Instagram Image Sizes in 2026: The Complete Cheat Sheet

By the Duvora Tools team · November 7, 2026 · 6 min read · How we write our guides

For most Instagram feed posts in 2026, use 1080 × 1350 px (4:5) or 1080 × 1440 px (3:4). Stories and Reels are 1080 × 1920 px (9:16), and your profile photo should be at least 320 × 320 px. The bigger change in the last year is the profile grid: it now shows taller 3:4 thumbnails instead of squares, so the size you post affects how your grid looks.

Instagram sizes at a glance

Resize any photo to these exact sizes in one click with the social media image resizer. It runs in your browser, so your photos are never uploaded.

The 3:4 profile grid change

Instagram's profile grid used to show square thumbnails. In 2025 it switched to taller 3:4 rectangles. That means:

• Square (1:1) posts lose a quarter of their width on the grid: on a 1080 px square, about 135 px is hidden from each side.
• 4:5 posts are slightly wider than a 3:4 tile, so a thin strip — about 34 px on each side of a 1080 × 1350 image — is hidden on the grid. They still show in full in the feed.
• 3:4 posts (1080 × 1440) show uncropped on the grid.

Guides disagree on whether 4:5 or 3:4 is the "best" default, and Instagram changes how it displays posts from time to time. A practical rule: if your grid is part of your brand (artists, photographers, shops, aesthetic accounts), post in 3:4. If you care most about how posts look in the feed, 4:5 remains a safe choice. Either way, keep faces, logos and text away from the left and right edges.

Feed posts: which shape to use

Portrait (4:5 or 3:4)

Portrait images take up the most space on a phone screen as people scroll, which gives them more attention than squares or landscapes. For almost all photos, product shots and text graphics, portrait is the best choice.

Square (1:1)

Still supported and fine for graphics designed as squares, but they now appear cropped on the profile grid and smaller in the feed.

Landscape (1.91:1)

Wide images appear small in the feed. Use them only when the scene really needs the width, such as a panorama — or split a panorama across a carousel instead.

Carousel sizes

All slides in a carousel use the aspect ratio of the first slide. If your first image is 4:5 and a later one is square, the later one is cropped or padded to match. Prepare every slide at the same size before uploading. Carousels can include up to 20 photos and videos.

Stories and Reels

Both are full-screen vertical: 1080 × 1920 px. Instagram's buttons, profile name and caption cover parts of the screen, so keep important text and faces out of the top and bottom ~250 px and away from the right edge on Reels, where the like and share buttons sit.

Your Reel cover is shown at 9:16 in the Reels tab but cropped to 3:4 on your profile grid. Put the title and face in the centre of the cover so both versions look right.

Profile picture

Upload a square image of at least 320 × 320 px (larger is fine; Instagram scales it down). It's displayed as a small circle, so the corners are cut off. Use a close crop of your face or a simple logo with plenty of space around it.

File types and quality tips

• Use JPG for photos and PNG for graphics with text. Instagram re-compresses everything, so starting with a clean, correctly sized image gives the best result.
• Upload at 1080 px wide. Larger images are downscaled by Instagram, which can soften them. Resizing yourself gives you control over the crop.
• Keep files reasonably small. If an image is several megabytes, shrink it with the image compressor before uploading; it's quicker on mobile data and avoids heavy re-compression.
• Turn on high-quality uploads. In Instagram's settings, under data or media quality, enable the option to upload at the highest quality so your images aren't compressed further on slow connections.
• Check text legibility on a phone. Text that looks fine on a laptop can be tiny in the feed.

Video specs in brief

How to resize a photo for Instagram in four steps

1. Open the image resizer and choose your photo. It loads instantly and stays on your device.
2. Pick a preset: Instagram portrait post – 1080×1350, Instagram grid-fit post (3:4) – 1080×1440, or Instagram Story / Reel – 1080×1920.
3. Choose Crop to fill for a full-bleed image and adjust the crop position if a face or product is near an edge. For a photo you don't want cropped at all, choose Fit with blurred background — a popular look for Stories.
4. Download as JPG and upload to Instagram. If the file is still large, run it through the compressor at around 80% quality.

Designing one image that works everywhere

Most creators post the same visual in several places: the feed, the profile grid, a Story to promote it, and sometimes Facebook. A few habits make that painless:

• Design at 1080 × 1440 if the grid matters. It shows fully on the grid, and in the feed it appears as a tall portrait post.
• Keep a centre safe zone. If you design at 4:5, keep important elements at least 40 px in from the left and right so the grid's 3:4 crop doesn't touch them.
• For Stories, place the feed image on a 1080 × 1920 canvas with a blurred or brand-colour background, rather than stretching it. This also leaves room for stickers and the "new post" link.
• Use consistent margins and fonts across your graphics. A tidy grid makes profile visitors more likely to follow.

Carousel design tips

Carousels often get more reach than single images because people swipe and return to them. To make them work:

• Make the first slide a hook — a bold claim, a question or a striking photo — because it's the only slide shown in the feed and on the grid.
• Use the same size for every slide; 1080 × 1350 or 1080 × 1440 are both good choices.
• For tutorials and tips, keep one idea per slide and finish with a slide that asks people to save or share.
• For a seamless panorama, split a wide image into equal portrait slices so it scrolls as one picture.

Accessibility: add alt text

When you post, open Advanced settings and write custom alt text describing the image. Screen readers read it to people with visual impairments, and Instagram uses it to understand your content, which can help your post appear in search. Keep it short and specific: "Woman pouring latte art in a white cup at a café counter" is far more useful than "photo".

Sizes for the rest of Meta

If you cross-post, Facebook feed posts work well at 1080 × 1350, Facebook Stories at 1080 × 1920, and link-share images at 1200 × 630. Threads displays most portrait and square images without problems, so your Instagram files can usually be reused as they are.

Common mistakes

• Posting screenshots at random sizes — they get cropped unpredictably. Resize first.
• Text near the edges — it gets trimmed on the grid or hidden behind buttons.
• Mixing ratios in a carousel — later slides get cropped.
• Tiny profile photos with detailed logos — simplify for the small circle.
