Instagram product photos: 1080 is not a suggestion
Instagram compresses everything you upload. That is the whole story, and understanding it changes how you export.
The rules, exactly
- Square feed post. 1080 x 1080 pixels. This is the native size Instagram serves.
- Portrait. 1080 x 1350, the 4:5 ratio, occupies the most vertical space in the feed and therefore the most attention.
- Stories and Reels. 1080 x 1920, the 9:16 ratio.
- Format. JPEG, sRGB. Instagram converts whatever you give it anyway.
Why bigger is worse, not better
Upload a 4000 pixel image and Instagram does not thank you for the detail. It resamples down to 1080 with its own compression, and its resampler is tuned for speed, not for edges. Product photos suffer worst, because they are the one thing on Instagram made of hard edges against a flat background, which is exactly what aggressive compression turns to mush. Export at exactly 1080 yourself, with a good resampler, and Instagram has almost nothing left to do. The difference is visible on any product with a fine outline.
Tips for selling, not just posting
- White backgrounds make a grid. Nine white-background product posts in a row turn a profile into a shop window. This is the cheapest branding available to a small seller.
- 4:5 for reach, 1:1 for the grid. Portrait takes more screen and gets more attention in the feed. Square keeps the profile grid tidy. Many sellers post 4:5 and accept the grid crop.
- The first frame of a carousel is the whole decision. Clean white hero first, lifestyle after.
- Do not add text to the product image. Put it in the caption where it can be read, searched and translated.
The fastest way
Choose the Instagram 1080 preset. The cutout is resampled once, properly, at export, and lands at exactly 1080 x 1080 on white. Instagram receives a file it has no reason to touch.
