A 46-inch TV measures roughly 40.9 inches wide by 23.4 inches tall for the screen alone, with a total width of about 43.3 inches when you include the stand.
Grab a tape measure and check that spot in your entertainment center. A 46-inch TV sounds big, but the actual screen width is about 41 inches — roughly the width of two standard guitars laid end to end. The “46 inches” is the diagonal corner-to-corner measurement, not the width. Mistaking that number is the most common reason a “fits in the cart” TV jams against the cabinet walls during setup. Here is what you actually need to know to get the fit right, whether you are buying an old used unit or fitting a modern replacement into the same space.
The Exact Dimensions You Need
A 46-inch TV with a standard 16:9 aspect ratio delivers these baseline screen measurements. Add the bezel and stand and the footprint expands.
- Screen width: 40.9 inches (103.8 cm) — this is the glass, not the frame.
- Screen height: 23.4 inches (59.3 cm).
- Total unit width with stand: typically 43.3 inches — the 2.4-inch difference is the bezel.
- Unit depth with stand: 3.0 to 4.7 inches, depending on the stand’s angle and the chassis design.
- Weight: roughly 67.5 lbs (30.6 kg). Wall mounts need an 80-lb rating minimum.
- VESA mount pattern: 200×200 mm. A universal mount may fit, but confirm before drilling.
These numbers shift slightly between manufacturers. A Samsung 46-inch model from 2011 has a different bezel thickness than an LG from the same era. The 43.3-inch total width figure is your safe planning number for any standard 46-inch set.
Is The 46-Inch Size Still Available In 2026?
No major US manufacturer currently produces a 46-inch TV. The size has been discontinued and replaced by 43-inch and 48-inch models that match modern panel-cutting economics. If you search for a new 46-inch TV in 2026, you will find zero results from Samsung, LG, Sony, TCL, or Vizio. The 46-inch class was common through roughly 2012, and most units on the secondary market today are 1080p (Full HD) LED sets from that era, not 4K.
If you own a 46-inch TV and it still works, treat it well — it is a legacy size. If you are shopping for a used one, expect original retail prices (2010–2012) in the $1,200–$2,000 range, with current resale value sitting around $150–$300 depending on condition and features.
For anyone looking to buy new today, the smart move is comparing a 43-inch or 48-inch replacement. Our roundup of the best modern alternatives covers the specific models that fit the same footprint while delivering 4K resolution and current smart features.
Correct Viewing Distance For A 46-Inch Screen
The right distance depends on the content you watch most. Most legacy 46-inch TVs are 1080p, not 4K, so the rule shifts accordingly.
- For 1080p content: sit 6 to 7.5 feet away. Closer than 6 feet and you will see individual pixels on text and fine detail.
- For 4K content (if you have a rare 4K 46-inch import): sit 4.6 to 6.1 feet away. The higher pixel density lets you sit closer without visible pixelation.
- Screen center height: the center of the screen should be at seated eye level, typically 40–42 inches from the floor. For a 23.4-inch tall screen, that means the bottom edge sits roughly 28–29 inches off the ground.
Don’t confuse “46-inch diagonal” with “46-inch wide.” A 46-inch TV is about 41 inches wide. That width clears a 44-inch cabinet opening with a couple of inches of breathing room on each side.
What To Check Before You Buy Used Or Fit A Replacement
Measure three things before you commit: the opening width of your entertainment center, the depth from front to back wall (accounting for cables and power plug clearance), and the VESA pattern on the back of the unit. A 200×200 mm pattern is standard for most 46-inch TVs, but some Sony and early Samsung models use 400×400 or VESA 300×300 — verifying before you buy a wall mount saves a trip to the hardware store.
Power draw on legacy 46-inch LED units runs 120W–150W during normal use. Modern 43-inch and 48-inch replacements draw similar power but offer better efficiency and 4K resolution. If power cost or picture quality matters, a current-model replacement pays for itself over a few years of daily use.
FAQs
Will a 46-inch TV fit where my old 42-inch TV sat?
Not automatically. A 46-inch screen is about 3 inches wider and 2 inches taller than a 42-inch. Measure the opening width of your cabinet — you need at least 43.3 inches of clear horizontal space to accommodate the stand.
Can I mount a 46-inch TV on any VESA wall mount?
Only if the mount supports 200×200 mm spacing. Many universal mounts do, but budget or older fixed mounts may only support smaller patterns. Check the mount’s spec sheet before drilling. The TV weighs roughly 67.5 lbs, so the mount must be rated for at least 80 lbs.
Does a 46-inch TV support 4K?
Most 46-inch TVs sold in the US are 1080p (Full HD) models from the 2009–2012 era. A small number of niche 4K 46-inch imports exist, but they are rare. If a used listing claims “4K,” verify the model number on the manufacturer’s support page before buying.
