Video Resolutions Explained: The Complete List
From 144p to 8K — every standard video resolution, its exact dimensions in pixels, and when you should use it. This is the full list of video resolutions, from 540p to 720p to 1080p to 4K, explained in plain English.
Which resolution should you use?
| Exporting for | Use | Why |
|---|---|---|
| YouTube / streaming | 1080p | The standard for most content — 1920 × 1080 |
| Reels / TikTok / Shorts | 1080 × 1920 | The recommended vertical (9:16) tier |
| Instagram feed | 1080 × 1080 | Square 1:1 feed posts |
| 4K TVs / archiving | 2160p | Four times the pixels of 1080p — 3840 × 2160 |
| Slow connections | 540p or 720p | YouTube's lower streaming tiers |
Resolution is a ceiling, not a promise — scaling a 720p file up to 4K does not add detail that was never recorded. Every standard size is in the complete list.
What is video resolution?
Video resolutionis the size of a video frame measured in pixels — width × height. A 1280×720 video is 1,280 pixels wide and 720 pixels tall. Higher resolution means more detail, sharper text, and larger files. Resolution is written either by height (720p, 1080p — the “p” means progressive scan) or by width (4K ≈ 4,000 pixels wide).

What is 540p resolution?
540p is a video resolution with dimensions of 960×540 pixels — 960 pixels wide and 540 pixels tall — for a total of 518,400 pixels(about 0.52 megapixels). The number refers to the 540 horizontal lines of vertical resolution. If you're wondering about 540p resolution size: the frame is 960 pixels wide by 540 tall, roughly half a megapixel per frame, and a 540p video typically streams at around 1 Mbps.
You'll most often encounter 540p as a streaming quality option on YouTube, where it sits between 480p and 720p. It's also exactly one quarter of 1080p: if you divide both dimensions of 1080p (1920×1080) in half, you get 960×540. Because it sits below the 720-line threshold, 540p is not considered High Definition.
540p vs 720p: which is better?
720p is noticeably better. 720p (1280×720) has 921,600 pixels — 1.78× more pixels than 540p (960×540, 518,400 pixels). On a phone screen the difference is subtle, but on a monitor or TV, 540p looks visibly softer and more pixelated, especially in text and fine detail. 720p is the minimum resolution that qualifies as HD; 540p is not.
What is 720p resolution? Dimensions & pixel count
720p — also called HD or HD Ready — has dimensions of 1280×720 pixels: 1,280 pixels wide and 720 pixels tall in a 16:9 aspect ratio. That works out to 921,600 total pixels (about 0.92 megapixels). Put simply, the 720p height and width are 720 pixels tall by 1,280 pixels wide — the 720p width is 1,280 and the height is 720.
How big is 720p compared to 1080p? 720p has 44.4% of the pixels of 1080p(921,600 ÷ 2,073,600) — slightly less than half. Flip it around: 1080p has 2.25× the pixels of 720p. And what's below 720p? The next steps down are 540p (960×540), then 480p (854×480, DVD quality), then 360p (640×360) — which is roughly half of 720p in each dimension.
The “720” is the number of horizontal lines stacked vertically, and the “p” stands for progressive scan. 720p is the entry point for High Definition — anything below it (480p, 540p) is considered Standard Definition territory. It's still widely used for streaming on slower connections and for live broadcasts.

Standard video resolutions: the complete list
Here is every standard video resolution from 144p to 8K, with exact dimensions and pixel counts. This is the full reference list used across YouTube, streaming services, cameras, and monitors:
| Resolution | Dimensions (W×H) | Total Pixels | Megapixels | Notes |
|---|---|---|---|---|
| 144p | 256×144 | 36,864 | 0.04 MP | YouTube's absolute lowest tier; text is barely readable |
| 240p | 426×240 | 102,240 | 0.10 MP | Lowest usable tier; common on very slow connections |
| 360p | 640×360 | 230,400 | 0.23 MP | YouTube's standard low-quality tier; half of 720p |
| 480p (SD) | 854×480 | 409,920 | 0.41 MP | Standard Definition; DVD-quality |
| 540p | 960×540 | 518,400 | 0.52 MP | Quarter of 1080p; YouTube's middle streaming tier |
| 720p (HD) | 1280×720 | 921,600 | 0.92 MP | HD Ready; entry point for High Definition |
| 1080p (Full HD) | 1920×1080 | 2,073,600 | 2.07 MP | Standard for YouTube, streaming, most content |
| 1440p (QHD) | 2560×1440 | 3,686,400 | 3.69 MP | Quad HD; common for gaming monitors |
| 2160p (4K UHD) | 3840×2160 | 8,294,400 | 8.29 MP | 4× pixels of 1080p; standard for 4K TVs |
| 4K DCI (Cinema) | 4096×2160 | 8,847,360 | 8.85 MP | Cinema 4K; slightly wider than consumer 4K UHD |
| 8K UHD | 7680×4320 | 33,177,600 | 33.18 MP | 16× pixels of 1080p; emerging format |
How pixel count scales between resolutions
- • 540p → 720p: 1.78× more pixels
- • 720p → 1080p: 2.25× more pixels
- • 1080p → 4K UHD: 4× more pixels (both dimensions double)
- • 4K UHD → 8K UHD: 4× more pixels
- • 1080p → 8K UHD: 16× more pixels
Uncommon resolutions people ask about (1K, 3K, odd “p” values)
1K video resolution has no official standard — loosely, it means roughly a thousand pixels wide (often 1024×576 at 16:9). 3K is approximately 3072×1728, offered by a few action cameras and drones as a middle ground between 1080p and 4K.
