TV Size & Viewing Distance Calculator

Go either way: enter a screen size for the ideal seating distance, or a seating distance for the screen size that fills your view — tuned for 4K or 1080p.

Size the screen to the seat

The right TV isn’t the biggest one on the shelf — it’s the one that fills your field of view from where you sit without showing its own pixels. Resolution changes the maths: 4K lets you sit closer or go bigger, while 1080p wants a little more distance. Get the pairing right and a mid-sized set can feel more cinematic than a giant one placed wrong.

Frequently Asked Questions

How far should I sit from a 4K TV?

Closer than you'd think. Because 4K packs four times the pixels of 1080p, you can sit roughly 1 to 1.5 times the screen's diagonal away before the image starts to look soft — so a 65-inch 4K set is comfortable from about 5.5 to 8 feet, with the sweet spot near 6.5 feet. Sitting that close is what makes a big 4K screen feel immersive rather than just large.

Why is the recommended distance different for 1080p?

With fewer pixels, a 1080p screen shows visible structure — the gaps between pixels — if you sit too close, so the comfortable range is farther back, about 1.5 to 2.5 times the diagonal. That's why upgrading to 4K often lets you either move the couch closer or buy a bigger screen for the same seat without the picture breaking down.

Should I just buy the biggest TV that fits?

Bigger is usually better for immersion, but only up to the point where you can take in the whole frame comfortably and the source holds up. Switch this tool to 'TV size for a seating distance' and it recommends the largest diagonal you can fill at 4K or 1080p from where you actually sit. Pushing well past that can strain your eyes and expose low-resolution content.

Do these numbers account for how I use the TV?

They're based on common SMPTE/THX-style viewing-angle guidance for a mix of movies and general watching. Preferences vary — cinephiles often sit closer for a fuller field of view, while a TV that's also a casual background screen might sit farther back. Use the range as a guide and trust your own eyes, especially if you wear glasses or watch a lot of lower-resolution content.
