MLS Public Remarks Character Limits: Board-by-Board Guide

BrightMLS gives you 2,000 characters for public remarks. CRMLS gives you 1,000. NWMLS gives you 1,000. That two-to-one difference means the description that flows beautifully on a Mid-Atlantic listing needs to be tightened significantly when the same agent submits a relocation property in Seattle or Southern California. Knowing your board's exact limit before you write — not after you paste and get the error — saves time and prevents truncated copy from going live.

This guide covers character limits for major MLS boards across the US, what counts toward the limit, and how to write tight copy that still converts buyers within any constraint. For a broader look at structuring your remarks effectively, see our complete guide to MLS descriptions.

Why MLS Character Limits Vary So Much

Every MLS board sets its own technical specifications, and public remarks limits have never been standardized across the industry. Some boards adopted higher limits when they updated their software platforms; others have kept conservative limits to maintain consistent display across IDX feeds, mobile apps, and print-formatted reports.

The variation also reflects different market philosophies. Boards serving dense metro markets with high search volume — like BrightMLS covering the DC-to-Philadelphia corridor — tend to allow longer remarks because agents compete heavily on description quality. Regional boards serving lower-volume markets often kept shorter limits from earlier platform generations and never had enough agent pressure to push for an increase.

What counts toward the character limit also varies. Most boards count every character including spaces, punctuation, and line breaks. A few count only visible characters excluding whitespace. Some boards have separate fields for agent remarks (visible only to other agents) versus public remarks (visible on Zillow, Realtor.com, and consumer IDX sites), each with its own limit. Always check whether you're filling the public remarks field or the agent-only remarks field — the character limits are almost never the same.

MLS boards update their limits when they upgrade software, so the figures below are current as of early 2026. Verify with your specific board before submitting a listing, particularly if you haven't checked recently.

Character Limits for Major MLS Boards

Here are the public remarks character limits for the largest MLS boards in the US. These are approximate and subject to change — confirm with your board's help center or listing input form.

BrightMLS (DC, Maryland, Virginia, Delaware, Pennsylvania, New Jersey): 2,000 characters. One of the most generous limits in the country, giving agents room for a full narrative description. Agents routinely use all 2,000 characters on luxury and unique properties.

CRMLS (Southern California — Los Angeles, Orange County, Riverside, San Bernardino, San Diego): 1,000 characters. The largest MLS by membership in the US. At 1,000 characters, every word must earn its place — lead with what is unique and let structured data fields carry the basics. For a detailed breakdown, see the CRMLS public remarks character limit guide.

NWMLS (Western Washington state — Seattle metro, Puget Sound region): 1,000 characters for public remarks. While more generous than some agents expect, 1,000 characters still requires tight, deliberate writing — especially since Zillow truncates to roughly 250 characters on mobile before showing a "Read More" prompt. For a detailed breakdown, see the NWMLS public remarks character limit guide.

Canopy MLS (Greater Charlotte, western North Carolina): 1,500 characters. Standard mid-range limit with enough room for a narrative description that covers the property's key selling points.

NTREIS (North Texas — Dallas-Fort Worth metro): Approximately 1,000 characters. A middle-ground limit that rewards concise writing. DFW agents typically prioritize the strongest 2–3 features and a clear buyer call to action.

Stellar MLS (Florida — Orlando, Tampa, Central Florida): 2,000 characters. Florida's largest MLS matches BrightMLS for generosity, which gives agents room to lean into lifestyle copy about outdoor spaces, community amenities, and proximity to attractions.

FMLS (Greater Atlanta — First Multiple Listing Service): 1,500 characters. A generous limit that gives agents room for full narrative descriptions with strong openings, key features, and a call to action.

HAR (Houston Association of Realtors): 1,500 characters. HAR also maintains a separate private remarks field for agent-to-agent notes.

ARMLS (Arizona Regional — Greater Phoenix): 1,500 characters. One of the fastest-growing MLS boards by transaction volume, ARMLS applies a standard limit that works well for Phoenix's mix of single-family, condo, and luxury inventory.

BAREIS (Bay Area, Northern California — Marin, Napa, Sonoma, Solano): Approximately 1,000 characters. The Bay Area's premium market makes every character count — agents at this limit tend to lead with the property's most differentiated feature rather than a general description.

