Zillow Character Limit: Why There's No Single Answer

Searching for "Zillow character limit" turns up genuinely conflicting numbers — 2,000, 1,500, 1,000, even 500 — cited with equal confidence across different real estate industry sources. None of them are necessarily wrong; they're describing different things. Most listing descriptions on Zillow don't originate on Zillow at all — they're pulled from an MLS data feed, and different MLS boards enforce different limits on their own "public remarks" field before that text ever reaches Zillow.

Why the MLS, Not Zillow, Usually Sets the Real Limit

Bright MLS caps public remarks at 1,000 characters; CRMLS allows up to 1,500 — two different regional MLS systems with two different rules, and an agent's actual writing constraint depends entirely on which one their listing runs through. Since most agents write the description once in their MLS system and let it sync to Zillow, Realtor.com, and other portals automatically, the practical character budget is usually set upstream, by the MLS, well before Zillow enters the picture.

The One Number That's Actually Consistent

Regardless of which MLS fed the listing or how long the original description runs, Zillow truncates the visible text to roughly 250 characters on search-results cards before showing a "Read more" link — a detail confirmed consistently across multiple real estate marketing sources. That means the practical writing target for the part of a description guaranteed to be seen — before a buyer has to tap through — is around 250 characters, or about 40 words, no matter what the underlying MLS technically allows.

Front-loading the strongest, most specific detail into that first 250-character window matters more on Zillow specifically than on a platform with a single unified limit, precisely because the technical ceiling varies by MLS while the visible window doesn't. A description that reads perfectly across its full 1,000 or 1,500 characters can still fail on Zillow if the first 250 lead with the address instead of the one detail that actually differentiates the listing.

A Historical Wrinkle: The "What I Love About This Home" Section

Zillow previously offered homeowners a supplementary "What I Love About This Home" text section that functioned as a workaround for the tighter MLS description limits some agents faced — but that feature has since been removed, and any listing later claimed by an agent with an MLS subscription loses that supplementary write-up entirely. This is worth knowing mainly as context: some older guidance referencing that section reflects a feature that no longer exists on the platform.

Data on What Length Actually Performs

Zillow's own builder-focused guidance reports that plan descriptions of 200 or more characters see a 7% higher conversion rate than shorter ones, and spec descriptions of 350 or more characters see a 9% lift — concrete, if narrow, data points suggesting more detail generally helps within these ranges, at least for new-construction listings specifically. This doesn't resolve the broader "what's the real limit" confusion, but it does suggest erring toward more complete descriptions rather than terse ones, within whatever ceiling the source MLS allows.

What This Means for Writing a Description

Since the technical ceiling depends on an MLS board most writers don't control directly, the more reliable approach is writing toward the one number that's consistent everywhere — the roughly 250-character visible window — while treating the fuller MLS limit as room for supporting detail a genuinely interested buyer will scroll to read. Checking a draft's length against both figures, rather than assuming a single universal Zillow number exists, avoids both an abruptly truncated opening line and an underused MLS character budget.

---

The conflicting numbers attached to "Zillow's character limit" aren't a case of bad information — they're describing different layers of a system where the MLS, not Zillow, usually sets the technical ceiling. The one figure worth building a description around regardless of which MLS is involved is Zillow's own consistent 250-character truncation point, since that's the portion every buyer actually sees before deciding whether to read further.
