Buying a TV feels easy until the tape measure comes out and reality hits. Suddenly, “Will it fit?” becomes the main character. That’s exactly why people obsess over 45 inch TV dimensions. On paper, 45 inches sounds polite and manageable. In real life, it can dominate a wall, bully a TV stand, or flirt dangerously with your bookshelf. The diagonal number on the box doesn’t tell the full story, and guessing usually ends in regret. This guide exists to save you from awkward returns, crooked wall mounts, and that moment when you realize the TV is wider than the furniture meant to hold it. Let’s measure before we panic.
What Does “45 Inches” Really Mean on a TV?
Let’s start with the truth most buyers learn too late.
A 45 inch TV size refers only to the diagonal measurement of the screen, measured corner to corner. It does not describe the width, height, or depth of the TV.
That diagonal measurement comes from old television standards, and while it’s still used today, it’s also misleading if you’re planning space.
In real life, width and height matter far more than the diagonal number.
TV Diagonal Measurement Explained (Without the Confusion)
Almost every modern television uses a 16:9 aspect ratio. That ratio determines how wide and tall the screen becomes once you know the diagonal length.
Because of that ratio:
- A 45 inch screen becomes much wider than most people expect
- The frame and stand add extra size beyond the screen itself
- Two TVs labeled “45 inch” can still differ slightly in overall size
This is why buyers ask:
- how wide is a 45 inch TV
- difference between screen size and TV size
- how to measure a TV correctly
45 Inch TV Dimensions (Width, Height, and Depth)
Here are the real
world averages you can expect from most brands.
45 Inch TV Dimensions in Inches
| Measurement | Size |
|---|---|
| Screen width | 39.2 inches |
| Screen height | 22.1 inches |
| TV height with stand | 24–25 inches |
| TV depth without stand | 2.2–2.8 inches |
| TV depth with stand | 8–10 inches |
These numbers reflect common LED and OLED models currently on the market.
45 Inch TV Dimensions in CM
If you measure in metric units, here’s the same data converted accurately.
| Measurement | Size |
|---|---|
| Screen width | 99.6 cm |
| Screen height | 56.1 cm |
| Height with stand | 61–64 cm |
| Depth without stand | 5.5–7.1 cm |
| Depth with stand | 20–25 cm |
Small variations happen between brands, mostly due to bezel thickness and stand design.
How Wide Is a 45 Inch TV in Real Life?
This is the measurement that causes the most trouble.
The 45 inch TV width is about 39 inches for the screen alone, but once you include the frame, most TVs end up closer to 39.5 to 40 inches wide.
That extra half inch matters if:
- Your TV stand is narrow
- You’re placing the TV between shelves
- You’re mounting it in a tight wall space
Always measure the space first. Eyeballing it leads to regret.
Screen vs Frame Dimensions (Why Bezels Matter)
Even “bezel less” TVs still have frames.
Typical bezels add:
- 0.3–0.6 inches to each side
- Slightly more at the bottom
That’s why screen size and TV size are not the same thing, and why measuring space before buying a TV is essential.
45 Inch TV Height: With Stand vs Without Stand
Height is where many buyers get surprised.
- 45 inch TV height without stand: 22 inches
- 45 inch TV height with stand: 24–25 inches
That extra height comes from the base, not the screen.
If your cabinet has shelves above it, this difference can make or break the fit.
Does the Stand Add Height to a TV?
Yes. Always.
Most stands add 2–3 inches of height. Some pedestal style bases add even more.
If vertical space is tight, always check:
- 45 inch TV dimensions without stand
- 45 inch TV dimensions with stand
Never assume they’re the same.
45 Inch TV Depth (Why “Slim” Isn’t Always Slim Enough)
Modern TVs look ultra thin from the side, but depth still matters.
Without Stand
- Around 2.2–2.8 inches
- OLED models are usually thinner than LED
With Stand
- Around 8–10 inches
- Depends on foot spacing and base design
This matters a lot for shallow TV cabinets and floating shelves.
45 Inch TV Dimensions With Stand vs Without Stand
Here’s a quick comparison that answers most fit questions instantly.
| Setup | Width | Height | Depth |
|---|---|---|---|
| Without stand | 39.2 in | 22.1 in | 2.5 in |
| With stand | 39.5–40 in | 24–25 in | 8–10 in |
If you’re wondering will a 45 inch TV fit on my stand, this table is your shortcut.
45 Inch TV Stand Width Requirement
A TV should never sit edge to edge on a cabinet.
Safe minimum stand width:
42–45 inches
This gives stability, visual balance, and room for accessories like soundbars.
Weight of a 45 Inch TV
Weight matters more than people expect, especially for wall mounting.
Average Weight
- Without stand: 22–26 lbs (10–12 kg)
- With stand: 25–30 lbs (11–14 kg)
Always check your mount’s rating and your drywall TV mount weight limit before installing.
Can a 45 Inch TV Be Wall Mounted?
Yes. Easily.
Most models support standard VESA mounting patterns, commonly:
- 200 × 200 mm
- 300 × 300 mm
45 Inch TV Wall Mount Size Tips
- Choose a mount rated for 40 lbs or more
- Leave 2–3 inches behind the TV for cables
- Mount at eye level for comfort
Eye Level TV Mounting Height (What Feels Right)
For most seating positions, the center of the screen should sit 42–48 inches from the floor.
This keeps your neck relaxed and makes long viewing sessions comfortable.
How Much Space Does a 45 Inch TV Need?
The TV itself isn’t the whole story.
Recommended Clearance
- Sides: 1–2 inches
- Top: 2 inches
- Back: 2–3 inches
This improves airflow and makes cable management easier.
Ideal Viewing Distance for a 45 Inch TV
Resolution changes how far you should sit.
- 4K TVs: 5.5–7.5 feet
- 1080p TVs: 7–9 feet
That makes a 45 inch TV a strong choice for bedrooms, apartments, and small living rooms.
Transporting and Moving a 45 Inch TV
It’s manageable, but still fragile.
Typical Box Size
- Width: 43–45 inches
- Height: 28 inches
- Depth: 6–8 inches
Will it fit in a sedan?
Sometimes. But it’s risky.
Keeping the original box makes moving far safer.
45 Inch TV vs Nearby Sizes
43 Inch vs 45 Inch TV
- Slightly wider screen
- More immersive for sports and gaming

45 Inch vs 50 Inch TV

This size works best if:
- Seating distance is under 8 feet