Odd values like 120p, 270p, 380p, 400p, 560p, or 840p are not standard resolutions — they usually come from custom export settings or cropped video. At 16:9, the width is simply the height × 16 ÷ 9 (so 380p ≈ 676×380).
Seeing 1920×1088 instead of 1920×1080? That extra 8-pixel strip comes from video encoders: H.264 works in 16-pixel blocks, so some tools pad 1080 (not divisible by 16) up to 1088 and crop on playback. Your video is still 1080p.
The lowest video resolution on major platforms is 144p (256×144)— YouTube's bottom tier, where text is barely readable.
Which resolution should you use?
YouTube & general upload: 1080p. The best balance of sharpness, file size, and compatibility — and the resolution most viewers actually watch at (see YouTube's recommended resolutions).
TV & living room: 1080p minimum, 4K if the source is high quality. On a 55-inch screen at normal distance, 720p looks visibly soft.
Reels, Shorts & TikTok: 1080×1920 vertical. These platforms compress aggressively, so upload the sharpest master you have.
Slow connections or small embeds: 720p still looks clean on phones and keeps files ~56% smaller than 1080p.
Archiving & masters: always keep the highest resolution you shot (4K if you have it). You can downscale later — you can never upscale detail back. This is exactly what batch converters are for: keep one 4K master, export 1080p, 720p, and vertical copies from it.
Vertical and square video resolutions
Not all video is 16:9 landscape. Reels, Shorts, Stories, and TikTok use vertical (9:16) video, while Instagram feed posts use square (1:1) formats. Here are the common resolutions in those orientations:
| Format | Aspect Ratio | Dimensions | Total Pixels | Used For |
|---|---|---|---|---|
| Vertical 720p | 9:16 | 720 × 1280 | 921,600 | Reels, Shorts, TikTok (HD tier) |
| Vertical 1080p | 9:16 | 1080 × 1920 | 2,073,600 | Reels, Shorts, TikTok (recommended) |
| Vertical 4K | 9:16 | 2160 × 3840 | 8,294,400 | High-quality vertical masters |
| Square 1080 | 1:1 | 1080 × 1080 | 1,166,400 | Instagram feed posts |
The rule is simple: rotate the landscape dimensions 90 degrees. A 16:9 1080p video (1920×1080) becomes a 9:16 vertical video (1080×1920) with the same total pixel count.
What does “p” mean in 720p, 1080p, and 540p?
The “p” stands for progressive scan. In progressive video, each frame displays all lines at once — the entire image appears in a single pass. This produces smooth, flicker-free motion, which is why progressive scan is the standard for all modern digital video.
The number before the “p” is the vertical resolution— the number of horizontal lines stacked from top to bottom. So 540p has 540 lines, 720p has 720 lines, and 1080p has 1,080 lines. That's what the “p” stands for in video quality settings on YouTube and every other platform: the count of progressively-scanned lines.
What does HQ mean in video quality?
HQ simply means High Quality— it's a label YouTube and older players used for the higher-quality stream option (usually 720p or 480p, depending on era and device), as opposed to SQ (Standard Quality). It's not a resolution itself, just a quality tier name.
Progressive vs Interlaced (“p” vs “i”)
You might occasionally see notations like “1080i” (i = interlaced). Interlaced video draws odd lines in one pass and even lines in the next — each frame only contains half the image. This was a bandwidth-saving trick from the CRT television era. All modern content uses progressive scan (p). Interlaced video is effectively obsolete.
What does “K” mean in 4K and 8K?
The “K” stands for thousand and refers to the horizontal resolution (width). 4K is approximately 4,000 pixels wide — specifically 3,840 pixels for consumer 4K UHD and 4,096 pixels for cinema 4K DCI. 8K doubles each dimension again to 7,680 pixels wide.
So the naming logic is: 720p = named by height (720 lines), 4K= named by width (~4,000 pixels). They're measuring different dimensions, which is admittedly confusing at first.
