Every platform has different aspect ratios, character limits, and UI overlay areas. Here's your complete reference for creating content that looks perfect everywhere.
Aspect Ratio

Max Chars
2,200
Safe Zone
Avoid right 15% (like/comment/share buttons) and bottom 33% (caption area, music bar, username).
Tip: Keep key visuals in the center-left area. Text overlays should be in the top 50% to avoid caption overlap.
Aspect Ratio
4:5
Resolution
1080 x 1350
Visible Chars
125 visible
Max Chars

Safe Zone
Bottom 12% is covered by action buttons (like, comment, share, save).
Tip: The first 125 characters appear before "...more". Front-load your most important text for maximum engagement.
Aspect Ratio

Safe Zone
Top 10% (username bar, progress indicators) and bottom 25% (reply bar, sticker tray).

Top 10% (Reels label), right 12% (like/comment/share buttons), bottom 25% (caption, audio, username).
Tip: The most visible area is center-left. Your reel cover image is cropped to 4:5 in the grid, so keep key visuals centered.

Bottom 12% (action buttons). Carousel dot indicators appear at the bottom center.

Max Chars

Safe Zone
Bottom 15% (title overlay, source attribution, save button).
Tip: Pinterest favors vertical 2:3 pins. Use bold text overlays on the image itself — the title field is very short.

From solo creators to enterprise marketing teams — anyone who posts to social media benefits from previewing content before publishing.
Preview client content across every platform before posting. Ensure images and captions look perfect everywhere — no surprises after publishing.
Check that your thumbnail, reel cover, or carousel image isn't obscured by platform buttons, captions, or music bars before posting.
Teach social media best practices with real-time previews. Show students exactly how content renders differently on each platform.
Validate creative designs against real platform constraints. Ensure logos, text, and key visual elements stay within safe zones.
Standardize content review workflows. Preview and approve social posts across all platforms before they go live.
Plan multi-platform campaigns with confidence. See how one piece of content adapts across TikTok, Instagram, LinkedIn, and more.
Common questions about previewing posts, danger zones, aspect ratios, caption truncation, and platform-specific formatting.
Yes, 100% free with no usage limits and no signup required. We built it as a companion to our scheduling tool, SocialCal. We also offer a free Fake Tweet Generator and LinkedIn Carousel Maker.
No. Images are processed entirely in your browser using the FileReader API. Nothing is sent to our servers. Your content stays on your device at all times.
Danger zones are areas where platform UI elements (buttons, music bars, captions, avatars) overlap your image content. Our red overlays show you exactly where these are so you can position key visual elements — logos, text, faces — in safe areas. This is especially important for TikTok, Instagram Reels, YouTube Shorts, and Stories.
We support 13 formats across 8 platforms: TikTok Video, Instagram Feed, Story, Reel, and Carousel, YouTube Shorts, X/Twitter, LinkedIn, Threads, Pinterest, Facebook Feed, Story, and Reel. Each preview uses the correct aspect ratio and UI layout.
Currently the tool supports image previews. For video content, your uploaded image serves as a thumbnail or cover frame preview, showing how your content will be framed and where danger zones overlap.
Our previews closely match real platform dimensions, UI layouts, and character truncation rules. Aspect ratios, caption character limits, and UI element positions are all based on current platform specifications as of 2025.
For best results, upload at least 1080px wide. Use 1080x1920 for stories/reels (9:16), 1080x1350 for feed posts (4:5), 1000x1500 for Pinterest (2:3), and 1200x675 for Twitter (16:9). Our previewer works with any image size.
Yes! The tool is fully responsive. On mobile, the controls collapse to the top and previews display in a single column. We also show fewer platforms by default on mobile for a cleaner experience.
There is no single "best" ratio because platforms differ significantly. However, 4:5 (1080x1350) works well for Instagram Feed, Facebook Feed, Threads, and carousels. For Stories, Reels, TikTok, and Shorts, you need 9:16 (1080x1920). That's exactly why this previewer exists — to check each format.
Each platform shows a different number of characters before hiding the rest behind a "See more" or "...more" button. For example, Instagram shows ~125 characters, LinkedIn shows ~140, and Twitter shows the full 280. Our previewer simulates this exactly so you can optimize your opening text.
