Every week we get called to mount a TV that’s either too small for the room or comically too big. Both are problems, and both are avoidable with a quick calculation before you buy. Here’s how to choose the right TV size for your living room, with specific examples for common DFW home layouts.
The Quick Answer
Measure the distance from where you’ll sit to where the TV will go, in inches. Divide by 1.2. That’s your ideal TV size for mixed-use viewing. Divide by 1.0 if you mostly watch movies and want an immersive experience.
Examples:
- 8 feet (96”) from couch to TV → 80” TV for movies, 80”+ for mixed use
- 10 feet (120”) from couch to TV → 100” ideal for movies, but realistically 85” TV
- 12 feet (144”) from couch to TV → 120” ideal, realistically 98” TV
These numbers are bigger than what most people assume. The average living room TV in DFW is 55”–65”, and in almost every home we visit, that TV is too small for the viewing distance.
Why Most TVs Are Too Small
The old “you need to sit X feet away from a TV or it’ll hurt your eyes” advice is wrong. It was based on CRT tube TVs from the 1990s with terrible resolution. Modern 4K TVs have so many pixels that you can sit close without seeing individual pixels — the problem now is sitting too far away and losing detail.
SMPTE (Society of Motion Picture and Television Engineers) recommends a 30-degree viewing angle for a cinema experience. THX recommends 36 degrees. Both translate to much larger TVs than most people buy.
DFW Home Examples
Townhome / Apartment Living Room (10’–11’ viewing distance)
Common DFW townhome builds from DR Horton, Lennar, and Bloomfield typically have living rooms where the couch sits 10–11 feet from the TV wall.
Recommendation: 75”–85” TV. The 85” Samsung, Sony, or LG models in this range start around $1,800 and are the sweet spot for this room size.
Standard Suburban Family Room (11’–13’ viewing distance)
Most single-family homes in Garland, Rowlett, Plano, and Richardson have family rooms with 11–13 feet between the primary seating and the TV wall. Often there’s a fireplace involved.
Recommendation: 85”–98” TV. If you have the wall space, 98” is increasingly affordable — TCL and Hisense 98” models start around $2,200, and the viewing experience is significantly better than an 85”.
Large Open-Concept Great Room (13’–18’ viewing distance)
Custom homes in Heath, Rockwall, Frisco, and Prosper often have great rooms with vaulted ceilings and 15’+ distance to the TV.
Recommendation: 98” minimum. For rooms 15’+, consider a short-throw laser projector with a 100”–150” ambient-light-rejection screen. Projectors like the Formovie Theater, AWOL LTV-3500, or Samsung Premiere start around $3,000–$6,000 and give you a true cinema-size image.
Bonus Room Converted to Media Room (10’–14’ viewing distance)
Bonus rooms above the garage — common in DFW homes built 2005–present — are often the best home theater spaces because they can be darkened and have fewer windows.
Recommendation: 98” TV or dedicated projector setup. These rooms often benefit most from a full surround sound system since noise isolation is good.
Mounting Height Matters
A correctly sized TV mounted at the wrong height still looks wrong. The center of the screen should be roughly at eye level when you’re seated — usually 42”–48” from the floor for standard couch heights. The typical mistake is mounting the TV too high (often over a fireplace), which looks good in listing photos but creates neck strain for daily viewing.
If you must mount over a fireplace, use a pull-down mount or articulating mount that lets the TV angle down to a reasonable viewing position.
Common Mistakes
Buying a small TV because “the room isn’t that big.” Room size isn’t the constraint — viewing distance is. A small living room with a 9-foot viewing distance still calls for a 75” TV.
Mounting above the fireplace. Almost always too high. If the fireplace is the only option, use an articulating mount.
Choosing brand over panel type. For 2026, OLED (LG, Sony) and QD-OLED (Samsung, Sony) are the top tier. Mini-LED (Samsung Neo QLED, Sony Bravia XR, TCL QM series, Hisense U series) is the sweet spot for bright rooms. Standard LED is fine but increasingly outdated for anything over 65”.
Underspending on sound. A $3,000 TV with the built-in speakers sounds worse than a $1,500 TV paired with a $400 soundbar. If budget is tight, prioritize a good soundbar or basic 2.1 system over a bigger TV.
Bottom Line
For most living rooms in Garland and the DFW area, you should be looking at 85” or larger. The price gap between 75” and 85” is usually $300–$500, and the gap between 85” and 98” has closed dramatically in the last two years. Bigger TVs are cheaper than ever, and the viewing distance math almost always supports going larger.
