Instagram Reels are short-form vertical videos designed to entertain, educate, or inspire, often in 15 to 60 seconds. Since launching in 2020, Reels have taken center stage in Instagram’s algorithm, driving over 2 billion plays per day and becoming one of the most engaging content formats for creators and brands alike. However, a key detail that’s often overlooked is the correct Instagram Reel size.
You could spend hours creating a video, only to see it awkwardly cropped in the feed or ignored because it doesn’t display properly on viewers’ screens. That’s a missed opportunity for reach, engagement, and building brand trust.
That’s why, in this article, we’ll show you the exact Instagram Reel size dimensions, break down safe zones, cover sizes, aspect ratios, and technical specs, so your content looks as good as it performs.

Why Getting Instagram Reel Size Right Matters
Reels are designed to be full-screen and immersive, but only if your video matches Instagram’s format. You might think posting is as easy as tapping “share,” but Instagram Reel size really matters. Using the wrong dimensions can hurt both appearance and performance.
- Maximizing screen real estate for full-screen impact
- Preventing visual cutoffs and awkward cropping
- Boosting reach with better algorithmic performance
- Creating a polished, professional brand appearance
- Increasing engagement by guiding viewers’ focus effectively
What’s more, for businesses, visual quality reflects your brand identity. Posting poorly sized Reels can make your brand appear careless or unprofessional, damaging credibility and conversion rates.
So, ready to make your Reels stand out the right way? Let’s move on to the exact specs you need.
Instagram Reel Size
Before we dive into the details of Instagram Reel size, take a moment to check out this handy cheat sheet. It’s a quick, go-to guide you can save and refer back to anytime you’re creating Reels, so that you can get the dimensions just right for a polished, professional look.
Details | Recommended size / limit | Details |
Feed size in pixels | 1080 x 1920 pixels | Full vertical frame (9:16 aspect ratio) |
Aspect ratio | 9:16 (full-screen) | Ideal for immersive mobile viewing |
Feed crop aspect ratio | 4:5 | Reels in feed view are cropped; stay within this for important visuals |
Thumbnail size | 1080 x 1080 pixels | Square crop shown on profile grid |
Cover size | 1080 x 1920 pixels | Same as video size; center design to fit all views |
Safe zone | 1080 x 1350 pixels (4:5) | Keep key text and visuals within this area to avoid UI overlay |
File format | MP4 or MOV | MP4 with H.264 codec recommended |
Maximum file size | 4GB | Stay under this for smooth uploads |
Instagram Reel frame rate | 30 or 60 FPS | For smooth motion and better visual quality |
Reel length | Up to 3 minutes | Best engagement often between 15 - 60 seconds |
Caption length | 2,200 characters | Only first 125 characters appear before cut-off |
Instagram Reel size in pixel
The ideal Instagram Reel size is 1080 x 1920 pixels with a 9:16 aspect ratio. For best results, upload videos in MP4 or MOV format. This vertical video dimension fits Instagram’s full-screen layout and ensures your Reel appears sharp, centered, and visually optimized.
You might be tempted to upload in 4K thinking it will improve quality, but Instagram automatically downscales everything to 1080p. That means you won’t see a quality boost, and your upload may even take longer or get compressed in ways you can’t control.
On the flip side, uploading in a lower resolution (like 720p) may result in blurry or pixelated videos, especially when stretched to fit the vertical format.
Sticking to 1080 x 1920 pixels in Instagram Reels size width and height not only ensures your Reel looks crisp, but also keeps your file size manageable and Instagram-friendly. It’s the smart choice for creators who want the best visual quality without technical headaches.
Pro tip: If you’re editing outside Instagram (like in Premiere Pro, Final Cut Pro, or CapCut), always set your sequence or canvas to 1080 x 1920 with a vertical orientation. This ensures that when you export your final file, it’s already optimized for upload without needing resizing or cropping.
Instagram Reel video ratio
The standard Instagram Reel aspect ratio is 9:16. This is the ratio Instagram Reels are optimized for and how they appear when viewed in full-screen mode.
However, when a Reel shows up in a viewer’s Instagram feed (not in full-screen), it gets cropped to a 4:5 ratio. This cropping reduces the visible area of your video and can potentially cut off key visuals or text elements near the top or bottom of the frame.
Most users don’t always tap into full-screen mode while scrolling. If your Reel only looks good in 9:16, you risk losing important content when it’s auto-cropped to 4:5 in the feed.
To avoid this, make sure your key visuals and on-screen text stay within the 4:5 safe zone. It keeps your content engaging and viewable no matter how your audience consumes it.
Instagram Reel frame size
The exact Instagram Reel frame size is 1080 pixels wide by 1920 pixels tall, following a 9:16 aspect ratio.
This frame size defines the total visible area of your video, essentially, what your audience will see on screen whether they’re watching in full-screen mode or scrolling through their feed
However, not every part of this frame is always fully visible. Instagram overlays key interface elements, like usernames, captions, buttons, and interaction icons, on top of your video, especially along the top and bottom.
To design effectively, it’s best to keep all essential content, like text, product highlights, or calls-to-action, within the central 1080 x 1350 pixel area, which corresponds to a 4:5 aspect ratio.
Instagram Reel cover size
The recommended Instagram Reel cover size is 1080 x 1920 pixels, matching the full vertical frame of the video itself.
Your Instagram Reel cover is the thumbnail image that represents your video on your profile grid, in the Reels tab, and sometimes even on the Explore page. It’s the first thing people see before deciding whether to tap and watch, so getting the cover size right is key to grabbing attention and maintaining a consistent brand aesthetic.
Instagram thumbnail Reel size
The exact Instagram thumbnail Reel size is 1080 x 1080 pixels.
The Instagram Reel thumbnail is the cropped image that appears in your profile grid when you choose to display a Reel there. While your original Reel video is 1080 x 1920 pixels, Instagram automatically crops the thumbnail to a square format: 1080 x 1080 pixels.
If you want more control over how your Reel appears in your feed, Instagram allows you to upload or select a specific frame as a custom cover. Always preview the square crop before posting to ensure your visuals look clean and intentional.
Instagram Reel length
Instagram Reels can be up to 3 minutes long, but that doesn’t mean you should always use the full duration. While Instagram technically allows longer videos, shorter Reels between 15 to 60 seconds tend to perform better in terms of engagement, especially for mobile users with short attention spans.
If you’re aiming for virality or reach, keep your content concise, punchy, and value-packed within the first few seconds. Instagram’s algorithm favors videos that are watched in full and rewatched, so a well-edited 30-second Reel may get more traction than a 3-minute one.
Instagram Reel caption length
The maximum Instagram Reel caption length is 2,200 characters, which gives you room for storytelling, hashtags, and calls-to-action. However, keep in mind that only the first 125 characters show up before the “More” cut-off, especially on mobile.
This means your hook, CTA, or key message should always appear right at the top to catch attention. After that, you can dive deeper, include hashtags, tag collaborators, or add context.
While long captions can add value, avoid fluff. Focus on clarity, relevance, and structure. Break up long text with line spacing or emojis to improve readability.
Instagram Reel Safe Zones
When designing Reels, it’s not enough to just fit your Instagram Reel size into the 1080 x 1920 pixel frame. You also need to consider safe zones, areas within the video that are guaranteed to remain visible, regardless of where your Reel appears or how it’s overlaid with Instagram’s interface elements.
Instagram places buttons, captions, usernames, and icons on top of your video, especially near the top 250 pixels and bottom 450 pixels. If your important text or visuals fall into those areas, they can easily get blocked or cut off, making your content look cluttered or hard to understand.
To avoid this, keep all critical elements like titles, product shots, CTAs, and faces within the central 1080 x 1350 pixel space, which roughly matches a 4:5 ratio. This safe zone ensures your content looks great whether it’s seen in the full-screen Reel player, in the feed, or on the Explore page.

