Instagram Image Sizes Guide 2026 — Every Format Explained

Getting your Instagram image sizes wrong means cropped heads, blurry text, and wasted effort. This guide covers every Instagram format with the exact pixel dimensions you need in 2026.

Quick Reference Table

Square Posts (1080 x 1080)

The classic Instagram format. Square posts still perform well in 2026 because they take up consistent space in the grid and look clean on profile pages.

When to use square:

• Product photos on a clean background
• Quotes and text-based graphics
• Before-and-after comparisons using a horizontal merge
• Logo reveals and brand announcements

Pro tip: Use the photo collage maker to create a 2x2 grid that fits perfectly in the 1080 x 1080 format.

Portrait Posts (1080 x 1350)

Portrait posts take up more screen real estate in the feed, which means more attention and typically higher engagement.

When to use portrait:

• Full-body photos
• Infographics and step-by-step guides
• Tall product shots (bottles, dresses, furniture)
• Vertical before-and-after comparisons using a vertical merge

Important: Instagram will crop portrait images in the grid view to 1:1. Make sure the most important content is centered.

Landscape Posts (1080 x 566)

Landscape posts are the least common on Instagram because they take up the smallest amount of feed space. Use them sparingly.

When landscape works:

• Panoramic shots
• Wide group photos
• Cinematic screenshots
• Side-by-side product comparisons

Stories and Reels (1080 x 1920)

Stories and Reels use the full phone screen at 9:16 aspect ratio. This is the most consumed format on Instagram in 2026.

Design tips:

• Keep text within the center 80% of the frame — top and bottom are covered by UI elements
• Use bold, readable fonts (minimum 24pt equivalent)
• Place CTAs in the middle third of the screen
• Leave space at the top for your profile picture and username overlay

Creating story-sized images: Merge photos vertically using mergeimages.net and resize to 1080 x 1920 for perfect story dimensions.

Carousel Posts

Carousels let you share up to 20 images in a single post. All images in a carousel must use the same aspect ratio — either 1:1 or 4:5.

Carousel best practices:

• First slide should hook attention (it appears in the feed)
• Use consistent design across all slides
• End with a CTA slide
• 4:5 portrait ratio gets more engagement than 1:1

Creating carousel slides: Use the photo collage maker to combine multiple images into a single carousel slide. This works great for comparison posts or multi-product features.

Profile Pictures (320 x 320)

Instagram profile pictures display as circles. The uploaded file should be at least 320 x 320 pixels, but uploading at 720 x 720 or higher ensures crispness on all devices.

Tips for a great profile picture:

• Center the subject (face or logo) — edges will be cropped into a circle
• Use a solid or simple background
• Keep it recognizable at thumbnail size
• Use the profile picture maker to crop and optimize your photo

Highlight Covers (1080 x 1920)

Highlight covers use the same 9:16 ratio as stories. They display as small circles on your profile, so keep the design centered and simple.

Design tips:

• Use icons or single letters rather than detailed images
• Stick to your brand colors for a cohesive profile look
• The visible area is roughly the center 40% of the image

Image Quality Tips

Resolution

Always upload at the maximum resolution. Instagram compresses images, so starting with higher quality means better results after compression.

File Format

• JPEG for photographs (good compression, acceptable quality loss)
• PNG for graphics with text or sharp edges (lossless, larger file size)
• Upload at the highest quality your source allows

Color Space

Instagram converts all images to sRGB. If you edit in Adobe RGB or ProPhoto RGB, convert to sRGB before uploading to avoid washed-out colors.

Sharpening

Add slight sharpening before uploading. Instagram's compression softens images, so a small amount of pre-sharpening compensates.

Creating Instagram-Ready Images with MergeImages

Here is a practical workflow for creating Instagram content:

1. Prepare your photos — use the background remover to clean up product shots
2. Upscale if needed — the image upscaler can enhance low-res photos
3. Merge or collage — combine images into the right aspect ratio using the photo collage maker
4. Export — save as JPEG for photos or PNG for graphics

What About Video Dimensions?

Reels follow the same 1080 x 1920 (9:16) dimensions as stories. For feed videos, 1080 x 1080 (1:1) or 1080 x 1350 (4:5) work best. Always upload in the highest resolution available.
