Text Overlay Rules for Meta Ads: How Much Text Is Too Much

Treat text density as a design and comprehension question. Make the offer readable in the actual mobile placement, keep necessary terms visible and test the commercial outcome. Do not derive an auction surcharge or current policy from the percentage of pixels containing letters.

Separate current acceptance from inherited text-area rules

Check the current ad review and placement guidance for the actual creative. An old 20% image-text grid is not a dependable current delivery contract, and this guide does not establish a retirement date or automatic5–80% CPM penalties. Text can be relevant to what the ad communicates; moving a claim into primary copy does not make that claim irrelevant to review or effectiveness.

Three matched text versions at mobile scale

For a flat black/white text pair, the calculated WCAG contrast ratio is 21:1. W3C contrast guidance uses4.5:1 for normal text and 3:1 for large text with defined exceptions; it does not declare a universal 7:1 advertising threshold. Image-text size, antialiasing, overlays and a moving background still affect legibility. A contrast calculation is not a measured reader response.

• Preview the final crop with interface overlays on the selected placements. Measure the displayed scale, inspect the text/background pair and read it at normal phone distance.
• Ask representative readers what offer/terms they understood and record actual feedback when collected. Do not invent readability scores or infer comprehension from text area alone.
• If essential text fails, shorten or rearrange it while preserving truthful terms. A second line can be necessary; do not remove material information only to reduce coverage.

Choose by a budgeted business test

Predefine a supported controlled comparison with identical product, offer, audience eligibility and destination, a primary unique mature-order/contribution metric, required precision and cash cap. Keep raw impressions/clicks/session denominators so diagnostic ratios remain interpretable. If three arms exceed the available evidence, run a smaller question rather than inventing a55/25/20 winner distribution.

Prepare the approved text alternatives alongside a NovaStorm campaign draft, then have the user inspect the actual generated/exported image for spelling, truth, readability and covered terms. Text preparation is not a product promise of area scoring, auction optimization or automatic policy approval.
