The best Instagram post size in 2026 is 1080 x 1350 px (4:5 portrait) for feed posts, 1080 x 1920 px (9:16) for Stories and Reels, and 1080 x 1080 px (1:1) for square images. Instagram’s profile grid now crops previews to 3:4, so keep faces, text, and logos inside that taller safe zone. Upload at 1080 px wide as JPG or PNG, and MP4 (H.264 + AAC) for video.
Your post looked perfect in Canva. Then Instagram cropped the headline off the top, pushed your face behind the caption, and turned your clean grid into a patchwork of mismatched thumbnails.
Wrong dimensions don’t just look sloppy. They quietly cost you reach. A cropped hook kills the swipe, a chopped face weakens the first impression, and an inconsistent grid makes profile visitors bounce before they follow.
This guide gives you every Instagram size that matters in 2026: feed posts, the new 3:4 grid, Stories, Reels, carousels, and profile photos. Exact pixels, aspect ratios, file limits, and the safe zones that keep your content from getting cut.
Key Takeaways
- Best all-round feed size: 1080 x 1350 px (4:5) for in-feed; 1080 x 1440 px (3:4) if you want zero grid cropping.
- Grid crops to 3:4: The profile grid previews posts at roughly 3:4, even though the feed shows up to 4:5 (Oktopost, Hootsuite, as of May 2026).
- Stories & Reels: 1080 x 1920 px (9:16), full screen.
- Carousels: Up to 20 slides; the first slide locks the aspect ratio. You can reorder slides after publishing.
- Profile photo: Upload 320 x 320 px minimum (1:1); displays as a small circle.
- Standard width is 1080 px. Smaller uploads look blurry; larger ones get compressed.
- File specs: JPG/PNG for images, MP4 (H.264 + AAC) for video. Keep images under 10 MB, Reels under 500 MB.
Quick Answer: Instagram Sizes at a Glance (2026)
Every dimension below is width x height in pixels.
- Square feed post: 1080 x 1080 px (1:1)
- Portrait feed post: 1080 x 1350 px (4:5)
- Tall feed post: 1080 x 1440 px (3:4)
- Landscape feed post: 1080 x 566 px (1.91:1)
- Stories: 1080 x 1920 px (9:16)
- Reels (and Reel covers): 1080 x 1920 px (9:16)
- Carousel: 1080 x 1350 px or 1080 x 1440 px (match the first slide)
- Profile photo: 320 x 320 px minimum (1:1)
- Highlight cover: 1080 x 1920 px or 1080 x 1080 px
How Instagram Sizes Actually Work (Aspect Ratio vs Resolution)
Two terms decide whether your content fits: aspect ratio and resolution.
Aspect ratio is the proportion of width to height. A 4:5 ratio means the image is 4 units wide for every 5 units tall. Instagram supports these ratios:
- 1:1 (square) — feed posts
- 4:5 (portrait) — feed posts
- 3:4 (tall portrait) — feed posts
- 1.91:1 (landscape) — feed posts and ads
- 9:16 (vertical) — Stories and Reels
Resolution is the pixel count. An image at 1080 x 1350 is 1080 pixels wide and 1350 pixels tall. The standard upload width across Instagram is 1080 px. Go wider and Instagram scales it down anyway; go narrower and it looks soft or pixelated on modern phone screens.
Feed View vs Grid View: The Crop That Catches People Out
What people see in the feed is not always what shows on your profile grid. The feed displays posts up to 4:5 tall, but grid thumbnails crop to roughly 3:4 (Oktopost, as of May 2026). If your key elements (a face, a headline, a logo) sit near the top or bottom of a 4:5 post, the grid preview can chop them off.
The fix: design inside a 3:4 safe zone, centered in your canvas, so the post looks intentional in both views.

| Highlight cover | 1:1 or 9:16 | 1080 x 1080 or 1080 x 1920 px | Circular crop | PNG/JPG | Match your brand palette |
Instagram Feed Post Size (Photos & Single Videos)
Feed posts support four ratios in 2026: 1:1 square, 4:5 and 3:4 portrait, and 1.91:1 landscape. Portrait takes the most screen space, which is why most creators default to it.
