You export a Reel that looks sharp on your phone, upload it, and Instagram hands back a softer, slightly cropped version with the hook text hiding under the caption and a cover that shows on your profile as a random slice of someone's forehead. Nothing was wrong with the video. The specs were wrong — and Instagram has changed several of them in the last eighteen months: the length cap, the profile grid, what counts as recommendable, and where the on-screen buttons sit.
Instagram Reels are 9:16 vertical video at 1080 x 1920 pixels. A Reel can be up to 3 minutes long (raised from 90 seconds in January 2025), and Instagram says it only recommends Reels of 3 minutes or less to people who don't follow you, so 15 to 60 seconds remains the sweet spot for reach. Export MP4 or MOV with H.264 video and AAC audio at 30 fps, keep essential text out of roughly the top 14 percent and bottom 35 percent of the frame, and design the 1080 x 1920 cover with the subject centered, because the profile grid crops it to a portrait rectangle.
This guide covers the exact specs, what happens to non-9:16 uploads, length rules, export settings, safe zones, the cover crop, audio, how Reels compare with Stories, feed video, TikTok, and Shorts, and how to produce correctly sized Reels at volume — by hand, with free tools, or with an automated engine like Vidpal that renders every video at 1080 x 1920 with captions inside the safe zone.
What size is an Instagram Reel in 2026?
The correct Instagram Reel size is 1080 pixels wide by 1920 pixels tall, a 9:16 aspect ratio, exported as an MP4 or MOV with H.264 video and AAC audio. The full specification follows, one item per paragraph; Instagram's own summary is on its Reel size and aspect ratios help page, which is where to check if anything moves.
Dimensions: 1080 x 1920 pixels. Instagram serves video at up to 1080 pixels wide, so a larger export is downscaled on upload. Meta's Reels ad spec lists 1440 x 2560, so uploading at 2x is not wrong; it just does not display any larger.
Aspect ratio: 9:16. Reels accept a wide range of ratios, but the Instagram Platform documentation states that Meta recommends 9:16 “to avoid cropping or blank space.”
File type and codecs: MP4 or MOV container, H.264 (or HEVC) video, AAC audio. The Reel specifications Meta publishes for the Instagram API call for progressive scan, closed GOP, 4:2:0 chroma subsampling, and the moov atom at the front of the file.
Frame rate: 30 fps is the standard. Meta's API spec accepts 23 to 60 fps. Match your source footage rather than converting.
Bitrate: Meta's API spec caps video at 25 Mbps variable bitrate and lists 128 kbps for AAC audio at up to 48 kHz. In practice a Reel exported around 8 to 12 Mbps looks identical after Instagram recompresses it.
Length: up to 3 minutes in the app, with a 3-second minimum. Meta's API spec permits uploads up to 15 minutes; the length section below covers the longer-limit reports and why 3 minutes is the number that matters.
File size: the Instagram API spec lists a 300 MB maximum. The app is widely reported to accept files up to about 1 GB, though Instagram does not publish that number. A 60-second Reel at 10 Mbps is roughly 75 MB, so size is rarely the constraint.
Cover image: 1080 x 1920 pixels, either a frame from the video or a separate upload, cropped to a portrait rectangle on your profile — so the subject and any title need to sit in the center.
Caption: up to 2,200 characters, with only the first line or two visible before the “more” link. Instagram cut the hashtag cap sharply in a late-2025 change, so treat three to five specific tags as the target and check the current limit on the help center.
What aspect ratio do Reels use, and what happens to 16:9, 4:5, and 1:1 uploads?
Reels use a 9:16 vertical aspect ratio, and every other ratio is padded with blank space or cropped depending on where Instagram displays it. Instagram does not reject a horizontal or square video; it just shows it badly.
A 16:9 landscape upload (1920 x 1080) sits in the middle of the frame with large blank bands above and below, and the caption and audio label overlap the bottom of the picture. Reframe it: crop to 9:16 around the subject, or stack the clip over a blurred, zoomed copy of itself so the frame is full. The free crop video tool does the first in a browser.
