Perfecting Your Instagram & Facebook in 2025

In 2025, social media success is about more than posting great content; it’s about optimizing visuals to look great everywhere they appear. 

Whether you're running a business account or managing client content, perfecting your Instagram and Facebook post sizing is essential for getting attention and driving engagement.

Poorly sized images can lead to awkward cropping, blurry videos, or even reduced reach if Meta’s algorithm flags low-quality content. 

This guide will walk you through the latest Instagram and Facebook sizing specs for 2025, plus practical tips to help you design with confidence.

Why Post Sizing Still Matters in 2025

With the rise of short-form video, high-resolution displays, and algorithmic feeds, proper sizing isn’t just aesthetic, it’s strategic. Here’s why it matters:

• Avoid Cropped Content: Incorrect dimensions can cause text or subjects to be cut off, reducing clarity.

• Boost Engagement: Well-formatted visuals perform better and keep users on your content longer.

• Improve Ad Performance: Meta rewards high-quality creatives with better delivery and lower cost-per-click.

• Build Brand Consistency: Uniform visuals create a more professional and trustworthy profile.

Instagram Post Sizes (2025 Update)

Instagram remains one of the most visual-first platforms, and getting your sizing right helps your posts stand out.

1. Instagram Feed Posts

• Square: 1080 x 1080 px

• Portrait (recommended): 1080 x 1350 px – Takes up more vertical space and grabs attention

• Landscape: 1080 x 566 px – Works well for wide-format content like travel or panoramic views

Tip: Portrait posts tend to perform better on mobile because they occupy more screen space.

2. Instagram Stories & Reels

• Size: 1080 x 1920 px (aspect ratio: 9:16)

• Safe Zone: Keep all text and logos inside the center 1080 x 1420 px area to avoid being cut off by UI elements

Pro Tip: Design with the top and bottom 250 pixels clear of essential info (Instagram overlays appear here).

3. Instagram Carousels

• Best Size: 1080 x 1350 px (portrait) for full-screen mobile effect

• Consistency is key: Use the same size across all slides to create a seamless swipe-through experience

4. Instagram Ads

• Feed Ad: 1080 x 1350 px or 1080 x 1080 px

• Story/Reel Ad: 1080 x 1920 px

• Aspect Ratio: Stick to 4:5 for feed ads and 9:16 for stories to maximize screen real estate

Meta Rule of Thumb: Keep text under 20% of the image to avoid reduced ad delivery.

Facebook Post Sizes (2025 Update)

Facebook continues to be a powerful platform for both organic and paid content, especially for older demographics and community engagement.

1. Image & Link Posts

• Square image: 1080 x 1080 px – Ideal for mobile visibility

• Link preview: 1200 x 630 px – Optimized for shared links and website promotions

• Landscape: 1200 x 900 px – Best for wide-format content

Note: Link preview images are automatically pulled from the website unless manually customized.

2. Facebook Stories

• Size: 1080 x 1920 px

• Safe Zone: Same as Instagram—avoid placing key visuals in the top and bottom 250 px

3. Facebook Video Posts

• Square: 1080 x 1080 px – Great for mobile feeds

• Vertical: 1080 x 1350 px – Ideal for high engagement

• Landscape: 1280 x 720 px – Better for wide scenes or desktop-first audiences

Reminder: Always upload videos in the highest resolution available to avoid compression.

4. Facebook Ads

• Feed Ad: 1080 x 1080 px (square) or 1200 x 628 px (landscape)

• Story Ad: 1080 x 1920 px

• Right Column Ad: 1200 x 1200 px (rarely used but still effective for some B2B campaigns)

File Format Tip: Use .PNG for high-quality images and .MP4 for videos.

Design Tips for Both Platforms

• Stay Within the Safe Zones: Always test your creatives in preview mode before posting to ensure nothing gets cut off.

• Use High-Resolution Files: Blurry or pixelated content hurts engagement and brand trust.

• Brand Consistency Matters: Stick with your color palette, font style, and logo placement across every post size.

• Optimize Thumbnails for Videos: Choose a clear and eye-catching frame that entices viewers to click.

• Mobile-First Always: Over 95% of Meta platform users access content via mobile. Design for vertical viewing.