GAMLS (Georgia MLS — Greater Atlanta and statewide): 2,000 characters. GAMLS and FMLS both cover greater Atlanta but maintain separate systems with different limits.

SABOR (San Antonio Board of Realtors): 1,500 characters. Standard limit consistent with most Texas-area boards.

How to Write Tight Copy for Short-Limit Boards

When you're writing for a 1,000-character board like CRMLS or NWMLS, a different set of rules applies than when you have 2,000 characters to fill. The mindset shift: don't try to compress a long description. Write a short one from scratch.

Lead with the single strongest feature. At 500 characters, you cannot afford a warm-up sentence. "Vaulted ceilings and mountain views on a quiet cul-de-sac in Issaquah" tells buyers more in 70 characters than two sentences of general praise.

Use specifics, not adjectives. "Spacious kitchen" uses 16 characters and says almost nothing. "Kitchen with quartz island, gas range, and room for a 10-person table" uses 68 characters and creates a clear picture. Specifics convert; adjectives fill space.

Cut connective tissue. Phrases like "this home features," "you'll love," and "don't miss this opportunity" are noise. Every clause should carry information a buyer can act on. These are among the most common MLS description mistakes that waste precious characters.

Reserve a sentence for the call to action. Even at 500 characters, one sentence pointing buyers toward a showing or open house improves conversion. "Showings start Friday — schedule via ShowingTime" takes 50 characters and earns its keep.

For boards with 1,500–2,000 characters, the strategy flips. Now you have room to tell a story: the morning light in the primary suite, the walk to the coffee shop, the way the backyard works for a family with kids. Use that space intentionally, not as an excuse to pad with filler phrases. For guidance on finding the right length for your market, see how long should an MLS description be.

Tools That Help You Hit the Limit

Counting characters manually is tedious and error-prone. A few approaches help:

Use a character counter before you paste. wordcounter.net and similar free tools give you a live character count including spaces. Paste your draft there before transferring to your MLS input form to avoid the frustrating truncation error on submission.

Write in a text editor with a character limit plugin. VS Code and many other editors support word count extensions that display character counts in the status bar. If you write listing copy regularly, this setup saves hours per month.

AI-assisted generation with limit awareness. Tools like ListingKit let you specify a target character range and generate MLS descriptions optimized for your board's limit. Rather than writing long and then cutting, you get a draft already calibrated to 500, 1,000, or 2,000 characters. This is particularly useful for high-volume agents who list across multiple markets with different board limits.

Template your structure. If you consistently list in a 1,000-character board like CRMLS or NWMLS, build a mental template with three zones: a hook (first 200 characters for the standout feature), a body (next 600 characters for key upgrades, rooms, and location context), and a close (final 200 characters for lifestyle framing and call to action). Templates remove the blank-page problem and ensure you don't discover you're over the limit after writing a full draft.

Frequently Asked Questions

Does the MLS character limit include spaces and punctuation?

In most MLS systems, yes — spaces, commas, periods, and other punctuation all count toward the character limit. A few older platforms count only alphanumeric characters, but this is increasingly rare. When in doubt, assume spaces count and write accordingly. You can verify by submitting a test entry or checking your board's listing input manual, which most boards publish online.

What happens if I exceed the MLS character limit?

Most modern MLS input forms either prevent submission until you reduce the character count or silently truncate the description to the limit. Truncation is the more dangerous outcome — your listing can go live with a sentence cut off mid-thought, which looks unprofessional and confuses buyers. Check your MLS platform's behavior so you know whether you'll get a warning or a silent cut.

Can I use the same description across multiple MLS boards?

You can, but you may need separate versions for boards with significantly different limits. An agent listing in both CRMLS or NWMLS (1,000 characters) and BrightMLS (2,000 characters) effectively needs two different descriptions. A practical approach: write the long version first, then edit down to the short version by removing your lowest-priority sentences first. This ensures the short version keeps your strongest material. For real examples of descriptions at different lengths, browse our MLS listing description examples.

How often do MLS boards update their character limits?

Most boards update limits when they upgrade their listing management software, which typically happens every few years. Some boards have held the same limit for a decade; others have raised limits in recent years as they switched to modern platforms. The safest practice is to verify your board's current limit at the start of each year or whenever you haven't submitted a new listing in several months. Your board's help center or member portal will have the current specifications.
