Reddit Free-Form Ad Character Limits
Free-Form ads support up to 4000 chars of rich body text but show ~200 chars on the feed before truncation. Title cap is 300 / 70 visible.
Reddit Free-Form Ads support the platform's full rich-text body — up to 4,000 characters of formatted content with images, links, lists, and Reddit-flavored markdown. The title cap is the same 300 characters (~70 visible) used by all Reddit ad formats. The body field is the differentiator: roughly 200 characters visible on the feed before "...more" truncation, with the full 4,000 available on tap.
Free-Form is Reddit's answer to "long-form ad copy works on Reddit" — the format performs especially well in research-heavy subreddits (r/personalfinance, r/cscareerquestions, r/buildapc, r/marketing) where users read thoroughly. Treat it as a mini-blog post inside an ad slot. The title still has to earn the click, but the body does the conversion work.
Free-Form titles: 70 chars visible
Body allows 4000 chars total — feed clamps at ~200 visible.

When Free-Form beats Promoted Post
Use Free-Form when (a) the audience is research-mode (career, finance, technical, hobby), (b) the offer benefits from detailed explanation, (c) the title alone cannot do the persuasion. Use Promoted Post for visual products and impulse-purchase categories.
