What is the Shorts & Reels Safe Zone Checker?
The Shorts & Reels Safe Zone Checker is a free visual tool that helps YouTube Shorts and Instagram Reels creators avoid one of the most common and costly production mistakes: placing important text, graphics, or on-screen CTAs in areas that the platform’s UI elements will cover. Upload a screenshot or frame from your edited video, and the tool overlays either a realistic Shorts UI mockup or a precise red danger zone map onto your frame, showing exactly which content is at risk of being hidden from viewers.
Both overlay modes serve different purposes. The UI Mockup mode gives you a realistic preview of what viewers will actually see when watching your Short. The Danger Zone mode precisely maps the covered areas in red and highlights the safe center zone in green, making it easy to identify and fix placement issues in your editing software before export.
Why Safe Zones Matter for YouTube Shorts Performance
YouTube Shorts have a complex UI overlay that covers significant portions of the 9:16 frame. The right-side button strip (Like, Dislike, Comment, Share, Save), the bottom gradient panel (Channel name, video description, Subscribe button, hashtags, audio name), and the top navigation bar together cover approximately 35–40% of the total frame area. Any content you place in these zones is invisible to viewers.
This is particularly critical for creators who use text overlays with subscriber CTAs (‘Subscribe for more!’), caption subtitles, watermarks, product display labels, or key information graphics. If these elements land in the danger zones, not only do viewers miss them — the algorithm can’t measure engagement with those elements either, reducing the measurable effectiveness of your CTAs and on-screen information.
- The right-side button strip covers approximately 20% width × 65% height on the right edge
- The bottom panel covers approximately 22% of the frame height from the bottom
- The top navigation gradient covers approximately 10–12% of the frame height from the top
- The combined safe zone is approximately 60% of the total 9:16 frame area
- All captions, text CTAs, and key visuals should be placed in the central safe zone
How to Use the Safe Zone Checker Step by Step
Take a screenshot of your edited Short from your video editing software at the frame where you have your most important text overlay or graphic element. Upload the screenshot using the Upload Frame file input. The tool immediately displays it in a phone-shaped frame mockup. Select ‘Show YouTube UI Mockup’ to see how the real Shorts interface overlaps your content with realistic button and text overlays. This gives you the viewer’s actual perspective.
Switch to ‘Show Red Danger Zones’ to see the precise coverage map. The red zones mark exactly which areas of your frame are covered by UI elements. The green bordered rectangle in the center marks the Safe Zone — the area where your content is guaranteed to be visible on all devices. If your important text falls in the red zones, return to your editing software and reposition those elements toward the center of the frame.
Safe Zone Design Best Practices for Shorts Creators
Once you know where the safe zone is, design all your Shorts with these placement principles from the start to eliminate the need for post-production corrections. The core rule is simple: keep everything important in the central 60% of the vertical frame. But the specific application varies by content type:
- Text overlays and captions: Place in the middle 50% of the frame height, minimum 15% from any edge
- Subscribe or follow CTAs: Center horizontally, place at 30–55% from the top of the frame
- Watermarks and channel logos: Top-left corner at 5–10% from edges (stays outside right-side buttons)
- Face close-ups: Position face in the upper-center of the safe zone for maximum visibility
- Product displays or diagrams: Center the key element; keep labels within the safe zone boundaries
- Subtitle captions: Keep at 55–70% from the top, centered, to avoid the bottom panel overlap
Frequently Asked Questions – Shorts & Reels Safe Zone Checker
The Shorts & Reels Safe Zone Checker is a free tool that lets you upload a screenshot or frame from your edited YouTube Short or Instagram Reel and overlay either a realistic UI mockup (showing where buttons, title text, and subscribe labels appear) or a red danger zone overlay (showing exactly which areas of the frame are covered by platform UI elements). Use it to verify that your important text, faces, and graphics aren’t hidden by platform interface elements.
YouTube Shorts have two primary danger zones: the Right Side Buttons Zone (the vertical strip on the right side of the screen where Like, Dislike, Comment, Share, and Save buttons appear, covering approximately the rightmost 20% of the frame from roughly 15% to 80% of the screen height), and the Bottom Text Zone (the lower 20–25% of the frame where the channel name, video description, and Subscribe button appear, along with hashtags and the audio name). Any important text, graphics, or facial close-ups in these zones will be obscured.
The safe zone for both YouTube Shorts and Instagram Reels is approximately the central 80% width and middle 60% height of the frame — from roughly 15% from the top to 75% from the top, and from 10% to 80% of the width. This safe zone is clearly marked in green in the Danger Zone overlay view. Place all important text, key graphics, calls to action, and close-up faces within this central safe zone to guarantee they’re visible to all viewers on all platforms.
Upload your Short’s screenshot, then select ‘Show YouTube UI Mockup’ using the radio button. This overlays a semi-transparent simulation of the actual YouTube Shorts UI — including the right-side action buttons (Like, Comment, Share, Subscribe button), the bottom gradient with channel name and description text, and the top navigation bar gradient. This view helps you see how the real UI visually interacts with your actual frame content.
Select ‘Show Red Danger Zones’ using the radio button. This overlays bright red semi-transparent rectangles over the exact areas where UI elements appear, making it immediately obvious which portions of your frame are hidden. A green bordered ‘Safe Zone — Place Text Here’ rectangle shows the optimal content placement area. This view is more clinical and precise than the UI mockup view and is the best view for making specific design adjustments.
They are very similar because both platforms use 9:16 vertical video (1080×1920 pixels) with overlaid UI elements in the same general areas. Instagram Reels has its interface buttons on the right side (though slightly different positioning) and text at the bottom. TikTok also follows the same 9:16 format with bottom-left text and right-side buttons. The safe zone recommendation in this tool (center of frame, away from all edges) applies reliably to all three platforms.
Text or graphics in the danger zones will be partially or fully covered by the platform’s UI buttons and overlay elements. Viewers will be unable to read your message, which can cause confusion, lower the effectiveness of on-screen CTAs (like ‘Subscribe’ or ‘Link in bio’ text overlays), and reduce the professional quality impression of your content. For Shorts specifically, the YouTube algorithm also measures engagement with on-screen CTAs — hidden CTAs get zero engagement.
Yes. The tool works with any 9:16 vertical video screenshot regardless of which platform you’re creating for. The safe zone boundaries apply to YouTube Shorts, Instagram Reels, TikTok videos, and any other vertical video format. Upload a screenshot from your video editing software (CapCut, Premiere, DaVinci Resolve) to check your layout before exporting the final video.
In your video editing software, pause the timeline at the frame with your text overlay or key visual element and take a screenshot. In CapCut: pause and tap the three-dot menu > Save Frame. In DaVinci Resolve: right-click on the frame in the viewer > Grab Still. In Premiere Pro: use File > Export > Frame. Export at 1080×1920 resolution for the most accurate safe zone overlay in this tool.
