The multi-platform dimension problem

Every social platform has preferred video dimensions. Instagram feed wants 4:5. Stories and Reels want 9:16. YouTube wants 16:9. LinkedIn accepts multiple formats but performs best at specific sizes. Twitter has its own preferences.

Posting the wrong dimensions means your video either gets letterboxed (black bars), cropped automatically by the platform (often cutting off important content), or displayed at suboptimal size.

Getting dimensions right is one of the simplest ways to look more professional on every platform.

Platform dimension reference

Instagram

Feed post (square): 1080x1080 (1:1). Still works but takes less screen space than 4:5.

Feed post (portrait): 1080x1350 (4:5). Takes maximum feed space. Recommended for most feed content.

Reels/Stories: 1080x1920 (9:16). Full vertical. Required for Reels and Stories.

Landscape: 1080x608 (16:9). Acceptable but takes minimal screen space. Avoid for engagement-focused content.

TikTok

Standard: 1080x1920 (9:16). Vertical is the only option that looks native.

YouTube

Standard video: 1920x1080 (16:9). The default and expected format.

Shorts: 1080x1920 (9:16). YouTube's vertical format.

4K: 3840x2160 (16:9). For creators with 4K content and audience with 4K screens.

Feed: 1920x1080 (16:9) or 1080x1080 (1:1). Both work well. Horizontal tends to perform slightly better.

Vertical: 1080x1920 (9:16). LinkedIn now supports vertical video in the feed.

Twitter/X

Standard: 1920x1080 (16:9) or 1280x720.

Vertical: 1080x1920 (9:16) supported but 16:9 remains most common.

Using the canvas editor

The canvas editor lets you place your video on any size canvas with full control over positioning, sizing, and background.

1. Open the canvas tool

2. Upload your video

3. Select target dimensions

Choose from presets (1:1 Square, 4:5 Instagram, 9:16 Vertical, 16:9 Landscape) or enter custom dimensions.

4. Position your video

Drag, scale, and position your video within the canvas. You can:

Fill the canvas (crop to fit)
Fit within canvas (letterbox with background)
Custom position and scale

5. Set background

When your video does not fill the canvas, choose what goes behind it:

Solid color (black, white, brand color)
Gradient
Blur of the video itself (popular for vertical videos on horizontal canvases)
Rounded corners for a modern look

6. Export

Download at your chosen dimensions, ready for upload.

Rounded corners and modern touches

A growing trend on social media is videos with rounded corners on colored backgrounds. This look feels more polished and designed than edge-to-edge video.

The canvas editor supports rounded corners natively. Set your canvas color, add rounded edges to your video, and the result looks like a premium, designed piece of content.

Strategy: one source, multiple outputs

The efficient approach:

Film and edit at the highest resolution available (ideally 4K 16:9)
Export your master file
Use canvas editor for platform-specific sizing
Use auto reframe for intelligent vertical crops
Add captions sized for each platform's viewing context
Apply consistent color grading across all versions

One editing session produces content for every platform.

Common mistakes

Relying on platform auto-crop. Platforms crop your video to fit their preferred dimensions. The crop is usually centered, which may cut off important elements at the edges.

Using the same file everywhere. A horizontal YouTube video posted to TikTok without reformatting looks lazy and performs poorly.

Ignoring safe zones. Platform UI elements (buttons, usernames, descriptions) overlap certain areas of the frame. Keep critical content away from edges, especially on TikTok and Instagram.

Wrong resolution. Uploading 720p to a platform that supports 1080p looks noticeably softer. Always match or exceed the platform's recommended resolution.

Inconsistent dimensions across posts. Your grid or profile looks cleaner when all videos use the same dimensions for a given platform.

Safe zones by platform

TikTok: Keep text and important elements away from the top 150px (username area) and bottom 250px (caption/music area).

Instagram Reels: Similar to TikTok. Avoid bottom 200px and top 100px for critical content.

YouTube Shorts: Keep content centered vertically. Bottom 100px is covered by title and description.

All platforms: Always preview your video in the app before publishing to verify nothing gets hidden.

Quick workflow

For most creators, the fastest workflow is:

Canvas editor to set dimensions and background
Film filters for color treatment
Auto captions for text overlay
Export and upload

Total time per platform version: 5-10 minutes.
