Best Bitrate for 1080p, 1440p, and 4K Video

Two major platforms publish recommended upload bitrates, and they do not agree. This guide sets their tables side by side for 1080p, 1440p and 4K, and shows what each figure costs in storage for a ten-minute clip.

The short answer

There is no single best bitrate, and any site that gives you one has invented it. What exists is published guidance from the platforms you deliver to, and it differs between them.

For standard dynamic range at 24, 25 or 30 fps, YouTube recommends 8 Mbps for 1080p, 16 Mbps for 1440p and 35–45 Mbps for 2160p. Vimeo recommends 10–20 Mbps for 1080p, 20–30 Mbps for 2K and 30–60 Mbps for 4K. Pick from the platform you are uploading to, then use the Video Bitrate Calculator if you need to fit that inside a size budget instead.

What each platform publishes

YouTube’s recommended upload encoding settings give a single figure or a narrow range per resolution, split by frame rate. For SDR uploads:

Resolution 24, 25, 30 fps 48, 50, 60 fps
2160p (4K) 35–45 Mbps 53–68 Mbps
1440p (2K) 16 Mbps 24 Mbps
1080p 8 Mbps 12 Mbps
720p 5 Mbps 7.5 Mbps

The same page publishes a separate and higher set for HDR uploads — 10 Mbps for 1080p, 20 Mbps for 1440p and 44–56 Mbps for 2160p at the standard frame rates — and recommends the MP4 container with the H.264 video codec.

Vimeo’s compression guidelines are structured as ranges without a frame-rate split:

Resolution Recommended
8K 50–80 Mbps
4K 30–60 Mbps
2K 20–30 Mbps
1080p 10–20 Mbps
720p 5–10 Mbps
SD 2–5 Mbps

Vimeo also advises keeping the source frame rate and choosing a constant rather than a variable frame rate.

Both tables are advice about what each platform’s transcoder prefers to receive. Both change over time. Every figure above was read from the publisher’s own page on 2026-08-11, and the links are in the Sources section so you can check them against the current version.

The resolutions these numbers attach to

YouTube’s resolution page lists the pixel dimensions the bitrate table assumes for 16:9 material: 1080p is 1920x1080, 1440p is 2560x1440, and 2160p is 3840x2160.

Those dimensions are worth holding on to, because they show why the recommended bitrates do not scale with pixel count. 2160p has four times the pixels of 1080p — 8,294,400 against 2,073,600 — yet YouTube’s recommendation rises from 8 Mbps to 35 Mbps, a factor of 4.4, and Vimeo’s midpoints rise from 15 Mbps to 45 Mbps, a factor of 3. Compression does not work per-pixel, and neither table pretends it does.

Worked example: what each bitrate costs in storage

Take a ten-minute clip with a 384 Kbps stereo track and run YouTube’s three SDR standard-frame-rate figures through the file size formula:

fileSizeBytes = (videoBitrate + audioBitrate) x durationSeconds / 8
1080p  (8 000 000 + 384 000) x 600 / 8 =   628 800 000 bytes = 628.80 MB
1440p (16 000 000 + 384 000) x 600 / 8 = 1 228 800 000 bytes =   1.23 GB
2160p (35 000 000 + 384 000) x 600 / 8 = 2 653 800 000 bytes =   2.65 GB

Going from 1080p to 2160p multiplies the file by 4.22, not by 4, because the audio track is a fixed addition that does not scale. Every one of those lines reproduces in the Video File Size Calculator.

Choosing when you have a size limit instead

Sometimes the constraint is not a platform recommendation but a hard ceiling: a file that has to fit a specific size. Then the bitrate is an output, not an input.

For a 1 GB budget over ten minutes with a 128 Kbps audio track:

payloadBits  = 1 000 000 000 x 8   = 8 000 000 000 bits
totalBitrate = 8 000 000 000 / 600 = 13 333 333.333... bps
videoBitrate = 13 333 333.333... - 128 000 = 13.205 Mbps

13.205 Mbps sits inside Vimeo’s 1080p range and above YouTube’s 1080p recommendation, so this budget is comfortable at 1080p and short of both platforms’ 1440p guidance. That is the kind of judgement the arithmetic supports. The Video Bitrate Calculator produces the same figure.

The same method answers the reverse planning question. If the budget is a card or a drive rather than a single file, divide the capacity by the runtime you need and work from there. A 30-minute delivery inside 1 GB gives a total of about 4.44 Mbps, which falls below both platforms’ 1080p guidance — a signal that either the size limit or the target resolution has to move, rather than a number to quietly accept.

Where a size limit and a resolution recommendation are genuinely incompatible, the useful output is the gap itself. Reporting “this budget supports 4.4 Mbps and the platform recommends 8” is a decision someone can act on; silently encoding at 4.4 and hoping is not.

Rate control changes what “a bitrate” means

A recommended bitrate assumes you are asking the encoder for a bitrate at all. Many encoders do not default to that.

The x265 documentation states that CRF “is the default rate control method; it does not try to reach any particular bitrate target, instead it tries to achieve a given uniform quality and the size of the bitstream is determined by the complexity of the source video.” An encode left on its default therefore produces whatever bitrate the footage demands, which may be well above or below a platform recommendation.

If you want to hit a published number, you have to select a bitrate-targeting mode explicitly. CBR vs VBR covers the modes and when each is appropriate.

What this does not tell you

  • These are recommendations, not requirements. Neither platform states that an upload outside its range is rejected. Both re-encode what they receive.
  • No number here is a measurement. Nothing on this page was tested, benchmarked or compared visually. Every figure is either quoted from a publisher’s page or computed from the formula shown.
  • The tables change. They carry an access date for that reason. A figure that has not been re-checked in six months is flagged in this project’s content inventory rather than left to age silently.
  • Codec is not accounted for. The recommendations are written for the codec each platform recommends. See H.264 vs H.265.

Frequently asked questions

Why do YouTube and Vimeo recommend different bitrates for 1080p?

Because they are describing what their own transcoders prefer to receive, not a property of 1080p. YouTube publishes 8 Mbps; Vimeo publishes 10–20 Mbps. Neither is wrong. Use the one for the platform you are delivering to.

Both platforms re-encode uploads, so a much higher bitrate mostly costs you upload time. The upload time calculator will show what that costs on your connection before you commit to it.

Does a higher frame rate need a higher bitrate?

YouTube’s table says so explicitly: 1080p rises from 8 Mbps at 24–30 fps to 12 Mbps at 48–60 fps, and 2160p from 35–45 to 53–68 Mbps. Vimeo’s table does not split by frame rate at all.

What about HDR?

YouTube publishes a separate HDR table with higher figures: 10 Mbps for 1080p, 20 Mbps for 1440p and 44–56 Mbps for 2160p at standard frame rates. Vimeo’s guidelines as published do not give a separate HDR bitrate table.

Is there a best bitrate for 1440p specifically?

YouTube recommends 16 Mbps at standard frame rates and 24 Mbps at high frame rates. Vimeo’s nearest entry is 2K at 20–30 Mbps. The gap between those is real and this site does not split the difference for you.
