What Size TV Unit Do You Need for a 75" or 85" TV? A Sizing Guide

Improving your home entertainment center setup is an amazing experience. Owning an huge, movie-theater like screen dramatically changes the experience of watching films, streaming television series and playing video games. But when the initial thrill fades away, there comes a very practical yet extremely important question - how big should the size tv unit for a 75 inch tv be? If you wanted to take it one step further, then what would be the appropriate size tv unit for 85 inch tv?

This is a very frequent occurrence. The buyer purchases an excellent quality TV and puts it onto a small and insignificant cabinet which makes everything look messy and uncoordinated. Balanced sizes of objects are key to creating a designer interior at home. 

If you happen to be wondering about what size of a television unit is required to fit such large televisions, then you are at the right place. This guide provides you with detailed information on dimensions, visual symmetry of the space you are decorating, and choosing the perfect TV cabinet for transforming your living room into a state-of-the-art theater.

1. The Diagonal Measurement Trap 

However, before we move on to discuss which size tv unit for 75 inch tv is suitable, it is important that we understand how televisions are measured. A common misunderstanding among  buyers is that if they have a 75 inch TV, then their TV will measure 75 inches in width from side to side.

The truth is that TVs are measured diagonally from top to bottom across opposite corners of the set. This means that the width of the screen itself is actually much shorter than the number on the package. If you want to know how big the TV unit is, you will need to work only based on the actual width of the device.

A regular 75 inch TV would measure around 167 centimeters in width.

An 85 inch TV would measure around 189 centimeters in width.

With this information at hand, we can start using interior design principles to determine exactly how big a TV unit should be in order to create balance within our living room.

2. How Big Should a TV Unit Be? The Golden Rules 

As soon as the decorators and interior designers are questioned about the size of the tv unit, they invariably bring up the subject of balanced. And the fundamental law of all media cabinets is: your furniture should be bigger in width than the screen.

In case you choose a TV set which is bigger than your cabinet, your living room furniture will seem very top-heavy. There is going to be a certain visual imbalance, like something may fall out of it any moment. You have to make sure that the sides of your cabinet are expanding beyond the edges of your TV screen.

The ideal gap between the TV screen and the sides of your cabinet is somewhere around 10 to 15 cm. Such a "framing" for your screen will make the second feel more grounded. What is more, the gap is the best place for decoration, whether it is a tall vase, a framed photo or bookshelf speakers.

3. What Size TV Unit for 75 Inch TV? 

Since this is probably one of the most demanded sizes of televisions available in the market, questions about the right size of TV units for 75 inch TVs pop up all the time. As was already mentioned, the actual width of this kind of screen amounts to 167 cm.

If you are concerned with what size tv unit for 75 inch tv will be enough in order to guarantee the maximum clearance between the two, then your best bet would be getting a unit measuring 180 cm. In this case, you will have around 6 cm left on each side, but this is already a rather tight configuration that looks quite blocky and hardly leaves some room for decorations.

The recommendation by professional interior decorators regarding the ideal size of a unit that goes under a 75-inch TV is 200-210 cm. This will guarantee perfect balance between furniture pieces and will give you over 20 cm of clearance space to the left and to the right.

If, for instance, you have a large and huge place to live, and you wish to know the appropriate dimensions of a TV stand for a 75 inch TV that will give a luxurious feeling, then you can buy the one that will stretch as much as possible, extending to about 240 cm. When you make use of a too long console on a 75-inch screen, you will get a very fashionable feeling along with a lot of room to store things from your house.

5. What Size TV Unit for 85 Inch TV? 

In case you’ve made that plunge into proper home theater, then your dimensions will shift. An 85-inch television is a giant piece of equipment. Measuring around 189 cm in real life, it towers over the wall that supports it.

So, what size TV unit for an 85-inch TV do you need to maintain elegance in your living room?

The smallest dimension you can think about is a cabinet measuring 200 cm. This way, you’ll have around 5 cm on both sides. But when dealing with such a large screen, 200 cm might seem insufficient. It will overpower the furniture below it and make buying a classy cabinet pointless.

The best solution regarding the question of what size tv unit for 85 inch tv will yield the best results would be between 220 cm and 240 cm. The overhang of the unit that measures 240 cm will be slightly above 25 cm on both sides. 

Such a long base holds the huge black rectangle screen, forming a beautiful architectural element of the interior. A low and long 240 cm TV unit is the hallmark of luxurious modern interiors where it perfectly blends with an 85-inch screen and offers enough storage space.

6. Height and Depth Considerations 

Although the length is the most important aspect to consider while trying to determine how big your tv unit should be, one should not forget about its height and depth. It goes without saying that these factors influence comfort and the size of space left for other things.

• Correct Height
  A correct height ensures that your neck does not suffer from tension. As soon as you are comfortably seated on your sofa, the TV set in front of you should be at your eye level. 
  Since both 75-inch and 85-inch models are quite large, putting such a TV on a high cabinet would require you to bend your head upwards. The result is the same as looking at something for too long; the head begins to ache. You need to buy cabinets whose height ranges from 40cm to 50cm.
• The Correct Depth
  Just because you have a large screen doesn’t mean that you have to have a cabinet that’s very deep. In fact, if your space is rather narrow, then you don’t want a very deep cabinet since it will hinder your ability to walk around. It’s better to have a cabinet with a depth of about 40cm to 45cm.

7.Perfecting Your Setup with the Right Style and Height

Choosing the right width for your 75-inch or 85-inch screen is a massive step, but making sure that your newly purchased furniture fits the overall aesthetic of your house is equally important. Your media console is a central design element that anchors your entire living room, and its design needs to reflect your personal taste.

9. Frequently Asked Questions (FAQ) 

1. What size TV unit for a 75-inch TV is the very best selection?
   As the exact width of a 75-inch television is about 167cm, the very best decision will be to choose a cabinet from 200cm up to 210cm in size. In such a way, there will be a wonderful overhang on both sides ranging from 15cm up to 20cm, which guarantees the perfect balance of the entire picture.

2. What size TV unit for an 85-inch TV would be ideal?
   A screen of 85 inches is about 189cm in width. To mount such a huge screen, you need to search for a cabinet no smaller than 220cm. To have the most luxurious and expensive design of a media console, we recommend choosing a cabinet measuring 240cm.

3. What size should I aim for when comparing a cabinet to the TV itself?
   In terms of interior design rules, one thing you should absolutely keep in mind is that your cabinet must be wider than your TV. The optimal scenario would be where your piece of furniture protrudes around 10 to 15 centimeters to each side of your TV set in order to create a visually strong base.

4. Should I consider getting a wider cabinet if my TV is mounted to the wall?
   Indeed, even when it comes to mounting your TV onto the wall, this rule applies. Mounting a 75-inch TV above a small 120cm cabinet will make the room look quite unbalanced to say the least. No matter whether you use a wall bracket or the TV stand provided by the manufacturer, always follow the rules regarding dimensions.
