Reddit Video Length Limit: Complete Guide to Video Specs and Best Practices
Upload fails waste hours. Learn Reddit's exact video specs and best practices to maximize engagement on your first try, every time.

Understanding Reddit's video length limits saves time and prevents frustrating upload errors. Reddit has specific requirements for video content. Getting these right ensures your videos play smoothly and engage viewers effectively.
Videos perform incredibly well on Reddit. They generate higher engagement than text or image posts. But only when you follow the platform's specifications correctly.
Reddit Video Length Limits Explained
Reddit allows videos up to 15 minutes long. This is significantly longer than many other social platforms. The generous limit gives creators plenty of room for detailed content.
However, longer isn't always better. Reddit's audience prefers concise, engaging content. Most successful videos run between 30 seconds and 3 minutes. This length holds attention without testing patience.
File size matters as much as length. Reddit caps video files at 1GB maximum. For most creators, this isn't limiting. But high-resolution, long videos can hit this ceiling quickly.

Technical Video Requirements
Reddit supports MP4 and MOV formats. These are industry-standard video formats that most editing software exports natively. Stick with these formats for guaranteed compatibility.
The maximum resolution is 1080p at 30fps. This provides excellent quality without overwhelming file sizes. Going beyond this resolution is unnecessary and creates upload problems.
H.264/AVC is the required video codec. Most modern video editing and recording software uses this codec by default. If you're experiencing upload issues, check your codec settings.
Quick Video Specs Reference
- Maximum length: 15 minutes
- Maximum file size: 1GB
- Supported formats: MP4, MOV
- Maximum resolution: 1080p (1920x1080)
- Frame rate: 30 FPS maximum
- Required codec: H.264/AVC
- Audio: Supported (no separate audio files)
Optimal Video Aspect Ratios
Reddit supports three main aspect ratios. Each serves different content types. Choosing the right ratio maximizes visual impact and prevents awkward cropping.
16:9 (widescreen) works best for traditional horizontal video. This is the standard YouTube format. Use it for landscape footage, tutorials, and screen recordings.
9:16 (vertical) dominates mobile viewing. Over 60% of Reddit users browse on phones. Vertical video fills mobile screens beautifully and feels native to the experience.
1:1 (square) offers universal compatibility. Square videos work equally well on desktop and mobile. They're perfect for content that needs to work everywhere.

Video Content That Performs Best
Short, engaging videos crush it on Reddit. Front-load your most interesting content. Viewers decide within 3 seconds whether to keep watching.
Silent viewing is standard. Most Redditors scroll with sound off. Add captions or on-screen text to convey your message without audio reliance.
Tutorial and how-to videos generate massive engagement. Redditors love learning new skills. Keep instructions clear, concise, and easy to follow.
High-Performing Video Types
- Quick tips and hacks: 30-60 seconds of actionable advice
- Before and after transformations: Visual proof of results
- Behind-the-scenes content: Authentic glimpses into your process
- Time-lapses: Condensed views of lengthy processes
- Reaction videos: Genuine responses to content or events
GIF Length and Specifications
Reddit treats GIFs differently than standard videos. GIFs have a 1-minute maximum length. Keep them shorter for better loop quality and faster loading.
GIFs can be up to 100MB in file size. But optimal performance comes from files under 10MB. Smaller files load instantly and loop smoothly.
Most successful GIFs run 5-15 seconds. This length captures a complete moment while remaining endlessly watchable. Think quality loops, not mini-movies.

