Instagram's New Portrait Grid: How to Resize Your Images for 2026

In January 2026, Instagram changed its profile grid from square (1:1) to portrait (4:5) format. This means your carefully curated square grid now displays as cropped portrait thumbnails.

Here's what changed and how to adapt.

What Changed

Before (2015-2025): Grid displayed as 1:1 squares (1080 x 1080 px) Now (2026): Grid displays as 4:5 portraits (1080 x 1350 px)

Old square images are center-cropped to fit the new portrait format, which means the top and bottom of vertical images show, but square images lose their side edges in the grid view.

The Impact on Existing Content

If you've been posting square images:

• They still display correctly when opened
• But in the grid view, they appear with letterboxing or cropping
• Your grid's visual consistency may be broken

If you've been posting 4:5 portrait images:

• Congratulations — your grid looks better than ever
• The new format showcases your existing portrait content properly

4. Resize to 1080 x 1350 px
5. Save as JPEG at quality 90+

Batch Resize (Pro)

If you need to resize your entire catalog:

1. Open the batch processor
2. Drop all your images
3. Set crop ratio to 4:5
4. Set resize to 1080 x 1350 px
5. Set output to JPEG, quality 92
6. Convert all and download

Creative Options for Square Images

Rather than just cropping square images to 4:5, consider these approaches:

Add vertical space: Place your square image in a 4:5 canvas with matching background color above and below. This preserves the full image.

Extend the background: For product shots on solid backgrounds, let the background color extend vertically to fill the 4:5 frame.

Reframe the composition: Use the extra vertical space to show more of the scene — crop wider instead of tighter.

Content Strategy for the New Grid

The portrait format changes what works visually:

• Vertical subjects shine — Full-body shots, tall products, vertical architecture
• Text-heavy posts — More vertical space for text overlays and infographics
• Before/after — Stack vertically instead of side by side
• Carousel covers — Design your first slide for 4:5 impact

Should You Re-Upload Old Posts?

Probably not. Re-uploading means losing your likes, comments, and engagement history. Instead:

• Accept that older posts will display slightly differently in the grid
• Focus on making new posts 4:5 native
• If your grid aesthetic matters significantly (brand accounts), consider re-posting key images with updated dimensions
