Instagram post sizes 2026: portrait, square, landscape and story
Art'st Studio · Updated: · Türkçe oku
If the edges of a photo you uploaded to Instagram got cut off, or the image turned blurry, the cause is usually the size. Instagram accepts specific aspect ratios for each post type, and anything outside those ratios gets cropped or scaled by Instagram itself.
This guide covers Instagram post sizes for 2026, when each one works best, and how to bring a product photo to the right size step by step without cutting the product off.
Quick answer: Instagram post dimensions
- Portrait post (4:5): 1080 x 1350 px. Takes up the most space in the feed.
- Square post (1:1): 1080 x 1080 px. Classic and safe everywhere.
- Landscape post (1.91:1): 1080 x 566 px. For scenery and wide product layouts.
- Story and Reels (9:16): 1080 x 1920 px. Full-screen vertical.
Instagram displays images 1080 px wide. Upload something larger and it is scaled down; upload something smaller and it is scaled up, which causes blur. So start with an image at least 1080 px wide.
The profile grid and the 3:4 view
In 2025 Instagram changed the profile grid: posts on your profile now appear as vertical 3:4 previews instead of squares. That means a thin strip at the top and bottom of a 4:5 post is hidden on the grid, and the sides of a square post are trimmed.
The practical takeaway: put the product in the middle of the frame and keep important text away from the edges. The full post shows when someone opens it, but the grid makes the first impression.
Which size should you choose?
Portrait post (4:5)
Usually the best choice for product photos. It fills more of the screen in the feed and catches the eye while scrolling. Most vertical phone photos fit this ratio with a small crop.
Square post (1:1)
A safe choice when the product sits in the middle of a plain background, or when you want a catalogue look. It takes up slightly less space than portrait.
Landscape post (1.91:1)
Good for a wide table setup, several products side by side, or a shot of your shop. It looks small in the feed, so it is rarely the best pick for a single product.
Story (9:16)
Stories are full-screen vertical. The profile name and reply bar cover the top and bottom, so keep key content in the middle. See Instagram story size for the safe zones.
Step by step: resizing without cutting the product
- Check the photo's ratio. Divide width by height: below 0.6 is closest to a story, 0.6 to 1 to a portrait post, above 1.3 to a landscape post.
- Find where the product is. A crop must not cut the product; it should stay near the centre of the frame.
- If the ratio is close to the target, crop: a thin strip goes from the edges and the product is untouched.
- If the ratio is very different, add space instead of cropping. Filling the edges with a blurred copy of the same photo or a matching colour beats cutting the product off.
- Bring the image to 1080 px wide and save it as JPEG. Instagram's official publishing interface requires JPEG and rejects files over 8 MB.
- Check the preview before posting: is the product centred, is any text readable?
If you'd rather not do this by hand, our free Instagram resizer converts the photo in your browser, suggests a format from its ratio and keeps the product centred. The image is not uploaded anywhere.
Avoiding blur and colour loss
- Don't upload tiny images: anything under 1080 px wide gets upscaled and softens.
- Don't re-save repeatedly: a JPEG loses a little quality every time it is opened and saved. Export once from the original.
- Watch the colour profile: some cameras and design apps save in a wide colour space. Instagram converts to sRGB and colours can look dull. Choose sRGB when exporting.
- HEIC photos: iPhone photos may be HEIC. If uploading from a computer fails, see how to upload HEIC photos to Instagram.
Sizes in carousels
In a post with several images, the first image's ratio sets the ratio for the whole carousel. If the first image is portrait, the rest are cropped to portrait too. Bring every image to the same ratio before you start, or some products may lose their edges.
Sizes for other platforms
If you share the same product on Facebook, X, LinkedIn or YouTube, each platform has its own ratio: X and YouTube favour wide 16:9 images, LinkedIn handles square and landscape well, and Facebook is happy with 4:5 or square. Alongside the format you pick for Instagram, Vitrin prepares separate copies sized for the other platforms, so one upload covers every channel.
A quick checklist before you post
- Width is at least 1080 px.
- The ratio matches the format you picked.
- The product sits in the centre, clear of the grid's trimmed edges.
- The file is a JPEG under 8 MB in sRGB.
- Any text on the image is readable on a phone screen.
Frequently asked questions
What is the best Instagram post size?
For product photos the 4:5 portrait size (1080 x 1350 px) is usually best because it takes up the most space in the feed. Square works well when the product sits centred on a plain background.
Why does Instagram make my photo blurry?
Usually the image is narrower than 1080 px and gets upscaled, or a JPEG that has been compressed many times is uploaded. Export once from the original at 1080 px wide and high quality.
Why are my posts cropped on my profile grid?
Since 2025 Instagram shows 3:4 portrait previews on the profile grid. A thin strip of square and 4:5 posts is hidden on the grid; the full image shows when the post is opened.
Can a carousel mix different aspect ratios?
No. The first image sets the ratio for the whole carousel and the rest are cropped to it. Bring every image to the same ratio before you start.
Which file format does Instagram accept?
The app converts many formats itself, but the official publishing interface accepts only JPEG and rejects files over 8 MB. If you use a posting tool, the image must be a JPEG.
