Quick answer: Use a 1440×1440 or 1440×1800 image (JPG or PNG), write primary text under 150 characters, cap your headline at 27 characters, and publish through Ads Manager with Facebook Feed selected as a manual placement.

Facebook feed ads appear right inside the news feed, between posts from friends and Pages. Getting the specs and copy right is the difference between an ad that blends in and one that drives clicks. This guide walks you through every step.
What is a Facebook Feed Ad?
Where it appears on Facebook
Facebook feed ads run in the main news feed on mobile and desktop. They appear between organic posts as users scroll. Per Meta's Ads Guide, the feed placement supports image, video, and carousel formats. Image ads are the fastest format to build and test.
Why feed ads are effective for businesses
The feed is where attention lives. Over 10 million advertisers run Meta ads because the feed combines high-intent scrolling with precise audience targeting. Square and vertical images take up more screen real estate than landscape formats. More visibility without extra spend.
Step 1: Plan Your Creative and Copy
Define your objective (awareness, traffic, conversions, etc.)
Pick your objective before you open Ads Manager. Meta's campaign structure starts here. Awareness builds brand recognition. Traffic sends users to a URL. Conversions drive purchases or sign-ups. Your objective controls which bidding strategies and optimization signals Meta uses.
Choose your image format (square 1:1 or vertical 4:5)
Square (1:1) works well on both desktop and mobile. Vertical (4:5) fills more of the mobile screen. Per Meta's Business Help Center guidance on aspect ratios across placements, both formats are recommended for Facebook Feed. Pick one before you start designing.
Step 2: Create or Prepare Your Image
Image size specifications (1440×1440 or 1440×1800)
Per Meta's Ads Guide, the recommended resolutions are:
- Square (1:1): 1440×1440 pixels (minimum 600×600)
- Vertical (4:5): 1440×1800 pixels (minimum 600×750)
Minimum image width is 600 pixels. Meta applies a 3% aspect ratio tolerance across devices.
File type and technical requirements
Use JPG or PNG. Maximum file size is 30MB. Meta no longer enforces a text-on-image percentage limit. Text overlays are allowed without penalty, though excessive text can still hurt engagement.
Design best practices for feed ads
Lead with a clear focal point. Use contrast to make your product stand out. Keep any text on the image concise. Busy backgrounds pull attention away from your product. One strong visual beats a cluttered composite every time.
Step 3: Write Your Ad Copy
Primary text guidelines (50-150 characters)
Per the Meta Business Help Center, primary text should be 50-150 characters. Front-load your key message in the first 80 characters. Many users see truncated text before tapping "See more." Get to the point fast.
Headline best practices (27 characters)
Your headline is capped at 27 characters. Make every character count. A sharp benefit or offer works best. "50% off today only" beats "Check out our latest deals" every time.
Call-to-action tips
Match your CTA button to your objective. "Shop Now" for conversions. "Learn More" for awareness or traffic. Meta's creative best practices recommend using a question or bold statement in primary text to capture attention in feed. Lead with the offer, not the brand name.
Step 4: Launch Your Ad in Ads Manager
Create a campaign and select your objective
Open Ads Manager at business.facebook.com. Click "Create" and choose your campaign objective. Name your campaign clearly so you can track performance easily later.
Choose manual placements and select Facebook Feed
At the ad set level, switch from Advantage+ Placements to manual placements. Select "Facebook Feed" only. This keeps your budget focused on the placement you have optimized for, instead of spreading it thin.
Upload image and copy
At the ad level, upload your image. Add primary text, headline, and choose your CTA button. Preview on mobile before publishing. The mobile feed preview is the most important check before you go live.
Set audience and budget
Define your audience by location, age, interests, or custom audiences. Set a daily or lifetime budget. Start with a daily budget to control spend while you test. New campaigns need enough budget to gather data before Meta's algorithm can optimize delivery.
Optimize Your Facebook Feed Ads
A/B test different images and copy
Run two creatives at once. Change one variable per test. Same copy, different image. Or same image, different headline. The Coinis Revise Variate feature generates multiple image variations from a single creative in one click. No redesign needed.
Monitor performance with the Advertise page
Track CTR, CPC, and ROAS on the Coinis Advertise page. Spot underperformers fast. Pause what isn't working. Scale what is. Consistent monitoring beats weekly check-ins.
Use Coinis Revise to refresh underperforming creatives
Stale creatives cause ad fatigue. Use Revise to swap colors, update text directly on your image, or resize for new placements with Smart Resize. No design skills needed. Much faster than rebuilding a creative from scratch.
