The correct instagram reels cover size is 1080×1920 pixels at a 9:16 aspect ratio. That's the easy part. The hard part is that Instagram displays Reels covers at two completely different crops on the same platform — full 9:16 inside the Reels player and the dedicated Reels tab, and a 4:5 center crop in your main profile grid. A cover that looks perfect inside the player can lose its headline the moment it appears on your profile, and most creators don't notice until engagement drops.
This guide covers the exact cover size, how Instagram crops covers in each context, where the safe zones sit, the most common cover problems, and the best practices that keep Reels covers sharp and clickable across every Instagram surface.
The correct instagram reels cover size is 1080×1920 pixels at a 9:16 aspect ratio. This matches the full-screen vertical Reels format and is the same canvas Instagram uses for Stories, plus the same format as TikTok and YouTube Shorts. Reels covers are vertical-first — there's no other supported size.
| Spec | Value | Notes |
|---|---|---|
| Width | 1080 px | Below 1080 = visibly soft after compression |
| Height | 1920 px | Below 1920 = upscaling artifacts |
| Aspect ratio | 9:16 | The only supported Reels cover ratio |
| File format | JPEG, PNG | JPEG for photos, PNG for graphics with text |
| Grid crop | 1080×1350 (4:5) | Center-cropped from your 9:16 upload |
Always upload at the full 1080×1920 resolution (or higher, downsampled cleanly). Lower resolutions get visibly soft after Instagram's compression. Verify your image dimensions with the Instagram Post Size Checker before uploading.
Reels covers face the dual-display problem that defines vertical content on Instagram. Your 9:16 cover lives in two completely different contexts on the same platform, and they crop very differently.
When someone taps your Reel, the cover plays at its full 9:16 size. No cropping at this stage. Instagram overlays interface elements on top of your image:
The dedicated Reels tab on your profile shows covers at the full 9:16 ratio with no center-cropping — same view as the player. A small Reels icon overlays the top-right and a view count sits in the bottom-left of each tile.
This is where most cover designs fail. On the main profile grid (the regular Posts tab), Reels covers display at a 4:5 ratio (1080×1350) instead of the full 9:16. Instagram achieves this by center-cropping the top and bottom of your 9:16 image:
A headline placed in the top 285 px or a logo in the bottom 285 px is fully visible in the Reels player but completely invisible on your profile. This is the single most common reason Reels covers look fine when you upload but get cropped on your profile. The fix is to design for the 4:5 grid crop first — if it works at 4:5, it will also work full-screen.

Because your cover appears at two different crops, you need to design for two overlapping safe zones. Important content should always stay centered — avoid the top and bottom edges entirely, and design for both contexts simultaneously.
The area that's safe in both views is approximately Y:285 to Y:1560 on a 1080×1920 canvas — about 1275 px of vertical space in the center, with the rightmost 80 px reserved for the full-screen UI. Place all headlines, faces, logos, and key visuals inside this overlap zone. Important content should always stay centered. Design for the grid first, then verify the full-screen view second.
For the full safe-zone reference across every Instagram placement, see the Instagram Safe Zones Guide. For Story-specific safe zones, see the Instagram Story Safe Zone tool.
Headlines placed in the top or bottom 285 px of a 9:16 cover are visible in the Reels player but completely hidden in the main profile grid 4:5 crop. Move all text into the vertical center of the canvas, between Y:285 and Y:1635.
A face positioned near the top or bottom edge gets sliced by the 4:5 grid crop. Center faces vertically — the face should sit in the middle third of the canvas, not near any edge. Verify the result with the Instagram Reels Cover Preview.
Instagram compresses every uploaded image. Starting at the full 1080×1920 resolution (and ideally 1440×2560 downsampled to 1080×1920) helps your cover survive compression with sharp detail. Verify dimensions with the Instagram Post Size Checker before uploading.
The grid view is small — about 120 px wide on a typical phone. Covers with multiple competing elements, busy backgrounds, or small text become illegible at that size. One focal point. One short headline. That's it.
Light text on a light background or dark text on a dark background disappears at thumbnail size. Use high-contrast color pairs (white text with a dark stroke or shadow, bright text on a dark photo). Fix contrast issues in the Free Thumbnail Editor with built-in text effects, shadows, and outlines.
If you don't manually pick a custom cover, Instagram auto-selects a frame from your Reel — often mid-blink, mid-motion, or with no clear focal point. Always tap "Cover" when publishing and either pick a stronger video frame or upload a custom 1080×1920 image designed for the 4:5 grid crop.