A 4:5 portrait upload (1080 x 1350) is the friendliest non-9:16 option: thin bands in the Reels tab, a perfect match for the feed's display ratio, and almost nothing lost in the grid. Acceptable for repurposed feed video, though it reads as a repost.
A 1:1 square upload (1080 x 1080) leaves roughly a quarter of the frame blank above and below and gives the caption overlay nothing to sit on but empty space. Square is the ratio to convert, not tolerate. For how each ratio behaves on every platform, see our guide to video aspect ratios.
How long can an Instagram Reel be in 2026?
An Instagram Reel can be up to 3 minutes long. Instagram raised the cap from 90 seconds in January 2025, a figure its help center still lists. The more important number is on Instagram's creator FAQ, which states that Instagram recommends videos to unconnected audiences — people who do not follow you — only when they are 3 minutes or less. A Reel over 3 minutes is not a reach play; it is content for followers.
Meta's API spec allows uploads up to 15 minutes, and industry coverage through late 2025 described a 20-minute recording option reaching a limited set of creator and business accounts. Instagram has not documented that on its public help pages as of this writing, so treat it as a rollout you may or may not have. Either way, nothing over 3 minutes is shown to non-followers.
Within the cap, length should follow the goal. For pure reach — hooks, reactions, a single fact — 7 to 15 seconds keeps completion rates high enough to be replayed. For how-to and educational Reels, 30 to 60 seconds is the range most creators find holds attention while delivering a complete idea. Storytelling and talking-head content can run 60 to 90 seconds if the first three seconds earn it. Our guide to the ideal video length for every platform breaks these ranges down by format.
Trial reels let you test length without risking your feed. Meta introduced trial reels in December 2024: toggle a Reel as a trial and it is shown to non-followers first, stays off your grid and Reels tab, and reports views, likes, comments, and shares after about 24 hours. You can also let Instagram share it with followers automatically if it performs well on views in the first 72 hours. If you are unsure whether a 30-second or a 2-minute cut will land, run both as trials.
What resolution, bitrate, and export settings should you use for Reels?
Export Reels at 1080 x 1920, 30 fps (or 60 if the source is 60), H.264 High profile in an MP4 container, variable bitrate around 8 to 12 Mbps, with AAC audio at 48 kHz and 128 to 256 kbps. Those settings sit inside every published limit and give Instagram's recompression a clean source.
From a phone, the setting that matters is inside Instagram: under data usage and media quality, turn on upload at highest quality so Instagram does not send a reduced version on a slow connection. Film at 1080p or 4K in the native camera app and import the file rather than recording inside the Instagram camera. Meta's own Edits app, launched in April 2025, exports at full quality straight to Reels.
From CapCut, choose 1080p, 30 or 60 fps, and the higher bitrate option. From Premiere Pro, use H.264, a 1080 x 1920 frame, VBR 2-pass with a target around 10 Mbps and a maximum around 16, and maximum render quality. If you are starting from a 4K or ProRes master, run it through the free video compressor first — our guide on how to compress a video explains the trade-offs.
Where are the safe zones for text and captions on a Reel?
Keep essential text, faces, and logos out of the top 14 percent, the bottom 35 percent, and 6 percent on each side of a 1080 x 1920 Reel. On that canvas the margins are about 269 pixels at the top, 672 pixels at the bottom, and 65 pixels on each side, leaving a usable area of roughly 950 x 979 pixels in the middle. Those percentages come from Meta's own Reels ad specs, which tell advertisers to keep those areas free of text and logos so the interface does not cover them.
The bottom zone is large because everything Instagram overlays stacks there: username and follow button, caption, hashtags, audio attribution, and for ads a call-to-action button. The right edge holds the like, comment, share, and save column. Organic Reels carry slightly less than ads, so the ad safe zone is the conservative one. Meta publishes a downloadable template on its help page about text overlays and the safe zone — drop it into your editor as a guide layer once and every project inherits it.
