Facebook Feed Ad Sizes

Facebook Feed is the most flexible Meta placement. It accepts a wide range of aspect ratios and renders on both desktop and mobile.

Recommended resolution and aspect ratios

Per Meta's Ads Guide, Facebook Feed image ads support aspect ratios from 1.91:1 to 4:5. Portrait (4:5) takes up more screen real estate on mobile.

Recommended (1:1 square): 1440 × 1440 px
Recommended (4:5 portrait): 1440 × 1800 px
Supported range: 1.91:1 to 4:5
Meta allows a 3% tolerance on aspect ratios.

Minimum image specifications

Minimum (1:1): 600 × 600 px
Minimum (4:5): 600 × 750 px
File formats: JPG or PNG
Max file size: 30 MB

Text safe zones and file size limits

Meta recommends keeping primary text to 50–150 characters and headlines to 27 characters. These are recommendations, not hard caps. Long text gets truncated in the feed view. Short and punchy works better.

Facebook Stories Ad Sizes

Stories run full-screen vertical. There is no landscape option here.

Full-screen vertical format specs

Aspect ratio: 9:16
Recommended resolution: 1440 × 2560 px
File formats: JPG or PNG
Max file size: 30 MB

Safe zone for UI elements

Meta's Stories format overlays profile icons and CTA buttons on top of your creative. Keep key visuals and all text in the middle band.

Top ~14% (~250 px): Reserved. Keep clear.
Bottom ~20% (~340 px): CTA button area. Keep clear.
Everything between: Your safe zone.

Character limits for ad copy

Follow the same Meta recommendations: 50–150 characters for primary text, 27 characters for headlines. Short copy is especially important in Stories. Viewers tap through fast.

Facebook Reels and Video Ad Sizes

Facebook Reels ads run full-screen vertical, same as Stories. Per Meta's video ads documentation for Facebook Reels:

Vertical 9:16 ratio specifications

Aspect ratio: 9:16
Recommended resolution: 1080 × 1920 px
File formats: MP4, MOV

Safe zones and text placement

Facebook Reels overlays UI on the top and bottom of the frame. Place your logo and key messages in the center vertical third of the creative. Avoid the edges on all four sides.

File size and duration limits

Max video duration: 60 seconds
Max video file size: 4 GB

---

Right Column is a desktop-only placement. It appears in the sidebar on Facebook's desktop interface. The display area is small.

Square 1:1 format for desktop ads

Right Column ads render square. No portrait or landscape options.

Aspect ratio: 1:1

Minimum and recommended dimensions

Minimum: 254 × 133 px
Recommended: 1080 × 1080 px

Always upload at the recommended resolution. The minimum renders too small for text or detail to read clearly.

Text recommendations

Keep text minimal on Right Column creatives. The display size is small compared to Feed or Stories. Bold product shots and simple brand marks outperform text-heavy designs at this scale. Follow Meta's standard copy recommendations for headline and primary text.

---

Instagram Feed and Stories Ad Sizes

Instagram Feed favors portrait. Instagram Stories demand full-screen vertical. Different ratios, same 30 MB limit.

Instagram Feed vertical (4:5) specifications

Aspect ratio: 4:5 recommended
Recommended resolution: 1440 × 1800 px
Minimum width: 500 px
File formats: JPG or PNG
Max file size: 30 MB

Instagram Stories full-screen (9:16) format

Per the Facebook Business Help Center, Instagram Stories image ads use:

Aspect ratio: 9:16
Recommended resolution: 1080 × 1920 px
Minimum resolution: 600 × 1067 px
Max file size: 30 MB
Default display duration: 5 seconds for static images

Cross-platform safe zones

Facebook Stories and Instagram Stories share identical safe zones. Top ~14%, bottom ~20% are both off-limits for key creative elements. Design once. Apply to both placements.

---

Instagram Reels Ad Sizes

Instagram Reels has stricter safe zones than any other Meta placement. More UI elements compete for screen space along the edges and bottom.

Full-screen vertical 9:16 format

Per Meta's Ads Guide for Instagram Reels:

Aspect ratio: 9:16
File formats: JPG or PNG
Max file size: 30 MB

Safe zones for text and logos

Top ~14%: Keep clear of text and logos
Bottom ~35%: The largest restricted zone on any Meta placement. Keep clear.
Each side ~6%: Keep clear of text and logos

That leaves a tall, narrow safe zone in the center. Design your Instagram Reels creatives with this in mind from the start.

Recommended resolution

Recommended: 1440 × 2560 px

That is the highest recommended resolution Meta specifies for any image ad placement.

When to resize for different channels

One original image rarely fits every placement without cropping. Start with 4:5 for Feed. Export 9:16 for Stories and Reels. Keep 1:1 ready for Right Column and any square-format use. That is three exports per creative, minimum.

Coinis Revise handles this with Smart Resize. Upload once. Pick your placements. The right dimensions come out the other side automatically.

Frequently Asked Questions

What is the best image size for Facebook Feed ads?

Meta recommends 1440 × 1440 px for square (1:1) and 1440 × 1800 px for portrait (4:5) Facebook Feed image ads. Both accept JPG or PNG files up to 30 MB. The 4:5 portrait format takes up more screen space on mobile feeds.

Can I use the same image for Facebook Feed and Facebook Stories?

No. Facebook Feed uses a 4:5 or 1:1 aspect ratio. Facebook Stories require a 9:16 full-screen vertical format. Using the same file without resizing will result in cropping. You need separate exports for each placement.

What is the safe zone for Instagram Reels ads?

Instagram Reels has the most restricted safe zone of any Meta placement. Keep the top ~14%, bottom ~35%, and each side ~6% completely free of text and logos. Only the center vertical band is reliably visible to viewers.

What file formats do Facebook and Instagram ads accept?

All Meta image ad placements accept JPG and PNG formats. The maximum file size is 30 MB for image ads. Facebook Reels video ads accept MP4 and MOV files up to 4 GB.
