the TV.
Step-by-Step: How to Measure a TV Screen
- Grab a tape measure
- Place the tape at the bottom left corner of the screen (just the screen, not the frame)
- Stretch it to the top right corner
- Read the measurement in inches – this is your TV's official screen size
For example, if the diagonal measurement is 75 inches, you have a 75-inch TV.
Important: this is the size of the screen only. It does not include the stand, bezel or any other part of the TV. If you're buying a new TV online, check the unit dimensions in the specifications tab on the product page for a proper fit.
How Big Should I Go?
The rule of thumb for TV size is get the biggest TV your budget will allow. A larger screen creates a more captivating viewing experience, making everything you watch more lifelike.
Before you go all in on the biggest screen you can find, consider the room size and viewing distance to help find the perfect size. Make use of available resources to compare different TV sizes and find the one that best fits your space and budget.
Room size: will your TV fit in the room?
Where are you planning on watching? The lounge or the bedroom? The bathroom or the kitchen? The toilet?! Consider the size of the room and if the TV will physically fit and don’t get caught out with a 75” toilet TV.
When measuring for a new TV, remember to check the actual width, height and depth of the TV model. Check the weight of the TV model and make a plan if you need assistance to lift it.
What to measure before buying a TV:
Wall mounting space: check the wall's available width and height. A larger TV may not fit between windows or adjacent to a doorway.
TV stand or cabinet size: if you're using a TV cabinet, make sure it's wider than the TV base. Measure both the width and the depth of the cabinet.
Viewing angle: Mark where the middle of your TV will be on the wall and sit where you usually would sit to watch TV. Is the viewing angle comfortable? An awkward viewing angle can cause neck pain, or at least be very annoying over time.
Power points: make sure there's a power point near the TV to plug it in. If there isn't one, make sure to plan your cable management.
Television viewing distance: how far should you sit for the best immersive experience?
The term “viewing distance” is just a technical way of saying “how far you sit from the TV screen”. If you sit too close it might be hard on your eyes, if you sit too far away the experience is less enjoyable. Generally, the further away you sit from the TV, the bigger the TV will need to be in order to be satisfying to watch.
There are numerous resources available to help you calculate the optimal viewing distance for your TV size.
The general formula for calculating a TV's recommended viewing distance
TV Size (in inches) x 1.2 = Recommended Viewing Distance.
Example: 75 inches x 1.2 = 90 inches (2.3 metres). In this example the minimum recommended viewing distance for a 75 inch TV is 2.3 metres away.
But rules aren't everything. We reckon this comes down to personal preference and usage. If you're a gamer, you probably already sit closer to the TV than a movie watcher would. If you're a casual viewer in the living room, you might already sit further away.
If you like a big TV then go really big straight up, don’t feel the need to conform to some mathematical formula devised in a lab, maths doesn’t know your life. Alternatively if you prefer a smaller screen TV, buy the small TV and be your small TV loving self without shame!
Wall Mounting
So the decision is made, you’ve gone out and bought a huge new TV, the old one is on its way to whichever relative likes to tinker with old TVs (we’ve all got one). The cardboard has been ripped off and all of the neighbourhood cats seem to be having a town hall meeting inside it. You proudly display the new TV...on the same old stand you had the old one on? No!
Your new TV will be the very latest of the latest technology, thinner than ever before, designed to be hung on the wall like a fine piece of art. If you’ve ever admired how sleek a mounted TV looks, you’re not alone. But beyond just aesthetic appeal, wall mounting has practical benefits that might make it the best choice for your home.
Why wall mount a TV?
Mounting your TV on the wall isn't just about looks. It can improve safety, save space, and amplify your viewing. Here's why it's worth considering:
- Wall mounting is safer for kids & pets. A properly mounted TV won’t tip over, reducing the risk of accidents and injuries.
- It saves space. Ditch the bulky TV stand and free up room for décor, storage, or a sound system.
- You'll get more viewing angles. Depending on your mount type, you can tilt or swivel your TV for the best view from anywhere in the room.
- Reduces glare. Tilting or rotating your screen can minimise reflections from windows and lights, improving picture quality.
- Wall mounted TVs look better. No visible cables running across the floor or cluttering your entertainment unit.
Our tip: Want an ultra-minimalist look? Consider concealing cables inside the wall for a seamless setup.

How to Wall Mount a TV – A Quick Guide
Installing a TV on the wall is a fairly simple and straightforward DIY. The instructions will vary from brand to brand, however the basic steps are the same.
You will need these tools:
- Wall mount kit with bracket and screws
- Drill and drill bits

- Level
- Measuring tape
- Pencil
- Stud finder
- OPTIONAL masonry drill bits and wall plugs (check if these come with the wall mount kit) if your wall is brick or concrete.
These are the steps to install:
- Check the Wall Type – If you have brick or concrete walls you need to have your masonry drill bits handy.
- Find the Studs – Use a stud finder to locate secure points for mounting (never drill into just plasterboard).

- Attach the Brackets to the TV – Secure the mount to the back of the TV using the correct screws.

Common wall mounting mistakes to avoid
These are the biggest mistakes people make when mounting a TV:
- Ignoring weight limits – Always check your wall mount's max weight capacity.
- Not measuring the viewing height – The TV centre should be at eye level when seated.
- Skipping the stud finder – Mounting into plasterboard without studs can lead to disaster.
- Messy cables – Use cable covers or wall conduits to keep things looking neat.
