Facebook & Instagram Post Sizes: The Complete Guide for 2026
Getting your Facebook post size and Instagram image dimensions right is the difference between content that looks professional and content that gets cropped, stretched, or pixelated. This guide covers every Facebook post size, Instagram post size, and video dimension you need for both platforms — feed posts, Stories, Reels, ads, profile pictures, and cover photos — updated for 2026.
Whether you’re looking up the correct Facebook image size for a feed post or trying to figure out Instagram post dimensions for a carousel, this is the only reference you need.
Facebook Post Sizes

For square posts in the feed, use 1080 × 1080 pixels (1:1 ratio). Square Facebook image post sizes take up more vertical space in the mobile feed, which can increase engagement.

Instagram Post Sizes and Dimensions
Instagram Feed Post Image Size
Instagram supports three aspect ratios in the feed:
| Format | Dimensions | Aspect Ratio | Best For |
|---|---|---|---|
| Square | 1080 × 1080 | 1:1 | Product shots, quotes, graphics |
| Portrait | 1080 × 1350 | 4:5 | Most engaging format, takes up more screen |
| Landscape | 1080 × 566 | 1.91:1 | Panoramic shots (least common) |
Best practice: Use 1080 × 1350 (4:5 portrait) for maximum feed real estate. Instagram’s feed is mobile-first, and taller images stop the scroll better than square or landscape.
Instagram Feed Post Video Dimensions
- Recommended resolution: 1080 × 1350 (4:5) or 1080 × 1080 (1:1)
- Maximum duration: 60 minutes
- Maximum file size: 3.6 GB
- Minimum resolution: 720p
- Format: MP4 or MOV
- Frame rate: 30 fps recommended
Instagram Carousel
- Same dimensions as feed posts — 1080 × 1080 or 1080 × 1350
- Up to 20 slides per carousel (increased from 10 in 2024)
- Mix of images and videos allowed
- All slides must use the same aspect ratio — the first slide sets the ratio for the entire carousel
Instagram Stories
- Recommended size: 1080 × 1920 pixels
- Aspect ratio: 9:16
- Image duration: 5 seconds
- Video duration: Up to 60 seconds
- Safe zone: Keep key content within the center area — approximately 100px from top and 250px from bottom to avoid overlap with username (top) and reply bar (bottom)
Instagram Reels
- Recommended size: 1080 × 1920 pixels
- Aspect ratio: 9:16
- Duration: 3 seconds to 15 minutes (extended from 90 seconds in 2025)
- Cover thumbnail: 1080 × 1920 (but displays as 1080 × 1350 in the grid)
- Format: MP4 or MOV
Reels cover tip: When choosing a cover photo, remember that it will be cropped to 4:5 in your profile grid. Center your key visual elements accordingly.

- Displays at: 110 × 110 on mobile, 180 × 180 on desktop

- Primary text: 125 characters recommended (up to 3 lines visible before “See More”)
- Headline: 27 characters recommended

Tips for Getting Facebook and Instagram Image Sizes Right
Design for mobile first. Over 90% of Facebook and Instagram usage is on mobile. Always preview how your content will look on a phone screen before publishing — what looks great on desktop may have the wrong Facebook photo size for mobile.
Use the 4:5 portrait ratio whenever possible. For both feed posts and ads, 1080 × 1350 takes up the most screen real estate in the mobile feed. This applies to both Facebook post dimensions and Instagram post dimensions. More screen real estate means more attention.
Account for cropping. Profile pictures get cropped to circles. Reels covers get cropped to 4:5 in the grid. Story content gets partially covered by UI elements. Always design with these crops in mind.
Export at 2x for retina displays. If possible, create images at double the display resolution (e.g., 2160 × 2700 for a 4:5 post). This ensures your content looks sharp on high-resolution phone screens.
Keep file sizes reasonable. While platforms accept large files (up to 30 MB for images, 4 GB for video), smaller files load faster. Aim for under 1 MB for images and under 500 MB for most videos.
