Instagram Portrait vs Square: Post Size for Products

An Instagram portrait post is 1080 × 1350 pixels (4:5) and a square post is 1080 × 1080 pixels (1:1). For most product photos, portrait is the better choice because it is 270 pixels taller at the same width. Landscape is 1080 × 566 (1.91:1); stories and reels use 9:16, which is 1080 × 1920.

Instagram post sizes compared

Instagram's Help Center says photos are shared at up to 1080 pixels wide and keep their shape when the aspect ratio is between 1.91:1 and 4:5, which is 566 to 1350 pixels tall at that width (Instagram Help Center: photo resolution). Meta's developer documentation gives the same 4:5 to 1.91:1 range for feed images and recommends 9:16 for stories and reels to avoid cropping or blank space (Meta for Developers: Instagram media).

The pixel sizes are the ratios worked out at Instagram's 1080-pixel width. You can upload a larger file with the same ratio; Instagram reduces it to 1080 pixels wide.

Portrait or square for product photos?

Choose portrait (4:5) for clothing, kurtis, sarees, bottles and anything taller than it is wide. At 1080 × 1350 it fills more of a phone screen than a square, so the product looks bigger in the feed without any extra cropping.

Choose square (1:1) when the product is compact, such as jewellery, a watch or a box, or when you want one file to work on Instagram, WhatsApp and a marketplace. A square photo needs less planning because the same crop works almost everywhere.

In a carousel, keep every photo in the same shape. Pick portrait or square for the whole set before you export.

What Instagram does with other sizes

A photo wider than 1.91:1 or taller than 4:5 is cropped to fit the supported range, according to the same Help Center page. A tall phone photo (often 3:4 or 9:16) posted to the feed will lose part of its top or bottom. Crop it to 4:5 yourself first, so you decide what stays in the frame.

Do not stretch a square into a portrait

Stretching changes the product's shape. Instead, place the photo on a larger canvas or crop a copy from a larger original. If the garment no longer fits, use a different source photo rather than trimming off the hem.

Keep the full-resolution source so you can make another export later. Enlarging a small screenshot will not recover its missing detail.

Check the preview and your export

The feed, profile grid and full-screen view can show the same image differently. Keep the logo, price and important product features away from the outer edges. In stories and reels, the app's buttons and captions sit over the top and bottom of the screen, so keep text in the middle. Preview the actual post in Instagram before publishing.

Look at the dimensions of the downloaded file rather than assuming that a “portrait” setting always means 4:5. Catalog Pro's available formats are shown in the creation flow; crop a copy if you need another format.

Use the Instagram photography guide to plan the image and the clothing post ideas for useful subjects.

Questions sellers ask

What is the best Instagram post size for clothing?

Portrait, at 1080 × 1350 pixels (4:5). It is the tallest shape the feed keeps without cropping, so kurtis, sarees and other tall garments fill more of a phone screen than they would in a 1080 × 1080 square.

Why does Instagram crop my product photo?

Instagram crops photos wider than 1.91:1 or taller than 4:5 to fit its supported range. A tall phone photo, often 3:4 or 9:16, loses part of its top or bottom in the feed, so crop it to 4:5 yourself first and decide what stays in the frame.

Can I upload a photo larger than 1080 pixels wide to Instagram?

Yes. You can upload a larger file with the same aspect ratio, and Instagram reduces it to 1080 pixels wide. Keep the full-resolution original so you can make another export or crop later.

Should every photo in an Instagram carousel be the same shape?

Yes. Keep every photo in a carousel the same shape, choosing portrait or square for the whole set before you export. Then preview the actual post in Instagram before publishing.
