Do you need help finding the perfect TV size for your 12×12 room? Don’t worry. We’ve got you covered.
Luckily, the organizations like SMPTE have viewing distance tables & formulas for TV sizes, which we can use to find the right TV size for any room size.
And the process is really simple, just 3 steps! But I have for you a pro tip first.
Different Organizations like SMPTE, THX and Panasonic recommend different TV sizes for the same viewing distances. But let me make it easy for you, THX viewing distances are for Home theater setup for an immersive experience for 4k TVs. SMPTE & Panasonic recommendations are for mixed and casual usage in the living room for both 4k & 1080p TVs.
Finding Right TV Size for 12×12 Living Room
1- First, plan your room layout and furniture placement, and identify the TV location and seating place.
2- With a measuring tape, measure the distance from your TV location (wall or stand) and seating place (couch or bed).
For instance, I planned my room layout and furniture in a way that the distance between the TV location and the sofa was 7 feet.
3- Now divide your available viewing distance (mine was 84 inches) by 1.6235 using the SMPTE formula. Or Panasonic formula. The answer will be your recommended TV size. You can also get the TV size from the table below for your viewing distance.
1-SMPTE Viewing Distance Formula
Viewing Distance in (inches)/ 1.6235= TV Size (inches)
84 inches/ 1.6235= 51 Inches (Recommended TV Size 50 Inches)
2- Panasonic Viewing Distance Formula
Viewing Distance in (inches)/ 1.5= TV Size (inches)
84 inches/ 1.5= 56 Inches (Recommended TV Size 55 Inches)
Note: After dividing your viewing distance, if you get a TV size like 51 inches or 56 inches which may not be available on the market, you should buy the closest TV size like 50-inches or 55 inches TV. You can confirm this from the table, which lists Viewing Distances for popular TV sizes that are available in the market.

Recommended TV Size For 12×12 Sq. feet Living Room
In my experience, no matter how you plan your room layout and furniture placement, you can maintain 7-8.1 feet distance. So, you can go for 50 to 55 inches TV. The key is to measure the distance from the TV Stand/wall location to your front couch and choose the TV size according to your viewing distance from the TV. Select 50-inch TV for 7 feet viewing distance and 65-inch TV size for 8-9 feet viewing distance.
But if your room does not allow you to maintain 8.1-9.1 feet distance, then 65-inch TV will be too big for you.

How to Find the Right TV Size for 12×12 Home Theater Room
1- First, plan your room home theater layout with 2 rows or 1-row seats as you want.
2- Take a measuring tape and measure the distance between your TV location and first row in inches. For instance, in my case it was (96 inches) 8 feet.
3-Look at the THX distance table for the home theater setup, which is best for movies. Or use the THX formula.
TV Size= Viewing Distances inches x 0.835
For instance, in my case viewing distance between TV location and seat is 96 inches. So,
TV Size (inches)=96 inches x 0.835= 80 inches TV
So for a 12×12 home theater room, you can go for a 80-inches TV if you can maintain 8 feet distance from the TV to first row and adjust row of seats. You can go for bigger TV sizes if you can maintain more than 8 inches. In any case, plan your home theater room layout with seating rows first, then measure the viewing distance and choose the TV size according to THX recommended viewing distances.
|THX Viewing Distance Inches||THX View Distances(feet)||TV size|
|38 inches||3.2 feet||32-inch|

Key Factors That Determine the Right TV Size For Your Room
1-Your room layout & furniture placement
Your room layout planning and furniture placement will decide where you will install the TV and how much viewing distance you will have from your TV location to your sitting place. In home theater setup, seat size and number of rows will decide how much distance will be left for you from your TV.
2-Optimal Viewing Distance For TV Size
For the best viewing experience, we need to be at a specific distance from the screen. SMPTE, Panasonic and THX have given some simple formulas to calculate the viewing distance for your TV. We will use these formulas to determine the TV size for our room.
1–SMPTE Formula For Mixed Usage in Living Room/Bedroom (1080p & 4k TVs)
TV Size (Diagonal)= Viewing Distance inches/ 1.6
2-Panasonic Recommended Formula For Mixed Usage in Living/Bedroom (1080p & 4k TVs)
TV Size (Diagonal)= Viewing Distance/ 1.5
3-THX Formula For Watching Movies in Home Theatre (4K TVs)
TV Size Diagonal = Viewing Distance inches /1.2
3-Personal Preferences (including Budget)
As always, what matters the most is you. Your preferences, your experiences and your budget. You may prefer to sit closer to the TV or farther, depending on your experience. You can go for a 50, 55 or 65-inch TV based on your budget or liking.
