Facebook Text Overlay Checker

Does Facebook Still Have a Text Overlay Rule?

Facebook officially removed the 20% text rule in September 2020. Before that, ads with more than 20% text overlay were rejected outright or given dramatically reduced delivery. Facebook even provided an official Text Overlay Tool that used a 5×5 grid to check compliance.

However, the removal of the rule does not mean text no longer matters. Facebook's ad delivery algorithm still evaluates image quality, and text-heavy images are consistently deprioritized. Advertisers running A/B tests regularly report that cleaner images with less text receive more impressions, lower CPMs, and better engagement rates.

In practice, treating the 20% guideline as a best practice rather than a hard rule gives you the best results. This checker uses the same 5×5 grid method to help you evaluate your image before spending ad budget on it.

How to Check Text on Your Facebook Image

1. Upload your ad image — select or drag-and-drop the image you plan to use for your Facebook ad campaign.
2. View the 5×5 grid overlay — the tool displays your image with 25 equal grid cells overlaid, matching the method Facebook originally used to evaluate text coverage.
3. Mark cells containing text — click or tap each grid cell where text appears. Selected cells turn red and the text percentage updates in real time.
4. Review your result — the tool shows your text coverage percentage, a rating from OK to High, and specific recommendations. If your score is too high, reduce text using the free image editor or move copy into the ad headline and description fields instead.

Why Text Amount Matters for Facebook Ads

Even without a hard rule, the amount of text on your Facebook ad image has a measurable impact on campaign performance. Here is what advertisers consistently observe:

• Lower reach — Facebook's algorithm deprioritizes text-heavy images in the ad auction, meaning your ad is shown to fewer people for the same budget
• Higher cost per result — reduced delivery efficiency drives up your CPC, CPM, and cost per conversion
• Reduced engagement — users scroll past cluttered, text-heavy images faster than clean visuals with a clear focal point
• Lower relevance score — Facebook's ad quality metrics penalize images that users do not engage with, creating a negative feedback loop
• Wasted ad spend — paying for impressions on an image that the algorithm is actively suppressing means you get less value from every dollar spent

Checking text coverage takes seconds. Use this tool before launching, and preview your ad with the ad image preview to see the full layout. For sizing, use the Facebook image size checker.

How Much Text Is Too Much?

While there is no official cutoff anymore, years of advertiser data and the legacy of Facebook's own guidelines point to clear thresholds:

Examples of good images: product photos with no overlay text, lifestyle images with a small logo, clean graphics with a single short headline. These images let Facebook's ad system work in your favor.

Examples of problematic images: flyers with paragraphs of text, screenshots of articles, images covered in prices and bullet points, heavily branded graphics with multiple text blocks. These may still run, but at a significant performance disadvantage.

How to Reduce Text on Your Ad Images

If your image scores above 20%, here are practical ways to bring the text coverage down without losing your message:

• Move text to the headline and description fields — Facebook's ad format gives you dedicated text fields above and below the image. Put your offer details, CTAs, and supporting copy there instead of on the image itself
• Simplify your message — reduce text to a single short headline or tagline. One powerful statement is more effective than a paragraph
• Shrink text size — making text smaller can move it from occupying multiple grid cells to just one or two, dramatically lowering your percentage
• Use the text generator tool — add clean, well-positioned text to your images without overcrowding the design
• Focus on visual storytelling — let the image do the talking. A compelling photo of your product or result speaks louder than text overlay
• Create multiple versions — test a text-light version against a text-heavy version. Let the data confirm which performs better for your audience

Best Practices for Facebook Ad Text

• Keep text overlay below 20% of the image area for maximum ad delivery potential
• Use high contrast between text and background so it remains readable at small sizes without needing to be large
• Test multiple creative versions — run at least one clean image against one with text to compare performance
• Place text strategically in one area rather than scattered across the entire image
• Avoid all-caps text, which takes up more visual space and reads as aggressive
• Do not include text that duplicates your headline or description fields — it wastes image space
• Use this checker before every campaign launch to catch text-heavy images before they waste budget
• If your brand requires text-heavy images, increase your budget to compensate for reduced delivery efficiency

For a complete pre-launch check, combine this tool with the Facebook image size checker to verify dimensions and the Facebook post preview tool to see exactly how your ad will appear in the feed.
