Creating a successful Facebook ad requires more than a great image or video.
The ad copy is what hooks your audience and drives conversions. Unlike organic posts, however, ad copy must follow Meta’s strict rules, character limits, and review policies.
This guide breaks down Facebook ad text limits, how formatting works, and smart practices for using emojis in Facebook ads without triggering a rejection.
📏 Facebook Ad Text Limits
A Facebook ad has three main copy elements. Each has a role and recommended length:
1. Primary Text
- Appears above your image or video.
- Official limit: 5,000 characters.
- Best practice: 50–150 characters.
- The first 125 characters are most important since everything beyond is hidden behind “See More.”
👉 Placement Tip: Keep your hook and benefit upfront.
2. Headline
- Appears below the creative in bold.
- Official limit: ~40 characters.
- Many placements truncate after 27 characters.
- Best practice: Aim for under 27 characters for safety.
👉 Placement Tip: Treat it like a mini-headline. Example: “Faster Shipping 🚚”
3. Description
- Appears under the headline (optional).
- Limit: ~30 characters.
- Often cut off on mobile.
- Best practice: Use it for secondary CTAs like “Free Trial Available.”
✍️ Bold and Formatting Rules
Unlike Facebook posts, Unicode bold text generators are not allowed in ads. Meta flags these as non-standard characters.
✅ Allowed formatting methods:
- Punctuation: “Limited time offer… act now!”
- Capitalization: “NEW DEAL” (use sparingly).
❌ Avoid:
- Unicode “fonts” (𝑭𝒂𝒏𝒄𝒚 𝑻𝒆𝒙𝒕).
- Replacing words with symbols.
😀 Using Emojis in Facebook Ads (Safely)
Emojis can boost engagement, but only if used strategically.
✅ Do:
- Break up lists → “Includes: 🚀 Fast delivery, 💰 Affordable prices, ✅ 24/7 support.”
- Convey tone → 🙂 friendly, 🔥 urgency, 🎉 celebration.
❌ Don’t:
- Overload → 🚀🔥💯😍😎🥳 in one line.
- Replace words → “Get 🔥 now” instead of “Get it now 🔥.”
- Use prohibited emojis → ⭐ is risky since it resembles ratings.
🛑 Avoiding Ad Review Rejection
Before submitting your ad, check for these common rejection triggers:
- Personal attributes → Wrong: “Are you struggling with debt?”
Correct: “Solutions for people managing debt.” - Unrealistic claims → Wrong: “Lose 50 pounds in 7 days.”
- Image text overload → Meta discourages text-heavy creatives.
✅ Best Practices Recap
- Keep primary text under 150 characters with the hook in the first 125.
- Use short, punchy headlines under 27 characters.
- Use emojis to enhance—not replace—your words.
- Avoid Unicode “bold text” tricks; rely on punctuation and capitalization.
- Double-check for policy compliance before submitting.
📌 FAQ
Q: Can I bold text in Facebook ads?
No. Bold/italic via Unicode will likely trigger rejection. Stick to caps and punctuation.
Q: How many emojis can I use in an ad?
Use 1–3 per line max. More looks spammy and risks rejection.
Q: Do Facebook ads have a character limit?
Technically, no- Facebook doesn’t enforce strict character limits. However, keeping your ad copy short is highly recommended to improve visibility and engagement.
Recommended lengths by section:
- Primary Text: Up to 125 characters for best display.
- Headline: Around 40 characters (some placements only show 27).
- Description (below link): About 30 characters.
- Image/Video Overlay: Keep text under 20% of the visual to avoid reduced reach.
Pro Tip: Write concise, compelling messages and test different versions to see what performs best. For full details, review Meta’s Ad Guidelines.
