Гид по размерам видео для YouTube: разрешения, соотношения сторон и лучшие практики

In the competitive landscape of digital content, visual quality is the first thing an audience notices. Whether a viewer is tuning in from a massive 4K Smart TV or scrolling through a smartphone on their commute, how your content fits their screen determines if they stay or click away. Uploading a video with the wrong YouTube video size often leads to distracting black bars, blurry resolution, or essential visual information being cut off by the platform's interface.

Mastering the technical side of your uploads isn't just about aesthetics; it’s a vital part of your SEO strategy. In 2026, YouTube’s algorithm increasingly prioritizes high-fidelity content that provides a seamless viewing experience across all devices. This guide will walk you through the essential dimensions, YouTube video size ratio, and file requirements you need to know to ensure your channel looks professional and your videos perform at their absolute best.

What is the ideal size for a YouTube video?

The ideal YouTube video size depends on resolution and aspect ratio. YouTube supports a wide range of formats, but the most recommended setup is:

Resolution: 1920 × 1080 pixels (Full HD);

Aspect ratio: 16:9;

Size limit: 256 GB maximum (or 12 hours irrespective of size);

Best format choice: MOV, MP4, AVI, WMV.

This combination ensures your video looks sharp across all devices without unnecessary file size increases.

Recommended YouTube video dimensions and resolutions

YouTube supports a wide range of resolutions, but not all deliver the best results. Here's the current 2026 standard for 16:9 videos:

For most creators, exporting at 1920 × 1080 (1080p) or higher (such as 4K) provides excellent quality while keeping upload and processing times reasonable. This is widely considered the ideal size of all YouTube videos for balanced performance.

YouTube Shorts dimensions

Viral YouTube Shorts have become a powerhouse for channel growth. A study from 2024 found that while Shorts generate fewer comments than long-form videos, they see significantly more views overall and higher likes per view, making them an essential part of any creator's strategy.

Shorts are designed specifically for mobile-first, vertical viewing. The specs are essentially the inverse of a standard YouTube video:

• Ideal resolution: 1080 × 1920 pixels (ideal); minimum 480p mobile / 720p desktop;
• Aspect ratio: 9:16;
• Maximum length: 60 seconds (Can be upto 3 minutes);
• File format: MP4 (preferred);
• Safe zone: Central 80% of the frame to avoid UI overlaps;

Keep your most important visual elements, faces, text overlays, product shots, anchored to the centre of the frame. The top and bottom edges of the Shorts player are covered by UI elements like the subscribe button, title, and sound controls, so anything placed too close to the edges risks being obscured.

YouTube thumbnail & channel art sizes

Your thumbnail is the single most powerful click-driver on YouTube. Getting the Youtube video dimension size right for thumbnails ensures they look crisp and professional across every surface where it appears — search results, recommended feeds, channel pages, and external shares.

Video thumbnails

In 2026, the minimum YouTube thumbnail size is 640 × 360 pixels, while the recommended size is 1280 × 720 pixels for the best visual quality. This follows a 16:9 aspect ratio, matching standard YouTube video dimensions. Additionally, thumbnail files must not exceed 2MB in size.

Channel banner (channel art)

Your channel banner is one of the trickiest assets to size correctly, because it displays differently across devices — TV, desktop, tablet, and mobile all show different portions of the same image.

In 2026, the minimun banne size is 2048 × 1152 pixels, while the recommended dimension is 2560×1440. Expressed as an aspect ratio, this is 16:9. The maximum YouTube banner file size is 6MB. Supported banner formats are JPG, PNG, Non-animated GIF.

To ensure your design looks perfect across all devices, it’s important to keep essential elements like text and logos within the safe area of 1546 × 423 pixels, centered on the banner. This is because different devices display the banner differently—TVs show the full image, while mobile screens only display the center portion.

Profile picture

YouTube recommends a 800 × 800 pixel profile image with a 1:1 (square) aspect ratio and a max file size of 2 MB. Since it displays as a circle across the platform, avoid placing important elements in the corners.

YouTube video ad specifications

If you are running a marketing campaign, your YouTube video size and length must adhere to strict advertising guidelines. Below are the standard requirements for 2026:

• Skippable in-stream ads: Aspect ratio 16:9, maximum file size 128 GB, video length 12 seconds to 6 minutes.
• Non-skippable in-stream ads: Aspect ratio 16:9, maximum file size 128 GB, video length up to 15 seconds.
• Bumper ads: Aspect ratio 16:9, maximum file size 128 GB, video length up to 6 seconds.
• TrueView ads: Aspect ratio 16:9, maximum file size 128 GB, video length 12 seconds to 3 minutes.
• Video discovery ads: Aspect ratio 16:9, minimum resolution 640 × 360, maximum file size 1 GB.
• Display ads: Aspect ratio 4:3, resolution 300 × 250, maximum file size 150 KB, video length up to 30 seconds.

Best practices for exporting YouTube videos with the right size

Exporting your YouTube videos with the right settings ensures top quality and smooth playback. Follow these best practices to optimize resolution, format, and performance across all devices.

• Use the right resolution: Always export your video in the highest resolution available, ideally 1920 × 1080 (Full HD) or higher, such as 4K (3840 × 2160). Uploading in higher resolution helps preserve visual quality even after YouTube compresses your video, ensuring a sharper and more professional final result.
• Stick to the standard aspect ratio: Using the correct aspect ratio is essential for proper display. A 16:9 aspect ratio is best for standard YouTube videos, while 9:16 is ideal for Shorts. Sticking to these formats prevents black bars and ensures your content looks clean across all devices.
• Choose the recommended format: For the best compatibility and quality, export your videos in MP4 format using the H.264 video codec and AAC audio codec. This combination is optimized for YouTube and provides a perfect balance between file size and video clarity.
• Optimize bitrate settings: Bitrate directly affects your video quality and file size. For 1080p videos, a bitrate of 8–12 Mbps (30fps) or 12–15 Mbps (60fps) is recommended. Choosing the right bitrate ensures your video maintains clarity without creating unnecessarily large files.
• Maintain original frame rate: It’s important to export your video at the same frame rate it was recorded in, whether that’s 24, 30, or 60 frames per second. Changing the frame rate can cause motion issues and reduce the smoothness of your video.
• Use proper audio settings: Clear audio is just as important as video quality. Export your audio using the AAC codec, with a bitrate of 320 kbps and a sample rate of 48 kHz. These settings ensure your sound remains crisp and professional.
• Check file size before uploading: While YouTube supports large file sizes, keeping your video reasonably optimized helps speed up the upload and processing time. Efficient file sizing also ensures a smoother publishing workflow.
• Preview before uploading: Before uploading, always review your video on different devices to catch any potential issues. Check for visual clarity, proper cropping, and audio sync to ensure everything looks and sounds as intended.
