What is the difference between 1080p and 4K?

1080p (Full HD) is 1920×1080 pixels — about 2 megapixels. 4K UHD is 3840×2160 — about 8.3 megapixels, four times as many pixels as 1080p. This means roughly 4× more detail and larger file sizes.

What resolution should I use for YouTube?

YouTube recommends uploading at your source resolution. For most creators, 1080p (1920×1080) is the sweet spot. 4K (3840×2160) is supported and allows YouTube to transcode a sharper 1080p proxy. Minimum recommended is 720p (1280×720).

What is the difference between DCI 4K and UHD 4K?

DCI 4K (used in digital cinema) is 4096×2160 pixels with a 1.9:1 aspect ratio. UHD 4K (used in consumer displays and streaming) is 3840×2160 with a 16:9 aspect ratio. DCI is slightly wider.

What aspect ratio does Instagram Reels use?

Instagram Reels uses a 9:16 vertical aspect ratio at 1080×1920 pixels. This fills the full phone screen. If you upload a 16:9 horizontal video, Instagram will add black bars or crop it.

How do I calculate megapixels from resolution?

Multiply width by height, then divide by 1,000,000. For example, 3840×2160 = 8,294,400 pixels ÷ 1,000,000 = 8.29 MP. The pixel count column in this table does this calculation for you.
