Instagram Image Sizes & Aspect Ratios (2026)

Get the Instagram image size wrong and your best photo lands blurry, cropped through someone's face, or squeezed into a tiny sliver of the feed. This is the complete 2026 guide — the exact pixels and aspect ratios for every Instagram format, plus the file specs and safe zones the app never tells you about.

Want to check a crop before it goes live? Our image sizes tool lists the current dimensions, and post preview shows how your image and caption will actually render on the Instagram feed.

The three numbers that cover 90% of posts

If you remember nothing else, remember these:

• 1080 × 1350 (4:5) — feed photos and carousels. The tallest ratio Instagram allows in the feed, so it wins the most screen space.
• 1080 × 1920 (9:16) — Reels and Stories. All vertical video.
• 1080 × 1080 (1:1) — the safe square when you want one file that works everywhere.

Everything below is the detail behind those three. Notice the width never changes: 1080 pixels. Instagram's display width has been 1080px for years, and it's the single most important number in this guide.

1. Instagram feed image sizes

Feed posts (single photos and carousels) accept three aspect ratios:

Use 4:5 portrait by default. It's the tallest the feed allows, so a scrolling thumb spends more time on your post. Landscape (1.91:1) is the weakest choice for reach because it takes up the least vertical space — reserve it for genuinely wide images like panoramas or landscape screenshots.

One catch: the feed grid on your profile still crops everything to a square thumbnail (Instagram has tested taller grid previews, but the square is what most accounts see). So the top and bottom of a 4:5 image get trimmed in the grid view. Keep the core subject centered vertically if the grid look matters to you.

2. Instagram carousel sizes

Carousels use the exact same dimensions as single feed posts — 1080×1350, 1080×1080, or 1080×566. The rule that trips people up:

Every slide in a carousel must share one aspect ratio. Instagram locks the whole carousel to the ratio of the first slide and crops the rest to match.

So if slide one is 4:5 and slide two is a square, slide two gets its sides chopped. Pick a ratio, build all slides to it, and export them at the same pixel size. For seamless "panorama" carousels (one image sliced across several slides), design a single 4:5-per-slide canvas and cut it into equal 1080-wide pieces. Carousels are one of the highest-reach formats on Instagram right now, so this is worth getting right — see our Instagram post ideas for carousel formats that perform.

3. Instagram Reels size

Reels are full-screen vertical: 1080 × 1920 pixels, 9:16. The cover image should also be 1080×1920, but here's the subtle part — the cover shows up cropped to a square (1:1) on your profile grid, while playing full-screen 9:16 in the Reels tab. Put your title text and hook in the vertical center so it survives both crops.

Reels are the format Instagram pushes hardest for reach, so if you're deciding where to spend effort, this is it. Pair the right size with the right timing using our best time to post on Instagram guide.

4. Instagram Stories size

Stories match Reels: 1080 × 1920 pixels, 9:16. The difference is the interface layers on top of your content, so the safe zone matters more here than anywhere else on Instagram.

• Top ~250px: your profile icon and username sit here. Keep it clear.
• Bottom ~250–500px: the "Send message" bar, reply field, and (for public accounts) stickers and link taps live here.
• Middle ~1080 × 1420: the true safe zone. Put all essential text, logos, and CTAs inside it.

If you add a link sticker, poll, or question box, keep the lower third empty so those interactive elements don't overlap your design.

5. Instagram profile picture size

Upload a square image at 320×320 or larger — Instagram downscales it and crops it into a circle. That circular mask is the gotcha: anything in the corners of your square gets cut off. Center your logo or face, and leave breathing room around the edges so nothing important lands in a clipped corner.

6. Instagram ad sizes

Ads run in the same slots as organic content, so the sizes carry over:

For Stories and Reels ads, Meta recommends keeping the top and bottom 14% free of text and logos so the "Sponsored" label and CTA button have room. In practice that's the same safe-zone thinking as organic Stories — build for the middle.

