That diagonal number — 42 inches — is just the screen, and it almost never tells you whether the TV will actually fit your entertainment center. One wrong measurement and a new TV becomes a return trip. Here’s the full breakdown of 42-inch TV dimensions in centimeters, what changes when you add the stand, and how much room to leave on your wall or shelf.
What The 42-Inch Measurement Actually Means
TV size is measured diagonally from one corner of the screen to the opposite corner — not the bezel, not the frame.
42-Inch TV Dimensions: Screen vs. Total Unit
The numbers that matter for fitting into a space are the total external dimensions, which include the bezel. Here’s how the three measurement types stack up:
| Measurement Type | Width (cm) | Height (cm) |
|---|---|---|
| Screen only (display) | 93.0 | 52.3 |
| Unit without stand (with bezel) | ~95.0 | ~54.3 |
| Unit with stand | ~100.6 | ~66.5 |
Depth runs about 7.6 cm (3 inches) for most models — enough to matter when you’re pushing a TV into a cabinet or flush against a wall.
How 42 Inches Compares To 43-Inch TVs
Most manufacturers shifted from 42-inch to 43-inch panels around 2020. A 43-inch TV screen is about 96.8 cm wide — nearly 1.8 cm wider than a true 42-inch display. The bezels also differ by brand, so a 43-inch set from Samsung or LG may not fit the same footprint as an older 42-inch model. Always measure your space and the specific model’s specs, not just the diagonal.
VESA Mounting And The Stand Factor
42-inch TVs typically use a VESA 200×200 mm mounting pattern. That’s a standard mount, easy to find at any retailer. Before buying a wall mount, check the TV’s weight (usually 10–15 kg for this size) and confirm the mount rating. When using the stand, remember the total height jumps to 66.5 cm — that extra 12 cm matters if the TV sits on a low cabinet.
Ideal Viewing Distance For A 42-Inch TV
Where you sit changes how the picture looks. The best distance depends on the resolution:
| Resolution | Recommended Viewing Distance | Notes |
|---|---|---|
| 4K Ultra HD | 1.3–1.7 meters (4.2–5.6 feet) | Shorter for immersive detail |
| Full HD (1080p) | ~1.42 meters (4.6 feet) | Center of screen at eye level |
Mount the TV so the screen’s center sits roughly 1 meter (39 inches) from the floor for eye-level viewing while seated. For a 42-inch TV placed on a stand, the center of the screen will be higher — adjust your seating height accordingly.
Common Measuring Mistakes To Avoid
Three errors trip up most buyers. First, using the screen width (93 cm) as the total width — the bezel adds about 2 cm on each side. Second, ignoring the stand’s footprint; a TV with stand is 100.6 cm wide and 66.5 cm tall, not the 95 x 54.3 cm a cabinet measurement would expect. Third, assuming a 42-inch and 43-inch TV are the same — that extra 1.8 cm of width can make or break a tight fit.

Getting The TV Fitted: Wall Or Stand Checklist
Before buying, confirm these three things: the TV’s total width (including bezel) is at least 2 cm narrower than your cabinet opening, the mount points match VESA 200×200, and there’s 7–10 cm of depth clearance for cables and airflow. A TV that looks right on paper can still be a squeeze in real life — measure twice, buy once.
FAQs
Does a 42-inch TV fit on a standard 36-inch stand?
Usually not. The TV unit alone is about 95 cm (37.4 inches) wide without the stand, which is already wider than a 36-inch (91 cm) stand.
Is a 42-inch TV the same size as a 43-inch TV?
No. A 43-inch TV screen is about 96.8 cm wide, roughly 1.8 cm wider than a 42-inch screen. The bezels also differ between brands, so the total unit width can vary more than the diagonal suggests. Always check the exact model dimensions before buying a cabinet or mount.
Can I wall-mount a 42-inch TV myself?
Yes, with the right mount and tools. The VESA 200×200 pattern is standard and easy to install. You’ll need a stud finder, a level, and a drill — plus a helper to lift the TV (most 42-inch models weigh 10–15 kg). If you’re not comfortable, a professional installation costs about $100–$150.
Why do manufacturers sell 43-inch instead of 42-inch now?
Panel production shifted to the 43-inch size around 2020 as glass-cutting efficiency improved at LCD factories. The 42-inch size still exists for some specialty models and older stock, but most major brands (Samsung, LG, Sony) now primarily offer 43-inch TVs.
How much space do I need behind a 42-inch TV for cables?
At least 7–10 cm (3–4 inches) of clearance from the wall to the back of the TV. Most 42-inch models are about 7.6 cm deep, but cable connectors can add another 2–3 cm. For a flush wall mount, use recessed outlets or a low-profile cable management kit.