For burned-in captions, the practical placement is just below the vertical midpoint, roughly 1,100 to 1,250 pixels from the top, centered and no wider than about 900 pixels. That keeps two lines well above the bottom zone even when the caption overlay expands. The same video is also shown cropped to 4:5 in the home feed, where the top and bottom 285 pixels are gone, so anything that must be seen everywhere belongs in the central 1080 x 1350 band.
What size is a Reel cover, and how does the profile grid crop it?
A Reel cover is 1080 x 1920 pixels, the same 9:16 size as the video, but it is almost never displayed at that size. On your profile it appears as a portrait thumbnail that crops the top and bottom; in the home feed it shows at 4:5; and in a few older placements it can still appear square. Design it as a 9:16 image whose subject and title sit inside the central 1080 x 1350 area and it works everywhere.
The grid changed in January 2025, when Instagram replaced square thumbnails with tall rectangles because, as Adam Mosseri said at the time, most of what people upload is vertical. Most guides put the tile at 3:4, which fits Instagram adding native support for uncropped 3:4 photos in May 2025, though Instagram's help center does not state the figure; either way a 9:16 cover loses roughly the top and bottom quarter, somewhere between 240 and 285 pixels from each end. Instagram's cover editor shows a profile grid preview; use it and drag the crop until the subject reads as a thumbnail.
Keep title text between roughly 400 and 1,500 pixels from the top, and keep covers consistent in style so the grid reads as a series — the same discipline that makes carousel cover slides work, as our guide to Instagram carousel size and dimensions explains.
How should captions, on-screen text, and fonts be sized for Reels?
Caption text on a Reel should be at least 60 to 70 pixels tall on a 1080-pixel-wide canvas, set in a bold sans-serif with a solid or outlined background, and limited to two lines of five or six words. Most viewers watch on a phone at arm's length, often with sound off, and smaller text becomes unreadable once Instagram compresses the video.
Instagram's auto-captions are generated after upload, sit inside the safe zone automatically, and can be toggled off by the viewer; burned-in captions are what most high-performing Reels use because they can be styled, animated word by word, and positioned deliberately. The free auto caption generator produces burned-in captions, and our complete guide to AI subtitles and captions for Instagram Reels covers timing and accuracy. Font choice is legibility, not decoration: heavy geometric sans-serifs hold up under compression and white text with a dark stroke beats any color scheme on a busy background. Our roundup of the best fonts for subtitles lists the ones that survive a 9:16 render.
What audio can you use in a Reel?
Reels can use original audio, music from Instagram's audio library, or the original audio of another public Reel. Which library you see depends on account type: personal and creator accounts get the full licensed catalog of popular music, while business accounts generally see a royalty-free library, because commercial use of popular music is licensed differently. Instagram's help page on access to the licensed music library explains which account types get what.
Technically, keep audio as stereo AAC at 48 kHz and 128 to 256 kbps. Trending sounds can help discovery, but a Reel built on a licensed track can be muted if posted from a business account or cross-posted where the license does not apply. Our walkthrough on how to add music to Instagram covers the mechanics, and our guide to copyright rules for short-form video in 2026 covers what happens when you get it wrong.
Reels vs Stories vs feed video: how do the specs compare?
All three Instagram video formats share the same 1080 x 1920, 9:16 canvas, but they differ in length, display ratio, and how long they stay visible.
Reels: 1080 x 1920 at 9:16, up to 3 minutes, permanent on your profile, and eligible for recommendation to non-followers at 3 minutes or under. Full-screen in the Reels tab, cropped to 4:5 in the home feed, cover cropped to a portrait rectangle on the profile.
Stories: 1080 x 1920 at 9:16, each segment playing up to 60 seconds with longer uploads split automatically into 60-second cards. Stories disappear after 24 hours unless saved to Highlights and have their own overlays at the top and bottom, so the safe zone is roughly the top and bottom 250 pixels. Our guide to how long an Instagram Story can be covers the splitting rules.