Square Feed Posts (1:1)
The square post is 1080 x 1080 px. It crops cleanly into the grid and behaves predictably everywhere.
Square works best for:
- Text-based graphics and quotes
- Centered product shots or headshots
- Logos and symmetrical designs
- Announcements
Center your key content and leave 60-80 px of padding from each edge to protect against minor device cropping.
Portrait Feed Posts (4:5)
Portrait is 1080 x 1350 px (4:5), the most screen real estate Instagram gives a standard feed photo. More vertical space means more attention as people scroll.
The catch: the grid crops closer to 3:4, so keep faces, text, and key details centered inside a 3:4 safe zone.
Portrait works best for:
- Outfit and fashion photos
- Vertical product shots
- Infographics and step-by-step tutorials
- Portrait photography
The New 3:4 Feed Post (1080 x 1440 px)
Instagram added a 3:4 ratio (1080 x 1440 px) for feed posts to match how the grid trims taller content. It is slightly taller than 4:5 and lines up exactly with the grid crop.
Use 3:4 when you want to:
- Eliminate grid-preview surprises entirely
- Maximize vertical space
- Keep a cohesive, uniform profile aesthetic
- Cross-post cleanly to Pinterest
Landscape Feed Posts (1.91:1)
Landscape is 1080 x 566 px (1.91:1), mainly used for wide shots and ads.
It suits:
- Cinematic travel and panoramic scenes
- Group photos
- Dashboard or screen recordings
Keep important text centered horizontally. If your source is wider than 1.91:1, crop it manually before uploading rather than trusting Instagram’s auto-crop.
Instagram Carousel Size (Multi-Image & Multi-Video)
Carousels hold up to 20 photos and videos in a single post, and they earn the highest engagement of any format in 2026 (SocialInsider, as of May 2026). Instagram locks the aspect ratio to your first slide, so set the ratio there and design every other slide to match.
Recommended carousel sizes:
- 1080 x 1350 px or 1080 x 1440 px for educational and text-heavy content
- 1080 x 1080 px for product catalogs
A 2024 update lets you mix orientations in one carousel, but Instagram fills the mismatched space with borders, so it rarely looks clean. Keep margins, type, and color consistent across slides for a cohesive swipe.
2026 update: You can now reorder and replace carousel slides after publishing. Useful for fixing mistakes, but design your sequence so a reshuffle never breaks the narrative.
For slide-by-slide design, hooks, and CTA placement, see our Instagram carousel best practices guide.
Instagram Story Size (9:16)
Instagram Stories are full-screen vertical content at 1080 x 1920 px (9:16). Any resolution with the same ratio works, but 1080 width keeps it sharp on modern phones.
Stories safe zone:
- Leave roughly 250 px clear at the top and bottom for the profile bar, reply box, and UI
- Keep core text and faces inside the central 1080 x 1420 px band
Instagram Reels Size (Video & Covers)
Reels use a full-screen 9:16 frame at 1080 x 1920 px, but they appear differently depending on where they show up. In the Reels feed and tab they fill the screen; on your profile grid the thumbnail crops to 4:5 (or 3:4).
That split is why safe zones matter most for Reels:
- Make both the Reel and its cover 1080 x 1920 px
- Keep faces, titles, and subtitles inside the central 1080 x 1350 px area
- Avoid eye-catching elements in the top or bottom 15%, where captions and controls sit
- Use high text-to-background contrast so the cover reads at thumbnail size
You can update a Reel cover weeks later to refresh your grid without reposting.
Pro tip: Build a reusable Canva or Figma template with guides for the full 9:16 frame plus 4:5 and 3:4 preview crops. You design once and never guess a safe zone again. For the full posting cadence, see how to schedule Instagram posts.
Instagram Profile Photo Size
Upload your profile photo at 320 x 320 px minimum (1:1). It displays as a small circle (~110 px), so center the important part.
Profile photo best practices:
- Headshot? Use a solid or on-brand gradient background so it pops in the feed
- Logo? Upload a PNG for crisp edges
- Photo? Upload a JPG
- Avoid frequent drastic changes; recognition is what earns the follow-back
Highlight Cover Size
Highlight covers appear as circles at the top of your profile and shape first impressions.
