The numbers in a list like "360p · 720p · 1080p · 2160p" describe how many lines of pixels a video has from top to bottom. More lines means more detail — and a bigger file. Choosing well saves storage, mobile data and time.
What the numbers mean
- 360p / 480p (SD) — standard definition. Fine on a small phone screen, soft on anything bigger.
- 720p (HD) — sharp on phones and small laptops. The sweet spot for saving data.
- 1080p (Full HD) — sharp on laptops, monitors and most TVs. The best default for keeping a video.
- 1440p (2K) and 2160p (4K) — for large TVs, big monitors and editing. Much bigger files.
Vertical videos (Reels, TikToks) are described the same way by their shorter side, so a 1080×1920 vertical video is "1080p".
How much space does each take?
File size depends on how the platform compressed the video, but these are realistic averages for one minute of typical social media video:
- 360p: about 3–6 MB per minute
- 720p: about 8–15 MB per minute
- 1080p: about 15–30 MB per minute
- 4K: about 60–150 MB per minute
So a 30-second 1080p Reel is roughly 10 MB, while a 10-minute 4K video can be over a gigabyte. Zovan shows the size of each option when it's known, so you can decide before downloading.
Which quality for which screen
- Watching on your phone: 720p looks nearly identical to 1080p on most phones and is about half the size.
- Laptop or tablet: 1080p.
- TV or big monitor: 1080p, or 4K if the original is 4K and your TV supports it.
- Editing for your own content: always the highest available — you can make it smaller later, never bigger.
- On mobile data: 480p or 720p, especially for long videos.
"Best / Original" — what it means
Choosing Best / Original asks for the highest quality the platform has for that video. It can never be better than what the creator uploaded: a video recorded in 720p won't become 1080p, and platforms compress everything they store. If a creator uploaded in 4K and the platform kept it, Best / Original gets you 4K.
Frame rate: the other number
Sometimes you'll see "60" after the resolution (1080p60). That's frames per second. 60 fps makes fast motion — gaming, sports — look smoother, but makes the file bigger. For talking, cooking and most social content, 30 fps is all you need.
Why does my downloaded video look worse than in the app?
Usually because a lower resolution was chosen, or because the original upload was low quality. Apps also sharpen and upscale on screen. Download the highest option available and compare on the same device.