Feed video: any video posted to the feed is published as a Reel, so the same 9:16 and 3-minute rules apply. The difference is display: the feed shows video at 4:5, so a 9:16 file loses the top and bottom 285 pixels there, while a 1080 x 1350 file shows in full in the feed but with bands in the Reels tab.
Reels vs TikTok vs YouTube Shorts: are the specs the same?
The canvas is the same — 1080 x 1920 at 9:16 on all three — but length caps, safe zones, and cover behavior differ, so one export serves all three only if you design to the strictest safe zone and stay under the shortest cap.
Instagram Reels: 1080 x 1920, up to 3 minutes, recommended to non-followers only at 3 minutes or under, safe zone of roughly 14 percent top and 35 percent bottom, cover cropped to a portrait rectangle.
TikTok: 1080 x 1920, up to 10 minutes for in-app uploads and longer for some accounts, with a bottom overlay of caption and sound plus the right-hand button column covering a similar area to Reels. Our TikTok video size and dimensions guide has the full spec.
YouTube Shorts: 1080 x 1920, up to 3 minutes since October 2024, with the title, channel name, and subscribe button along the bottom and the button column on the right. Shorts get a separate thumbnail rather than a cropped cover. Our YouTube Shorts length and size requirements guide covers the rest, and YouTube Shorts vs TikTok vs Reels compares the platforms strategically.
Instagram Reels specs at a glance (2026)
Size and ratio: 1080 x 1920 pixels, 9:16 vertical; other ratios upload but are padded or cropped.
Length: 3 seconds minimum, 3 minutes maximum in the app; only Reels of 3 minutes or under are recommended to non-followers. Sweet spot for reach: 15 to 60 seconds.
File: MP4 or MOV, H.264 (HEVC also accepted), AAC stereo at 48 kHz, 30 fps standard (23 to 60 accepted), 8 to 12 Mbps. Meta's API spec caps video at 25 Mbps and file size at 300 MB; the app accepts larger files.
Safe zone: keep key content out of the top 14 percent (about 269 px), bottom 35 percent (about 672 px), and 6 percent on each side (about 65 px). Usable area roughly 950 x 979 px.
Cover and caption: 1080 x 1920 cover with the subject inside the central 1080 x 1350; caption up to 2,200 characters with three to five specific hashtags.
What are the most common Instagram Reels size mistakes?
The most common Reels sizing mistake is uploading a horizontal video as-is, so it plays as a small strip with the caption overlapping the picture. Reframe to 9:16 before uploading, by cropping to the subject or placing the clip over a blurred background.
Text under the caption overlay is the second. A hook line in the bottom third is hidden by the username, caption, and audio label. Keep text above the 672-pixel bottom zone, ideally just below the vertical center.
Wrong cover crop is the one you notice on other people's profiles: a headline chopped at the top, a face cut at the chin. Set the cover deliberately, check the grid preview, and keep the subject inside the central 4:5 band.
Going over 3 minutes because the cap allows it costs discovery: a 4-minute Reel is shown to followers only. Cut long content into a series of shorter Reels or keep the long version for YouTube.
Low bitrate and double compression are the quiet killers. A low export, recompressed by a messaging app, then compressed again by Instagram, is the smeared look that makes captions unreadable. Export once at 8 to 12 Mbps, transfer the original file, and upload with the highest-quality setting on.
How do you resize and produce Reels at scale?
The fastest manual route is a 1080 x 1920 project template with a safe-zone guide layer and a caption preset. For one-off fixes, the free tools cover the common cases: the resize video tool converts a 16:9 or 1:1 clip to 9:16 with a blurred or solid background, the crop video tool tightens a horizontal shot onto the subject, the video compressor brings an oversized export down to a Reels-friendly bitrate, and the auto caption generator adds burned-in captions you can position inside the safe zone. That workflow is fine for a handful of Reels a week.