- Use 1080 x 1920 px Story slides or dedicated 1080 x 1080 px squares
- Center icons and text with generous padding (the circle crops the edges)
- Keep colors, icon style, and type consistent across the set
- Export PNG for flat graphics, JPG for photos, well under 1 MB
File Formats, Quality & Size Limits (2026)
Images:
- JPG/JPEG for photos and gradients (80-90% quality)
- PNG for logos, flat illustrations, and text-heavy graphics
- Skip GIFs for feed posts; use MP4 for motion
Video:
- MP4 (H.264 + AAC) is the standard for every video format
- MOV is supported but produces larger files
Limits:
| Content Type | Hard Limit | Best Practice |
|---|---|---|
| Images | ~30 MB | Under 10 MB |
| Feed video & Reels | 4 GB | Under 500 MB |
| Reel length | Up to ~3 min in the main tab | Under 90 sec for most niches |
| Story segment | 60 seconds | Split longer clips into segments |
Safe Zones, Format by Format
A safe zone is the part of the frame that won’t be covered by UI or cropped in previews.
Feed posts: Keep text and logos 90-120 px from every edge. Design for the 3:4 grid crop.
Reels: Captions and buttons overlay the bottom 15-20%. Keep subtitles above the centerline.
Stories: The username bar (top) and reply bar (bottom) eat the outer ~15%. Keep content in the central band.
Profile and highlight covers: Think in circles. Keep everything inside the central 60-70% radius.
Right Size Is Step One. Reach Is Step Two.
Perfect dimensions stop Instagram from cropping your work. They don’t, on their own, turn views into customers.
Here is where most creators leak revenue: a post lands, people comment “info” or “link,” and the creator replies hours later when the moment has passed. The attention was there. The follow-through wasn’t.
That’s the gap CreatorFlow closes. Set a trigger word, write your message, and every comment gets an instant DM with your link, lead magnet, or booking page, automatically, 24/7. Correctly sized content earns the swipe and the comment; DM automation converts that comment while the interest is hot.
It runs on Meta’s official Instagram API, costs a flat $15/month with no per-contact fees, and takes minutes to set up. Pair it with a clean grid and you have the full loop: content that gets seen, and a system that converts the people who engage.

FAQ
What is the best Instagram post size in 2026?
1080 x 1350 px (4:5) for in-feed impact, or 1080 x 1440 px (3:4) if you want the post to match the grid crop with zero cropping. Both maximize vertical space while keeping key content inside the 3:4 safe zone.
Is the Instagram grid 4:5 or 3:4?
The grid previews thumbnails at roughly 3:4, while the feed displays full posts up to 4:5. Post at 4:5 or 3:4, but keep faces, text, and logos inside the 3:4 area so nothing gets cut in the grid (Oktopost, Hootsuite, as of May 2026).
What size should Instagram Stories be?
1080 x 1920 px (9:16). This fills the screen with no borders. Leave about 250 px clear at the top and bottom for the UI.
What size should Instagram Reels be?
1080 x 1920 px (9:16) for both the video and the cover. Keep important elements centered, since the grid thumbnail crops to roughly 4:5.
What dimensions should my Instagram profile picture be?
Upload at least 320 x 320 px (1:1). It displays as a small circle, so center key elements within the inner 60-70%.
How many slides can an Instagram carousel have?
Up to 20. The first slide sets the aspect ratio for the whole carousel, and you can reorder or replace slides after publishing.
What is the maximum file size for Instagram posts?
Images cap around 30 MB and videos at 4 GB. As a best practice, keep images under 10 MB and Reels under 500 MB to avoid heavy compression and slow uploads.
Why does Instagram crop or blur my posts?
Blur usually means you uploaded below 1080 px wide, so Instagram upscaled it. Cropping happens when your aspect ratio falls outside the supported range (1.91:1 to 3:4 for feed) or when key content sits outside the 3:4 grid safe zone. Export at 1080 px wide in a supported ratio to fix both.
