TV Size Guide: How Big Should Your TV Be?

Updated January 2026 · 6 min read

The most common mistake people make when buying a TV? Going too small. After living with a TV for a few months, almost everyone wishes they'd gone bigger. But how do you know what size is right for your space?

This guide gives you practical recommendations based on your viewing distance and room setup.

The Simple Rule

Quick Formula: Divide your viewing distance (in inches) by 1.5 to get the minimum recommended TV size. For a more immersive experience, divide by 1.2.

For example, if you sit 9 feet (108 inches) from your TV:

Viewing Distance Recommendations

Viewing Distance Minimum Size Recommended Size Immersive Size
5 feet 40" 50" 55"
6 feet 48" 55" 65"
7 feet 55" 65" 75"
8 feet 65" 75" 83"
9 feet 75" 77" 85"
10 feet 77" 83" 85-98"
12 feet 85" 98" 98-115"

Why Bigger is Usually Better

With 4K resolution, you can sit much closer to a TV without seeing pixels than with older 1080p sets. This means you can go bigger without the picture looking grainy.

A larger screen is more immersive - it fills more of your field of view, making movies and games more engaging. And with TV prices falling, the price-per-inch of larger TVs is better than ever.

When to Consider a Smaller TV

While we generally recommend going bigger, there are some situations where a smaller TV makes sense:

Size vs Quality Trade-offs

If your budget is fixed, should you get a larger budget TV or a smaller premium TV? Here's how to think about it:

Our take: For most people, a 65" good TV beats a 55" great TV. Screen size has the biggest impact on day-to-day viewing enjoyment.

Common Upgrade Paths

Here are the most popular size upgrades and what to expect:

55" to 65" (+18% diagonal, +39% screen area)

A noticeable but modest upgrade. Worth it if you're already considering replacing your TV.

55" to 75" (+36% diagonal, +86% screen area)

A dramatic difference. This is often the sweet spot for living room upgrades.

65" to 77" (+18% diagonal, +40% screen area)

The most common upgrade for people who already have a large TV. The jump to 77" feels significant.

65" to 85" (+31% diagonal, +71% screen area)

A major upgrade that transforms your viewing experience. Make sure you have the wall space and viewing distance.

Will It Fit?

Before buying, measure your space. Here are the actual dimensions (width x height) of common TV sizes:

TV Size Width Height
55" 48.5" 27.5"
65" 57" 32.5"
75" 66" 37.5"
77" 67.5" 38.5"
83" 73" 41.5"
85" 75" 42.5"

Also consider: Will it fit through your door? Large TVs (77"+) can be tricky to maneuver through hallways and doorways. Check the box dimensions before purchase.

The Bottom Line

When in doubt, go bigger. The most common regret is buying too small. Use the viewing distance chart as a starting point, then factor in your room layout, budget, and preferences.

A 65" TV is the most popular size for a reason - it's big enough for most living rooms without being overwhelming. But if your viewing distance is 8+ feet, seriously consider jumping to 75" or larger.
