What Is Facebook Post Size?

Why is size so important?
- Correct sizes ensure your content displays clearly on all devices

Why Facebook Post Size Matters for Performance
Visual clarity = viewer retention
A post with the right dimensions ensures clean, readable, and eye-catching content. No cropped words. No pixelated images. No lost impact.
Proper sizing improves ad quality score
For advertisers, Facebook uses visual quality as a signal for relevance score—which impacts cost per click and reach.
Mobile-first design requires optimized sizes
Over 95% of Facebook usage happens on mobile. Poor sizing = poor UX.
Real-Life Scenario: How a Nonprofit Increased Engagement by 3x
A nonprofit organization running educational campaigns noticed low engagement on their posts. After resizing their images using the correct Facebook post size for both feed and story, they saw:
- 3x higher post shares
- 2x improvement in link clicks
- 40% lower cost per result on ads
Sometimes, it’s not about changing your message—it’s about fitting the frame.
Pro Design Tips for Facebook Post Dimensions
1. Use templates
Design in tools like Canva or Adobe Express that offer pre-sized templates for Facebook formats.
2. Leave space for overlays
Facebook’s UI elements (like buttons, profile icons, or swipe bars) can cover your text. Keep text in safe zones.
3. Test on mobile
Always preview your design on a phone before posting or launching ads.
4. Keep it clean
Don’t cram. White space improves readability, especially on vertical formats.
Common Mistakes to Avoid
- Uploading low-res images (minimum: 72 DPI recommended)
- Ignoring aspect ratios, leading to awkward crops
- Using too much text in story visuals (keep it minimal and punchy)
- Forgetting mobile formatting—especially in carousel or video content
Final Thoughts: Design That Works Is Design That Fits
In the race for attention, design details are the tie-breaker. Your content might have the message, but without the right Facebook post size, it may never get its moment to shine.
Remember: people don’t just scroll past bad designs—they ignore them entirely.
Master your dimensions. Respect the platform’s rules. And above all, let your content breathe in the right space.
