YouTube rejects or downgrades media that don’t meet its requirements. A 4:3 video gets pillarboxed with black bars, while a vertical clip longer than 3 minutes is published as a normal video instead of a Short. Also, a thumbnail larger than 2 MB can fail upload requirements. For an agency managing multiple client channels, one incorrect export can result in a failed post for a client brand.
This page lists the exact YouTube media sizes for videos, Shorts, thumbnails, and channel art. It covers the file size and duration limits that can block an upload. It also explains how RecurPost flags a spec issue before the post publishes.
YouTube Video Size and Format Specs
A standard YouTube video uses a 16:9 aspect ratio with a resolution of 1920 × 1080 or higher. For video uploads, YouTube recommends MP4 as the container, H.264 as the video codec, and AAC-LC audio at 48 kHz. It also recommends uploading videos at their original frame rate and supports 24, 25, 30, 48, 50, and 60 fps.
Moreover, YouTube supports resolutions from 720p to 8K, while 1080p remains the standard choice for most client uploads. For 16:9 videos, the recommended minimum resolution is 1280 × 720. YouTube also recommends bitrate settings based on resolution and frame rate. For example, YouTube recommends 8 Mbps for 1080p videos at 30 fps, and 12 Mbps for 1080p videos at 60 fps.
| Attribute | Specification |
|---|---|
| Container | MP4 (recommended). Also accepts MOV, AVI, WMV, FLV, MPEG-4, WebM. |
| Video codec | H.264, High Profile, progressive scan. |
| Audio codec | AAC-LC at 48 kHz. |
| Aspect ratio | 16:9 standard. Other ratios get pillarboxed by the player. |
| Resolution | 1280 x 720 minimum for 16:9. 1920 x 1080 standard. Up to 3840 x 2160 (4K) and 7680 x 4320 (8K). |
| Frame rate | 24, 25, 30, 48, 50, or 60 fps. Deinterlace before upload. |
| Recommended bitrate (1080p) | 8 Mbps at 30 fps, 12 Mbps at 60 fps. |
| Maximum file size | 256 GB. |
| Maximum length | 12 hours. |
In a typical agency use case, an agency editor can export a single 1080p MP4 master and publish it across multiple client channels without a re-export. However, avoid uploading interlaced 1080i footage. YouTube deinterlaces interlaced video during processing, which often produces a softer result than a true 1080p30 export.
YouTube Shorts Size and Specs
A YouTube Short uses a 9:16 vertical aspect ratio at 1080 × 1920 and can run for up to three minutes. In October 2024, YouTube increased the maximum Shorts length from 60 seconds to 3 minutes. Furthermore, YouTube tags a video as a Short when it uses a vertical or square format and remains within the three-minute limit.
| Attribute | Specification |
|---|---|
| Aspect ratio | 9:16 vertical (square 1:1 also eligible). |
| Resolution | 1080 x 1920. |
| Maximum length | 3 minutes. |
| Frame rate | 24 to 60 fps. |
| Format | MP4, H.264, AAC (same as standard upload). |
For instance, a freelancer repurposing a client’s Reel into a YouTube Short can use the original 9:16 master from the original edit. However, a 16:9 horizontal version of the same clip publishes as a normal video rather than a Short.
YouTube Thumbnail Size
A YouTube thumbnail should be 1280 × 720 pixels with a 16:9 aspect ratio and remain under 2 MB. YouTube accepts JPG, PNG, GIF, and BMP file formats. In addition, custom thumbnails require a verified channel, so make sure to confirm the client account is verified before you set one.
| Attribute | Specification |
|---|---|
| Recommended size | 1280 x 720. |
| Minimum width | 640 px. |
| Aspect ratio | 16:9. |
| Maximum file size | 2 MB. |
| Formats | JPG, PNG, GIF, BMP. |
| Requirement | Verified channel for custom thumbnails. |
For example, an agency designer can crop a 16:9 thumbnail to 1280 × 720 inside RecurPost. In addition, RecurPost’s image editor applies a platform preset to keep the thumbnail within YouTube’s specifications. As a result, the thumbnail attaches to the scheduled video without requiring a separate design tool.
YouTube Channel Banner and Profile Picture Sizes
A YouTube banner appears across TV, desktop, and mobile devices. Therefore, it should use a resolution of 2560 × 1440 and keep key text within the 1235 × 338 safe area. In addition, YouTube limits banner files to 6 MB.
A YouTube profile picture should use a resolution of 800 × 800 pixels with a 1:1 aspect ratio. However, YouTube displays the image as a circle and typically renders it at approximately 98 × 98 pixels.
| Asset | Specification |
|---|---|
| Banner recommended size | 2560 x 1440. |
| Banner minimum size | 2048 x 1152. |
| Banner safe area | 1235 x 338, centered. |
| Banner maximum file size | 6 MB. |
| Profile picture size | 800 x 800 (1:1). |
| Profile picture formats | JPG, PNG, non-animated GIF, BMP. |
An ideal use case scenario, being an agency managing channel art across multiple locations, can build a single banner template around the 1235 × 338 safe area. As a result, each location channel can reuse the template without losing logo visibility on mobile devices.
YouTube File Size and Length Limits
YouTube accepts uploads up to 256 GB or 12 hours in length, whichever limit is reached first. While these file size and duration limits rarely affect agencies, the 15-minute upload limit on new channels can create issues. YouTube restricts unverified channels to uploads of up to 15 minutes until the channel is verified with a phone number.
For example, an agency onboarding a new client channel may encounter this limit during its first long-form upload. Therefore, verify the channel before scheduling videos longer than 15 minutes.
Why YouTube Uploads Fail on Spec and How to Catch Them Early
Most failed YouTube uploads result from a specification mismatch, such as an unsupported codec, an oversized thumbnail, an incorrect aspect ratio, or an expired channel token. However, RecurPost maps more than 850 platform error types. As a result, YouTube publishing failures appear with a clear reason instead of remaining silent in the publishing queue.
In addition, RecurPost lets you configure the YouTube settings that affect publishing at scheduled times. You can set the privacy status (public, private, or unlisted), category, title, and tags before the video publishes. RecurPost’s built-in image editor also crops thumbnails to the 16:9 1280 × 720 spec by using a platform preset.
RecurPost fits agencies that need to identify specification issues before content reaches a client channel. However, it may be less important for an individual creator who manually publishes one video each week. For example, an agency managing 20 client channels can identify an incorrect thumbnail aspect ratio in the preview, correct it in the editor, and reschedule the post before publication.
How to Schedule YouTube Media in RecurPost
RecurPost publishes YouTube media that meets platform specifications through a single workflow. First, connect the client channel through a password-free invite. Then, schedule YouTube videos from the same dashboard you use to manage other social media platforms.
Follow these steps to upload, review, and schedule YouTube media in RecurPost.
- Connect the channel: The client authorizes their YouTube account through an email or link invite, so no password sharing is required.
- Upload the video or Short: Then, crop the thumbnail to 1280 × 720 using the built-in image editor.
- Configure YouTube settings: Set the title, category, tags, and privacy status before publishing.
- Preview the post: Confirm that the video format and thumbnail meet YouTube specifications.
- Schedule the upload: Publish immediately, add the video to a queue, or bulk-schedule multiple client videos at once.
Different social media platforms support different video sizes and image specifications. Therefore, RecurPost provides a social media video size guide and a social media image size reference for every supported platform.
