What are YouTube Shorts?

YouTube Shorts are vertical, short-form videos (under 60 seconds) designed to be consumed quickly and easily on mobile devices. They’re YouTube’s answer to TikTok and Instagram Reels, designed to capture viewers’ attention through snappy, engaging content.

Since their introduction, Shorts have become a viral phenomenon. They are favored by the YouTube algorithm, often appearing on the Shorts shelf and recommended to millions of viewers daily. Shorts offer incredible opportunities for:

Rapid channel growth

Massive views, even for small creators

Affiliate marketing and product promotion

CPM monetization through ads

Content automation (especially when created with tools like aicut.pro)

But to leverage these benefits, you need to pay attention to one of the most common pitfalls: incorrect video size and formatting.

Why Video Size Matters for YouTube Shorts

If your Shorts have the wrong size, aspect ratio, or format, YouTube’s algorithm may not classify them correctly or feature them on the Shorts shelf. That means losing out on potentially millions of organic views.

Proper video size ensures:

Maximum discoverability on mobile devices

Optimal playback quality (no black bars or awkward cropping)

Higher user engagement

Eligibility for Shorts-featured placement

Proper monetization tracking

Let’s break down the precise specs you need for maximum success.

Official YouTube Shorts Video Size & Specs (2024)

YouTube outlines specific requirements for videos to be classified as “Shorts.” Here’s what you need to know:

1. Aspect Ratio

The ideal aspect ratio is 9:16 (vertical).

This matches most smartphone screens, ensuring a full, immersive experience.

2. Video Dimensions

Recommended size: 1080 pixels (width) x 1920 pixels (height)

These dimensions maintain high resolution and clarity on all devices.

3. Video Length

Maximum length: 60 seconds (anything longer won’t be classified as a Short)

There’s no strict minimum, but most Shorts perform best between 15-30 seconds.

4. File Types

Supported formats: MP4 (most recommended), MOV.

5. File Size

Maximum recommended file size is around 2GB, but uploading smaller files ensures faster processing.

| Spec | Requirement |

|--------------------|-------------------------------------|

| Aspect Ratio | 9:16 |

| Dimensions | 1080 x 1920 px |

| Length | Up to 60 seconds |

| File Type | MP4 (preferred), MOV |

| File Size | Up to 2GB (recommended) |

Remember: If your video doesn’t conform to these, it could end up as a regular YouTube video, not a Short.

Best Video Length for YouTube Shorts

While up to 60 seconds is allowed, research shows that videos between 15 and 30 seconds generally have the highest completion rates and the best chance of going viral. Here's why:

Shorter videos grab attention instantly and minimize drop-off rates.

More frequent posting is possible, boosting your channel’s algorithmic momentum.

Greater replay-ability, leading to higher total watch time.

Pro Tip: Experiment with various lengths, but try to focus your core message or call-to-action within the first 5-10 seconds to hook viewers.

---

Recommended Aspect Ratio and Resolution

Let’s clarify why the 9:16 aspect ratio and 1080 x 1920 pixels are crucial for YouTube Shorts video size.

9:16 aspect ratio: This is taller than it is wide (vertical), matching how people naturally hold smartphones.

1080 x 1920 pixels: This is Full HD in a vertical format, providing crisp, clean visuals without pixelation.

#### Common Mistakes to Avoid

Uploading horizontal videos (16:9): They may display with black borders and won’t fill the screen—viewers dislike this!

Using non-standard resolutions: Such as 720 x 1280. While technically allowed, higher resolution looks more professional and future-proofs your content.

Incorrect aspect ratios (like 1:1 or 4:5): These don’t qualify as official Shorts.

Always check your export settings before uploading.

---

File Type, Size Limit, and Other Tech Specs

Here’s the tech breakdown for YouTube Shorts video uploads:

Preferred file type: MP4 (best combination of quality and size)

Video codec: H.264

Audio codec: AAC

Frame rate: 24, 30, or 60 fps supported—higher frame rates offer smoother motion

File size: While YouTube allows up to 256GB, keep Shorts under 2GB to avoid upload delays

Tip: Compress your videos if needed, but don’t sacrifice visual quality—blurry or pixelated videos are less likely to perform well.

6. Optimize Descriptions and Hashtags

Use keyword-rich descriptions (like “youtube shorts video size”) and relevant hashtags (#Shorts, #YouTubeShorts, #ViralShorts) to improve discoverability.
