What Size Should My Instagram Post Be in 2026?
In 2026, use 1080 × 1080 px (square), 1080 × 1350 px (portrait), or 1080 × 566 px (landscape) for feed posts; 1080 × 1920 px for Stories and Reels; at least 320 × 320 px for profile photos; 1080 × 1920 px for highlight covers; and about 420 × 654 px for classic IGTV-style covers. Those targets match how Instagram scales in-app and reduce surprise crops. Batch every size from one upload in the free Social Media Image Resizer.
Instagram Image Sizes for Every Placement
Dimensions below are the industry-standard targets that match Instagram’s primary display widths in the app. Always keep important text and logos inside safe margins—especially on circular crops (profile and highlights).
| Placement | Dimensions | Aspect Ratio | Max File Size |
|---|---|---|---|
| Feed Post (square) | 1080 × 1080 px | 1 : 1 | 8 MB (photo); larger limits for video |
| Feed Post (portrait) | 1080 × 1350 px | 4 : 5 | 8 MB (photo); larger limits for video |
| Feed Post (landscape) | 1080 × 566 px | ≈1.91 : 1 | 8 MB (photo); larger limits for video |
| Stories | 1080 × 1920 px | 9 : 16 | Up to ~30 MB (video); 8 MB typical for still images |
| Reels | 1080 × 1920 px | 9 : 16 | Up to 4 GB (video length limits apply); use full height for cover frames |
| Profile Photo | 320 × 320 px (minimum); higher res recommended | 1 : 1 (cropped to circle) | 8 MB (photo) |
| Highlights Cover | 1080 × 1920 px (design full frame; circle crops center) | 9 : 16 source | 8 MB (photo) |
| IGTV / long-form video cover | 420 × 654 px (classic cover tile); 1080 × 1920 for in-feed video | ≈1 : 1.55 (cover) · 9 : 16 (full-screen) | 8 MB (cover image); video limits separate |
Why Image Size Matters on Instagram
Instagram normalizes uploads to its own pipelines. When your canvas is too small, the app upscales and soft edges; when it is wildly off-ratio, automatic center crops can cut off headlines, product labels, or CTAs you meant to keep visible.
Compression also interacts with resolution. A graphic that already looks crunchy at export will look worse after platform encoding—especially in Stories and Reels, where motion and gradients stress codecs harder than a flat feed card.
Correct sizing keeps more of your original detail through that pipeline, which usually reads as sharper thumbnails, cleaner text, and more confident brand presentation—without buying extra reach.
Resize Your Image to the Right Size Instantly
ConvertPal’s Social Media Image Resizer runs in your browser: upload a JPG, PNG, or WebP, pick Instagram (and other network) presets, and download a ZIP of correctly sized JPEGs—ideal when you need feed, story, and reel variants from one master asset. No account wall; your file stays local while presets apply center-crop cover fits so each slot is exactly the target width and height.
Frequently Asked Questions
- What is the best size for an Instagram post in 2026?
- For single-image feed posts, start from a 1080 px wide canvas: 1080 × 1080 for square, 1080 × 1350 for portrait (4:5), or 1080 × 566 for landscape. That width matches how Instagram scales on most phones, so you avoid unnecessary upscaling. If you are batching variants, the Social Media Image Resizer can output each preset in one go.
- Will Instagram crop my image if it's the wrong size?
- Usually yes. Non-standard aspect ratios are fit into each surface’s frame: feed items may letterbox or center-crop depending on viewer and device, while Stories and Reels assume a tall 9:16 canvas. If your photo is wider than the slot allows, Instagram may crop the sides; if it is too tall or too short, it may crop top and bottom or add bars. Designing to the official target ratios keeps your subject and typography inside the safe area you intend.
- What's the difference between Instagram portrait and landscape?
- Portrait feed posts use a 4:5 frame (1080 × 1350), so they occupy more vertical space in the home grid and can feel more immersive. Landscape posts use a wider ~1.91:1 frame (1080 × 566), which reads more cinematic but shorter in the feed. Neither is “better”—pick the ratio that matches your creative, then keep logos and faces away from crop edges.
- What resolution should Instagram images be?
- Aim for 1080 px on the long edge for feed, Stories, and Reels stills unless you have a deliberate reason to go higher. Ultra-high megapixel uploads are often downscaled anyway, which wastes upload time without visible gain. For profile photos, upload at least 320 × 320 (square), but many teams export 1080 × 1080 and let Instagram downscale for a sharper source file.
- Can I use the same image size for Stories and Reels?
- For static frames and vertical video, 1080 × 1920 (9:16) is the shared target, so one correctly sized vertical master can cover both placements. Reels as a product also includes motion, audio, and duration rules that still images do not—but the pixel canvas matches Stories. If you are exporting templates, keep key art in the central “safe” band so UI overlays (profile chip, like count) do not cover critical text.
