YouTube Video Resolutions
YouTube supports a wide range of resolutions, all at 16:9 aspect ratio:
| Label | Resolution | Recommended Bitrate (SDR) |
|---|---|---|
| 240p | 426 × 240 | 0.7 Mbps |
| 360p | 640 × 360 | 1 Mbps |
| 480p | 854 × 480 | 2.5 Mbps |
| 720p HD | 1280 × 720 | 5 Mbps |
| 1080p Full HD | 1920 × 1080 | 8 Mbps |
| 1440p (2K) | 2560 × 1440 | 16 Mbps |
| 2160p (4K) | 3840 × 2160 | 35-45 Mbps |
| 4320p (8K) | 7680 × 4320 | 80-160 Mbps |
Always upload at native resolution — never upscale. Higher bitrates preserve detail through YouTube's re-encoding pipeline.
HDR & High Frame Rate
For HDR or 60 fps content, double the recommended SDR bitrates above. YouTube uses different encoders for HDR (PQ or HLG) and high frame rate, both of which need more data to look clean.
Container & Codec
- Container: MP4 (recommended) or MOV
- Video codec: H.264 (universal) or HEVC/AV1 (better for 4K+)
- Audio codec: AAC-LC, 48 kHz, 384 kbps stereo (or 5.1 surround)
- Color profile: Rec. 709 for SDR, Rec. 2020 PQ for HDR
- GOP length: half the frame rate (e.g. 15 frames at 30 fps)
- B-frames: 2 between reference frames
- Closed GOP: yes
- Variable bitrate: yes (1-pass or 2-pass)
Frame Rate Guide
- 24 fps: cinematic look — narrative, vlogs, talking-head
- 30 fps: standard — most YouTube content
- 60 fps: smooth motion — gaming, sports, fast cuts
- 120 fps: not natively supported — use 60 fps
Don't mix frame rates within one upload. Pick one and stick to it across the timeline.
Aspect Ratio Behavior
- 16:9 (1920 × 1080): Native — fills the player
- 4:3 (1440 × 1080): Pillarboxed (black bars on sides)
- 1:1 (1080 × 1080): Pillarboxed
- 21:9 (cinema scope): Letterboxed (black bars top/bottom)
- 9:16 (1080 × 1920): Pillarboxed in regular feed; use the Shorts format instead
Tips for Better YouTube Video Performance
- Upload at native resolution — never upscale
- Use H.264 at recommended bitrate (or HEVC/AV1 for 4K+)
- Add captions or upload an SRT — boosts watch time and SEO
- Use 60 fps for fast motion, 24-30 fps for everything else
- Always upload in sRGB / Rec. 709 unless mastering for HDR
- Need to convert formats? Use a dedicated encoder before upload to skip YouTube\'s queue.
Frequently Asked Questions
What is the YouTube video size?
The recommended YouTube video size is 1920 × 1080 pixels (1080p Full HD) at a 16:9 aspect ratio. YouTube also supports 720p, 1440p, 4K, and 8K — all at 16:9 — with proportionally higher bitrates.
What is the YouTube video aspect ratio?
The standard YouTube video aspect ratio is 16:9 (widescreen). Other ratios get pillarboxed (4:3, 1:1, 9:16) or letterboxed (21:9 ultrawide). For Shorts, use 9:16 vertical instead — they get a separate distribution shelf.
What is the maximum file size for a YouTube video?
The maximum file size is 256 GB or 12 hours of length, whichever comes first. Most uploads stay well under both limits — a 30-minute 1080p video typically runs 1.5-3 GB.
What is the recommended bitrate for YouTube?
YouTube recommends 8 Mbps for 1080p SDR, 16 Mbps for 1440p, 35-45 Mbps for 4K, and 80-160 Mbps for 8K. Double these for HDR or 60 fps. Higher bitrates preserve detail through YouTube's re-encoding.
What format should I upload to YouTube?
Upload MP4 or MOV containers with H.264 video codec and AAC-LC audio at 48 kHz. HEVC and AV1 are supported and recommended for 4K+ to keep file size manageable. AVI, WMV, FLV, and 3GP also work but add encoding time.
What frame rate should I use for YouTube?
Use the frame rate you shot in: 24 fps for cinematic, 30 fps for standard, 60 fps for gaming or fast motion. YouTube accepts 24, 25, 30, 48, 50, and 60 fps. Avoid mixed frame rates within one upload — pick one and stick to it.
How long can a YouTube video be?
YouTube allows up to 12 hours per video and 256 GB max file size for verified accounts. Unverified accounts are capped at 15 minutes. Verify by adding a phone number to your account.
Should I upload at 4K if my content is shot in 1080p?
No. Upscaling 1080p to 4K just adds file size and upload time without quality benefit. Upload at native resolution. However, a 1080p video uploaded inside a 4K container can sometimes get YouTube's higher-bitrate 4K encoder, which preserves slightly more detail — this is a known trick but yields marginal returns.