7. Instagram video specs (beyond size)

Pixels are only half the story. The rest of the file matters too:

• Format: MP4 or MOV. MP4 with H.264 is the most reliable.
• Reels length: up to 3 minutes (90 seconds is the sweet spot for completion rate).
• Frame rate: 30fps is standard; 60fps is supported and looks smoother for motion.
• Max file size: aim under ~250 MB for Reels; shorter, tighter files upload and process faster.
• Audio: AAC, stereo, 128kbps+.

Export at 1080×1920 and Instagram won't re-scale your video, which is the main cause of soft, muddy Reels.

8. Instagram photo file specs

For still images, the specs that keep quality high:

• File type: JPG for photos, PNG for graphics with text or flat color.
• Color space: sRGB. If you export in Adobe RGB or ProPhoto, colors shift and look dull after upload.
• File size: keep photos under ~1–2 MB. Bigger files just get compressed harder, not shown sharper.
• Resolution: 1080px wide is the display size. Uploading a 4000px monster gains you nothing and risks heavier compression.

The sweet spot is a 1080-wide JPG in sRGB, saved at high (not maximum) quality — small enough to avoid aggressive compression, large enough to look crisp.

9. Why your Instagram images look blurry (and the fix)

Blur almost always comes from one of two mistakes:

1. You uploaded below 1080px wide. Instagram upscales it to fit, and upscaling is what creates that soft, smeared look. Fix: always export at 1080px wide or more.
2. You uploaded a giant file. A 10 MB, 4000px export gets crushed by Instagram's compression. Fix: export around 1080px wide, under ~2 MB, sRGB.

A third, sneakier cause: wrong aspect ratio. If your image isn't 4:5, 1:1, or 1.91:1, Instagram either crops it or fits it awkwardly — and re-fitting can soften edges. Match the ratio at export time and the problem disappears.

11. Designing once for Instagram and other platforms

If you cross-post, don't redesign from scratch for each network. Two workflows work well:

• Design at the tallest native size (4:5), then crop down. A 1080×1350 canvas crops cleanly to 1:1 for platforms that prefer squares, and the important content stays centered.
• Design at 9:16 for anything that's also going to Reels, Stories, TikTok, or Shorts. Vertical video is interchangeable across all of them — one 1080×1920 export covers the lot.

Just remember Instagram's 4:5 feed sweet spot differs from, say, X's 16:9 and YouTube's 16:9 thumbnails. For the full multi-platform breakdown, see our social media image sizes cheat sheet, and for a repeatable posting process across networks, the creator's guide to cross-platform posting.

12. A 4-step workflow that never posts a bad image

1. Pick the format first — feed (4:5), Reel/Story (9:16), or square (1:1). Decide before you design.
2. Export at the exact pixels — 1080 wide, in sRGB, under ~2 MB for photos.
3. Preview the crop with post preview so you see it the way followers will.
4. Schedule it in Postlia's composer and let it publish at the right time.

Do those four things and "why does this look bad?" stops being a question you ask after hitting share.

Common questions, quick answers

Does Instagram still support square posts? Yes. Squares (1080×1080) work everywhere and are the safest cross-platform size — they just take up less feed space than 4:5.

What about the profile grid crop? The grid trims feed posts to a square thumbnail, so keep the subject vertically centered if your grid aesthetic matters. The full image still shows when tapped.

Can I use a template? Absolutely — build a 1080×1350 and a 1080×1920 template in your design tool of choice and reuse them. Consistent sizing is half of a consistent-looking feed. If you're building out captions and bios to match, our caption writer and Instagram bio generator keep the whole post on-brand.

Ship the right size every time

The Instagram image size rules boil down to three ratios (4:5, 1:1, 9:16), one width (1080px), and one habit: preview before you publish. Get those locked in and image quality stops being something you think about — it's just handled.

When you're ready to post, preview and schedule everything in Postlia, or see the plans if you're managing more than one account. Right size, right ratio, right on time.