It stops being fine at scale. Posting daily across Instagram, TikTok, and Shorts means dozens of exports a month, each needing the right size, captions in the right place, a cover that survives the grid, and a length under the cap. Vidpal is one way to remove them: it researches trending topics in your niche, writes the script, generates voiceover and visuals, burns in word-level captions positioned inside the Reels safe zone, renders 1080 x 1920 video, and auto-publishes to Instagram Reels, TikTok, YouTube Shorts, Facebook, Pinterest, and X on a schedule. It is built for faceless, high-volume content rather than for editing footage of yourself — if your Reels are talking-head clips, a template plus the free tools is the better fit; if not, the AI Reels generator page shows what the output looks like. Once sizing is handled, the hook and the topic decide whether a Reel travels — our guide to how to go viral on Instagram Reels in 2026 picks up from there.
Frequently Asked Questions
What size should an Instagram Reel be? An Instagram Reel should be 1080 x 1920 pixels, a 9:16 vertical aspect ratio, which fills the full screen in the Reels tab. Upload it as an MP4 or MOV with H.264 video and AAC audio at 30 fps.
How long can an Instagram Reel be in 2026? A Reel can be up to 3 minutes long in the app, a limit Instagram raised from 90 seconds in January 2025, with a 3-second minimum. Meta's API spec allows uploads up to 15 minutes and some accounts have reportedly received longer recording limits, but Instagram states it only recommends Reels of 3 minutes or less to people who do not follow you. For reach, 15 to 60 seconds is the practical sweet spot.
What is the Instagram Reels safe zone? Meta's Reels ad guidance says to keep text, logos, and key creative elements out of the top 14 percent, the bottom 35 percent, and 6 percent on each side of the frame. On a 1080 x 1920 Reel that is roughly 269 pixels at the top, 672 at the bottom, and 65 on each side, leaving a usable area of about 950 x 979 pixels.
What size is an Instagram Reel cover? The Reel cover is 1080 x 1920 pixels, the same 9:16 size as the video. On your profile the grid crops it to a portrait rectangle, in the feed it shows at 4:5, and in some places it can appear square, so keep the subject and any title inside the central 1080 x 1350 area and check the profile grid preview in the cover editor before posting.
Can you upload a horizontal 16:9 video as a Reel? Yes, but it plays as a small strip in the middle of the 9:16 frame with blank space above and below, and the caption overlay sits on top of the picture. Crop the video to 9:16 around the subject or place it over a blurred background so the frame is full.
What is the maximum file size for an Instagram Reel? Meta's published API spec lists a 300 MB maximum for Reels uploaded through the Instagram platform, and the app is widely reported to accept files up to about 1 GB, though Instagram does not publish that figure.
What frame rate and bitrate should a Reel be exported at? Export at 30 fps (or 60 fps if your source is 60), H.264 in an MP4 container, at a variable bitrate of about 8 to 12 Mbps with AAC audio at 48 kHz and 128 to 256 kbps. Meta's API spec accepts 23 to 60 fps and caps video bitrate at 25 Mbps.
The bottom line on Instagram Reels size
Instagram Reels are 1080 x 1920 pixels at 9:16, up to 3 minutes long, exported as MP4 or MOV with H.264 and AAC at 30 fps. Keep essential text and faces out of the top 14 percent and bottom 35 percent of the frame, put the cover's subject in the central 4:5 band, stay under 3 minutes, and export once at a sensible bitrate. The free tools handle resizing, cropping, compressing, and captioning when a clip needs it.
If you are producing Reels every day, Vidpal takes the sizing question off the table. It researches trending topics in your niche, writes a script in your brand voice, generates the AI voiceover, pulls visuals and B-roll, burns in word-level animated captions inside the safe zone, renders a 1080 x 1920 Reel, and auto-publishes to Instagram, TikTok, YouTube Shorts, Facebook, Pinterest, and X, then feeds the analytics back into the next round of topics. There is a free plan to try it on a single account; the pricing page covers the paid plans for volume, and the use cases page shows which niches it suits best.