Optimizing Videos for Mobile
Mobile optimization isn't optional. It's essential. Design your videos for vertical viewing first, horizontal second. This flips traditional video thinking but matches user behavior.
Text must be large and legible on small screens. Test on actual phones before posting. What's readable on desktop might be invisible on mobile.
Bright, high-contrast visuals work best. Phone screens vary in quality and brightness. Content that pops regardless of screen conditions wins.
Captions and Subtitles Best Practices
Adding captions multiplies your video's reach. Many users watch without sound in public places or quiet environments. Captions make content accessible to everyone.
Keep caption text concise. Don't overwhelm viewers with walls of text. Break thoughts into bite-sized pieces that appear and disappear naturally.
Use high-contrast caption styling. White text with black outlines works universally. Ensure readability regardless of video background colors.
Caption Creation Tips
- Use automatic caption tools (YouTube, Rev.com) for efficiency
- Review and edit automated captions for accuracy
- Position captions in the lower third of frame
- Time captions to match speech rhythm
- Keep lines short (max 3-4 words per line)

File Compression Strategies
Proper compression maintains quality while meeting size limits. Export videos at moderate bitrates. Excessive bitrates waste space without visible quality improvements.
Use H.264 compression with medium to high-quality settings. This codec balances quality and file size beautifully. Most video editors have presets specifically for online sharing.
Test compression settings with short samples first. Find the sweet spot where quality remains high but file sizes stay manageable. Save these settings as presets for future exports.
Workarounds for Longer Videos
Need to share videos longer than 15 minutes? Post them to YouTube or Vimeo first. Then share the link on Reddit with an engaging preview.
Break long content into series. Post multiple related videos as comments on your original post. This creates sequential viewing while respecting Reddit's limits.
Create highlight reels for Reddit. Post the full version elsewhere. Use Reddit to drive traffic to your long-form content on other platforms.
Thumbnail Selection Matters
Reddit auto-generates thumbnails from your video. But you can upload custom thumbnails. Eye-catching thumbnails dramatically increase click-through rates.
Design thumbnails with bold text and clear subjects. They should communicate value at a glance. Think of thumbnails as mini-billboards for your content.
Test multiple thumbnail options. Different images attract different audiences. A/B testing reveals which thumbnails perform best for your content type.
Video Upload Best Practices
Upload during low-traffic times for faster processing. Reddit's servers handle uploads more quickly when less congested. This prevents timeout errors and failed uploads.
Use wired internet connections when possible. WiFi can introduce instability during large file uploads. Wired connections ensure smooth, uninterrupted transfers.
Double-check videos before uploading. Watch the entire export to catch errors. Fixing issues after uploading wastes time and looks unprofessional.
Pre-Upload Checklist
- Video meets technical specs (format, resolution, length)
- File size under 1GB
- Audio and video sync properly
- Captions or text overlays included
- First 3 seconds hook viewers
- Content appropriate for target subreddit
Common Video Upload Errors
File size exceeded is the most common error. Compress your video more aggressively or reduce resolution. Quality differences are minimal but file size drops significantly.
Format not supported means you're using an unsupported codec. Re-export as MP4 with H.264 codec. This solves most format-related issues.
Upload failed errors often indicate connection problems. Check your internet stability. Try uploading during different times if problems persist.
Engagement-Boosting Video Tactics
Start with a hook that stops scrolling. The first frame should intrigue viewers instantly. Use bold text, striking visuals, or surprising moments.
Keep pacing tight. Remove dead air and unnecessary pauses. Every second should add value or entertainment. Respect your audience's time ruthlessly.
End with a clear call-to-action. Ask for upvotes, comments, or shares. Direct viewer behavior rather than hoping they engage organically.
Accessibility Features
Make videos accessible to all users. Add detailed descriptions in your post text. Describe what happens visually for those using screen readers.
Use clear, well-lit footage. Poor lighting excludes people with visual impairments. High-quality footage benefits everyone, not just those with perfect vision.
Provide transcripts for longer videos. Post them in comments. This helps everyone and improves your content's searchability on Reddit and Google.
Analytics and Improvement
Track which videos perform best. Note their length, style, and topic. Double down on what works rather than guessing blindly.
Pay attention to drop-off points. If viewers consistently leave at specific moments, improve those sections. Tighten pacing or add more engaging content.
Read comments for feedback. Viewers often tell you exactly what they want. Listen and adjust your content strategy accordingly.
