9:16 in Pixels: 1080×1920 for Reels, TikTok, and Shorts

9:16 Format Dimensions (Straight Answer)

The 9:16 format is the vertical video aspect ratio — the phone screen held upright. The standard pixel dimension is:

1080 × 1920 pixels (width × height).

That means 1080 pixels wide by 1920 pixels tall. This is the resolution expected by Reels, TikTok, and YouTube Shorts, and it’s what Picotta delivers for clips.

9:16 Resolution Table

Any pair of dimensions where height equals width × 16 ÷ 9 is a valid 9:16:

Resolution	Name	When to Use
1080 × 1920	Vertical Full HD	The standard. Works for everything.
720 × 1280	Vertical HD	Smaller file; acceptable but loses sharpness on large screens.
1440 × 2560	Vertical 2K	Higher than what platforms display — they recompress to 1080.
2160 × 3840	Vertical 4K	Same case: platforms downscale. Not worth the file size.

In practice: export at 1080 × 1920 and you’re set. Uploading higher resolution doesn’t improve viewer experience because TikTok, Instagram, and YouTube recompress videos for delivery.

9:16 by Social Platform

• Reels (Instagram): 1080 × 1920. The interface covers the bottom with captions and buttons — leave some margin at the bottom.
• TikTok: 1080 × 1920. Same note about margins: buttons on the right and description below cover part of the video.
• YouTube Shorts: 1080 × 1920, up to 3 minutes long.
• Stories (Instagram/Facebook): also 1080 × 1920.

One size fits all four — which is why 9:16 became the short video format.

How to Convert a Horizontal (16:9) Video to 9:16

Here’s the tricky part. YouTube videos, live streams, or podcasts start in 16:9 (1920 × 1080, landscape). To convert to 9:16, there are only three options:

1. Crop the center — simple, but if the person moves out of the center, they get cut out.
2. Face-tracking crop — the frame follows the speaker. This is what Picotta does with face reframe: AI detects who’s speaking and keeps them framed throughout the clip.
3. Full video with filled background — the full 16:9 video centered, with blurred edges filling the top and bottom. Good for wide shots, screens, and landscapes.

The right choice depends on the scene — and that’s exactly what Picotta decides automatically for each clip: a talking head gets face crop, two people get stacked screens, a slide presentation gets slide + speaker, open scenes get blurred background.
