Which size is best for instagram post 1080*1080 or 1375*1080.
For Instagram posts, the best size depends on your goal:
1080×1080 (square, 1:1 aspect ratio):
Classic Instagram format.
Looks uniform on your feed grid.
Good if you want your profile grid to look neat and balanced.
1080×1350 (portrait/vertical, 4:5 aspect ratio):
Occupies more vertical space on the screen while users scroll—up to 25% more than a square post.
More attention-grabbing and often results in higher engagement for feed posts.
Instagram recommends this 4:5 ratio for portrait images.
Your image will be center-cropped on your profile grid but fully visible in the main feed.
1375×1080 is not a supported Instagram aspect ratio and might get cropped or compressed, resulting in lower image quality or unwanted formatting.
Which aspect ratio enhances engagement more on Instagram, square or portrait.
The portrait aspect ratio (4:5, e.g., 1080×1350 px) enhances engagement more on Instagram compared to the square aspect ratio (1:1, e.g., 1080×1080 px). This is because portrait posts occupy more vertical space on the screen as users scroll, making them more attention-grabbing and visible, which often leads to higher engagement rates. Instagram itself recommends the 4:5 ratio for feed posts to maximize visibility and impact.
In contrast, square posts provide a uniform look for the profile grid but take up less screen space overall, which can result in slightly lower engagement.
So, if your goal is to maximize engagement, choose the portrait aspect ratio 4:5 for your Instagram posts. If you prefer a balanced and neat profile grid appearance, go with the square aspect ratio 1:1.
How does a 1080x1375 post compare in visibility to 1080x1080
A post sized 1080×1375 pixels on Instagram is very close to the more commonly recommended portrait size of 1080×1350 pixels (aspect ratio 4:5). However, 1080×1375 slightly exceeds the typical height Instagram supports for feed posts.
Instagram’s official guidelines and expert sources recommend feed post heights between 566 and 1350 pixels, with the ideal portrait size being 1080×1350 (4:5 ratio). This size maximizes vertical screen space, making your post more visible and engagement-friendly compared to a square 1080×1080 post, which takes up less vertical space.
Using 1080×1375 might cause Instagram to crop or resize the post to fit within its supported aspect ratios, potentially affecting image quality or how it appears in the feed and profile grid. The platform prioritizes aspect ratios between 1.91:1 (landscape) and 4:5 (portrait) to avoid cropping.
In comparison:
1080×1080 (square, 1:1 ratio): Balanced, uniform look on your profile grid but occupies less screen space in the feed, often resulting in slightly lower visibility and engagement.
1080×1350 (portrait, 4:5 ratio): Takes up about 25% more vertical space in the feed, enhances visibility, and typically drives higher engagement.
1080×1375: Slightly taller than Instagram’s recommended max height for posts; may get cropped or resized by Instagram, which can reduce visibility or affect display quality.
Therefore, a 1080×1350 post is preferable to 1080×1375 for optimal visibility and engagement on Instagram, while a 1080×1080 post provides a balanced but less vertically impactful presence.
How do user preferences influence choosing between 1080x1080 and 1375x1080.
User preferences influence the choice between 1080×1080 (square) and 1375×1080 (portrait-like but not standard) Instagram post sizes mainly based on goals for aesthetics, visibility, and engagement:
If users prioritize a balanced and uniform profile grid appearance, they tend to prefer 1080×1080 (square) posts. This size keeps the profile visually neat and consistent when viewed as a whole.
If users want to maximize visibility and engagement in the feed, they prefer portrait dimensions. However, 1375×1080 is not a standard Instagram aspect ratio and may be cropped or resized, reducing display quality. The recommended portrait size is 1080×1350 (4:5 aspect ratio) because it takes up more vertical screen space and attracts more attention.
Users who prefer an optimal balance between engagement and presentation are advised to choose the 1080×1350 portrait size instead of 1375×1080, since 1375 height is beyond Instagram’s official max and might cause issues.
