Are margin percentages based on the source video or the canvas?
Top and bottom percentages use the 1920px canvas height; left and right use its 1080px width. They are not percentages of the source video or the area remaining after black bars. This worked example uses custom margins of 10% top, 20% bottom and 5% on each side, not platform recommendations.
| Setting | Calculation | Result |
|---|---|---|
| Left and right: 5% each | 1080 × 0.05 | 54px each |
| Top 10% / bottom 20% | 1920 × 0.10 / 1920 × 0.20 | 192px / 384px |
| Remaining reference area | 1080 − 54 − 54 / 1920 − 192 − 384 | 972×1344px |
A 1920×1080 landscape video is centered at 1080×607.5px with black space above and below. The guide applies to the whole canvas, not just the video area. A platform that crops your post to fill the screen may show a different composition. This tool does not move subtitles, crop footage or export video; check the posting app before publishing.
Use the cover maker to fill a portrait frame with a photo and add a title.How to use
- Choose a photo or browser-playable video.
- Select a Reels, Shorts or TikTok reference preset and adjust each margin.
- Play or pause to inspect the result and save the current view as PNG.
How it works
The frame is 1080×1920px. Reference width = 1080 × (100 − left% − right%) / 100; height = 1920 × (100 − top% − bottom%) / 100. Defaults are editable ToolTava estimates, not official fixed platform measurements.
Common questions
Is everything in red always obscured?
No. It illustrates possible UI overlap. Organic posts, ads, caption length, controls, devices and app versions differ.
Does it detect or move subtitles?
No. Visually inspect existing subtitles during playback. It does not detect, reposition or re-encode subtitles.
What is downloaded?
A 1080×1920 PNG of the image or current video frame, with the guide if enabled. It does not export video.
How are landscape and transparent files shown?
The entire source fits without stretching, with black space around it. Transparent areas appear over black. Animated images use the initially decoded frame.
What do the official sources cover?
The linked Meta, Google and TikTok sources mainly discuss ad safe zones. They do not establish universal pixel values for organic posts, and this is not an official compliance checker.
