The best Instagram post size for high-quality images is 1080 × 1080 pixels (square, 1:1). For portrait posts, use 1080 × 1350 pixels (4:5) to take more screen space. For landscape posts, 1080 × 566 pixels (1.91:1) works best.

In 2026, the best size for Instagram posts that are of high quality is the Portrait format at 1080 x 1350 pixels (4:5 aspect ratio) because it takes up the most vertical space on the screen and results in higher engagement. To have a perfectly optimized profile, the new Tall format at 1080 x 1440 pixels (3:4 aspect ratio) is also very much recommended, as it corresponds with the updated grid preview before going for the crazy cropping. No matter what ratio you choose, always make sure your width is exactly 1080 pixels to keep the images crisp and to avoid over-compression.

The best post size for high-quality posts on Instagram depends on the format. For square posts, use 1080 × 1080 pixels (1:1 ratio). For portrait (which takes up more screen space and usually gets better engagement), use 1080 × 1350 pixels (4:5 ratio). For landscape posts, use 1080 × 566 pixels (1.91:1 ratio). Always upload images in JPG or PNG format with the width set to 1080 pixels to maintain clarity. Using the correct size prevents cropping, keeps your images sharp, and ensures your posts look professional in the feed.