Instagram Reel Compression
Instagram applies automatic compression to all uploaded Reels, which can affect the visual quality of your video.
Maximum file size
The maximum file size for an Instagram Reel is 4GB. Staying under this limit ensures your video uploads smoothly without quality loss or error prompts. If your video is longer or shot in high bitrate, compress it slightly before upload using a trusted video editor.
Video format & codec
Instagram supports MP4 and MOV formats, but MP4 (H.264 codec) is the most widely recommended. It delivers high-quality visuals at a reasonable file size, making it ideal for social platforms. Using MP4 also helps prevent unexpected format errors during upload.
Resolution compression & quality tips
While you can film in 4K, Instagram will automatically downscale everything to 1080 x 1920 pixels. Uploading higher resolutions won’t improve quality and may result in unnecessary compression artifacts. On the other hand, videos below 1080p can appear pixelated or blurry after Instagram’s processing. The best practice is to export your video at 1080 x 1920 pixels at 30 or 60 FPS for optimal clarity.
To minimize compression artifacts:
- Avoid overly detailed backgrounds or high-noise scenes
- Use clean cuts and moderate motion
- Maintain consistent lighting for smoother encoding
Upload settings
For the best results, turn on the “Upload at highest quality” setting in your Instagram app:
- Go to Settings & activity
- Scroll down to Your app and media section,then tap Media quality
- Toggle on “Upload at highest quality”
This tells Instagram to preserve your video’s clarity during upload, even if it takes a bit longer or uses more data. It’s a small setting that makes a big difference, especially for creators who care about visual impact.

Common Instagram Reel Dimensions Mistakes to Avoid
Even seasoned creators slip up when it comes to sizing their Reels correctly. But if you want your content to look polished, perform well, and display correctly across all of Instagram’s views, it’s important to avoid these common mistakes.
- Placing text or key visuals too close to the edge: Important content near the top or bottom 250 pixels can get blocked by Instagram’s UI (captions, buttons, usernames).
- Using low-resolution videos (below 1080 x 1920 pixels): Videos with low resolution may appear blurry or pixelated after Instagram’s compression and upscaling.
- Neglecting cover and thumbnail cropping: Failing to center key elements can lead to awkward cropping in the profile grid (which uses a square 1:1 display).
- Skipping high-quality upload settings: Not enabling “High-Quality Uploads” in Instagram settings can cause excessive compression and lower visual clarity.
