Video Size Guide for TikTok, Instagram, YouTube & More — Exact Dimensions

Every Platform's Video Dimensions — Quick Reference

Each social platform wants a specific aspect ratio and resolution. Upload the wrong size and your video gets cropped awkwardly, letterboxed with black bars, or compressed to blurry mush. Here is what each platform actually wants:

Platform	Format	Aspect Ratio	Resolution	Max Length
TikTok	Feed / For You	9:16	1080×1920	10 min
Instagram Reels	Reels	9:16	1080×1920	90 sec
Instagram	Feed (square)	1:1	1080×1080	60 sec
Instagram	Feed (portrait)	4:5	1080×1350	60 sec
Instagram	Story	9:16	1080×1920	15 sec/slide
YouTube Shorts	Shorts	9:16	1080×1920	60 sec
YouTube	Standard	16:9	1920×1080 (or 4K)	12 hrs
LinkedIn	Feed video	1:1 or 16:9	1080×1080 or 1920×1080	10 min
Twitter/X	Feed video	16:9 or 1:1	1920×1080 or 1080×1080	2 min 20 sec
Facebook	Feed	16:9, 1:1, or 4:5	1080p	240 min
Facebook	Reels	9:16	1080×1920	90 sec

The pattern: Vertical short-form content (TikTok, Reels, Shorts) = 9:16 at 1080×1920. Standard YouTube = 16:9 at 1920×1080. Everything else is 1:1 or flexible.

How to Resize for Any Platform in 60 Seconds

1. Open the Video Resizer
2. Drop your video — any format (MP4, MOV, MKV, etc.)
3. Select the target platform or enter custom dimensions
4. Choose how to handle mismatched aspect ratios (crop, fit, or stretch)
5. Download the resized video

Example: You recorded a 16:9 landscape video (1920×1080) and need it for TikTok (9:16). The resizer crops the center of the frame to 1080×1920 — you get the middle portion of your video in the correct vertical format.

If cropping cuts off important parts, use the Video Cropper to manually position the crop area before resizing.

TikTok — The Most Searched Platform

TikTok is the #1 reason people search for video resizing tools. The specifics:

• Required: 9:16 vertical, 1080×1920 pixels
• File size: Under 287MB (iOS) or 72MB (Android) for uploads
• Format: MP4 or MOV
• What happens if wrong: TikTok auto-crops landscape videos to fill the vertical frame — usually cutting off the left and right sides. You lose context and it looks unprofessional.

The smart workflow:

1. Crop your landscape video to 9:16 — position the crop area on the most important part of the frame
2. Resize to 1080×1920 if it is not already at that resolution
3. Compress if the file is over 72MB (common for 4K source videos)

This gives you full control over what viewers see, instead of letting TikTok's auto-crop make bad choices.

One Video → Every Platform

Shot one video and need it everywhere? Here is the efficient workflow:

1. Start with the highest resolution source — ideally 4K or 1080p landscape (16:9)
2. YouTube standard: Use as-is at 16:9, or resize to 1920×1080 if it is 4K and you want smaller files
3. TikTok / Reels / Shorts: Crop to 9:16 → resize to 1080×1920
4. Instagram feed: Crop to 4:5 → resize to 1080×1350 (takes up the most feed space)
5. LinkedIn / Twitter: Keep at 16:9 or crop to 1:1 for square format
6. Add subtitles to the vertical versions — 85% of social video is watched on mute. Use the Subtitle tool to burn captions in.

You end up with 3-4 versions of the same video optimized for each platform. Total time: about 5 minutes per version.

Common Mistakes That Kill Video Quality

• Upscaling low-res video — resizing a 480p video to 1080p does not add detail. It just makes the blur bigger. Always start with the highest resolution source.
• Stretching instead of cropping — stretching a 16:9 video to 9:16 makes everything look tall and distorted. Always crop, never stretch (unless you want a deliberately warped aesthetic).
• Compressing before resizing — compress AFTER resizing. If you compress first, then resize, you lose quality twice. Resize first, then compress the final version once.
• Ignoring safe zones — TikTok and Instagram overlay UI elements (username, caption, buttons) on the bottom 15-20% of the screen. Keep important content in the center 60% of the frame.
