Shorts resolution on YouTube: 1080p maximum, and what it means for 4K
By the KeyMo team · Updated
YouTube Help says you can upload Short videos with a maximum resolution of 1080p. It lists no minimum resolution for Shorts. A 4K master is therefore above the stated limit, and the pages do not say what happens to it. For a vertical Short, 1080x1920 is the practical top size.
What YouTube states, as of 11 October 2026
| Item | What YouTube says | Help article |
|---|---|---|
| Shorts maximum resolution | Upload Short videos at a maximum of 1080p | Get started creating YouTube Shorts; Create YouTube Shorts |
| 1080p (HD) in pixels | 1920x1080, in a table for the default 16:9 ratio | Video resolution & aspect ratios |
| Regular videos | Resolutions are listed from 240p up to 8K (4320p) | Video resolution & aspect ratios |
| 5K and similar | YouTube started removing playback of resolutions between 4K and 8K in 2022 | Video resolution & aspect ratios |
| Container and codec | MP4, H.264 video, AAC-LC or Opus audio at 48 kHz | Recommended upload encoding settings |
| Colour space | BT.709 for SDR uploads | Recommended upload encoding settings |
What YouTube does not state
- A minimum resolution for Shorts. The pages we read give none.
- A pixel size for vertical video. The table lists 16:9 sizes only, so 1080x1920 is our rotation of 1920x1080, not a printed figure.
- What happens to a Short uploaded above 1080p. The page says 1080p is the maximum and stops there.
- A maximum bitrate. YouTube says no bitrate limit is required and gives recommended bitrates for reference.
Can a Short be 4K?
YouTube's help says the maximum resolution for a Short upload is 1080p. That settles the common question about 4K Shorts: the stated ceiling is 1080p, so a 4K file gains nothing the pages promise. The same article shows 4K and 8K are valid for regular videos, which is where the confusion comes from. Exporting a vertical clip above 1080x1920 adds file size and upload time without a stated benefit.
Settings YouTube recommends for a 1080p upload
These are general upload recommendations, not rules written for Shorts. They are a useful checklist before you hit publish.
| Setting | YouTube's recommendation |
|---|---|
| Video bitrate, 1080p SDR, up to 30 fps | 8 Mbps |
| Video bitrate, 1080p SDR, 48 to 60 fps | 12 Mbps |
| Frame rate | Upload at the rate it was recorded; 24, 25, 30, 48, 50 and 60 are named as common |
| Audio bitrate | 128 kbps mono, 384 kbps stereo |
| Container | MP4, no edit lists, moov atom at the front |
What KeyMo exports
Every KeyMo clip is vertical 9:16 at 1080x1920, 30 fps, H.264/AAC, so it matches the 1080p limit exactly and uses the H.264 and AAC pairing YouTube recommends. KeyMo does not export 4K. If your source is a YouTube link, import fetches video only up to 1080p, so a 4K upload is fetched at 1080p or lower. Clips carry no watermark on any plan.
Sharpness depends on the source more than the export size. A soft, dim or heavily compressed 1080p episode will look softer once it is cropped to vertical. See the aspect ratio page for the crop arithmetic and the file size calculator to estimate an upload.
