Instagram Image Sizes in 2026 — Post, Story, Reel, and Profile Dimensions

Square: 1080 x 1080 pixels (1:1). The classic Instagram format. Still works perfectly and takes up the most screen space in the feed. Portrait: 1080 x 1350 pixels (4:5). This is the maximum vertical size Instagram allows in the feed, and it takes up the most screen real estate of any format. If you want maximum attention, use 4:5. Landscape: 1080 x 566 pixels (1.91:1). Landscape photos get displayed smaller in the feed, so they're less attention-grabbing. Avoid unless the composition specifically requires it.

The minimum width Instagram accepts is 320 pixels, but anything below 1080 wide gets upscaled and looks soft. Always upload at 1080 pixels wide. Your image resizer should have Instagram presets built in — pick the one matching your post type.

Both Stories and Reels use the same dimensions: 1080 x 1920 pixels (9:16 full screen). This is standard phone screen size. If your image or video doesn't fill this ratio, Instagram will add blurred bars on the sides or top/bottom. It looks amateur — always resize to fill the full 9:16 frame.

Keep critical content (text, faces, product details) within the centre 80% of the frame. The top and bottom edges get obscured by the username bar and action buttons. Nothing important should be in the top 100 pixels or bottom 200 pixels.

Instagram profile pictures are stored at 320 x 320 pixels and displayed in a circle. Upload at least 320 x 320 (larger is fine — Instagram downscales). Like WhatsApp, crop to a square first and keep important elements in the centre circle.

Carousel slides must all be the same aspect ratio. Instagram sets the ratio based on your first image and forces every subsequent image to match. If your first image is 1:1, all slides will be cropped to 1:1. Plan your carousel before uploading — crop all images to the same ratio beforehand.

Instagram accepts JPG and PNG. For photos, JPG at 85-95% quality is ideal — the file is small enough to upload quickly, and Instagram's compression won't degrade it much further. For graphics with text or sharp lines, PNG preserves crispness better. Avoid uploading images over 10 MB — Instagram compresses them more aggressively, which can introduce visible artifacts.

Quick reference: Feed square: 1080 x 1080. Feed portrait: 1080 x 1350. Feed landscape: 1080 x 566. Story/Reel: 1080 x 1920. Profile: 320 x 320. Always JPG at 85%+ quality. Always 1080px wide minimum.

Instagram re-compresses every image you upload, regardless of the quality you start with. The platform strips EXIF data, re-encodes to its own JPEG quality level, and sometimes noticeably reduces sharpness. To minimise quality loss, upload images that are exactly the recommended pixel dimensions — no larger. Oversized images get downscaled by Instagram's algorithm before compression, which means they go through two rounds of quality reduction.

Colour accuracy also shifts slightly after upload. If exact colour matching matters (for product photos, brand posts, or artwork), check how the image looks after posting and adjust your source file's saturation and contrast slightly to compensate. Most users will never notice this shift, but photographers and designers often find it worth the extra step.

If you are creating content for a brand or business account, you often need the same image in multiple sizes — square for the feed, vertical for Stories, and a different crop for the profile picture. Rather than cropping from the same photo three times, plan your composition with safe zones. Keep the main subject centred in the frame with enough space around it so that any crop ratio (1:1, 4:5, 9:16) captures the key elements without cutting anything important.

The biggest mistake people make is uploading photos straight from their camera without resizing. Modern phone cameras shoot at 12-108 megapixels, which is far more than Instagram uses. When Instagram receives an oversized image, it recompresses and downscales it using its own algorithm — which often produces softer results than if you'd done it yourself.

The solution: resize before uploading. Open an image resizer and set the width to 1080 pixels. For portrait posts (which take up the most feed space and generally perform best), set the height to 1350. For square posts, set both to 1080. Save as JPEG at 85-95% quality — this gives you a clean file that Instagram barely needs to recompress.

Instagram applies JPEG compression to every uploaded photo, typically reducing quality to around 70-75% equivalent. This is why photos sometimes look slightly washed out or lose fine detail after posting. You can't prevent this compression entirely, but you can minimize its impact.

Three strategies that help: 1) Upload at exactly the target dimensions (no larger). 2) Avoid uploading PNG screenshots or graphics with sharp text — convert these to high-quality JPEG first using a PNG to JPG converter, as Instagram handles JPEG-to-JPEG compression more gracefully than PNG-to-JPEG. 3) Avoid uploading through WhatsApp or other messaging apps first, as they apply their own compression before you even get to Instagram.

If you're a content creator posting multiple times per week, resizing each image individually gets tedious. Consider setting up a workflow: edit your photos in your preferred editor, export them at 1080 pixels wide, and save in a dedicated "Instagram Ready" folder. This way, every image is already optimized before you open the Instagram app.

For product photos, food photography, or any images where fine detail matters, export at slightly higher quality (90-95% JPEG) and let Instagram handle the final compression. For text-heavy graphics like quotes or infographics, PNG often retains crispness better — but keep the file under 20 MB to avoid upload issues.

Story/Reel: 1080 × 1920 px. Profile picture: 320 × 320 px (upload at 400+ for sharpness). Carousel: All slides same ratio, first slide sets it.

One final tip: Instagram's algorithm doesn't care about image dimensions — it cares about engagement. But properly sized, sharp images get more engagement because they look professional and are easier to view. Getting your dimensions right is the minimum standard; your content quality is what drives actual performance.
