Real Estate Yard Signs: Sizes, Setup, and What Actually Gets Calls

A yard sign is the cheapest lead source in real estate that still works. It sits on a lawn 24 hours a day for the length of a listing, it is seen by every neighbor and every passing car, and the people who call from a sign are already standing in the neighborhood they want to buy in.

The catch is that most agents order signs the way they order business cards — once, without thinking about it — and end up with the wrong size, single-sided, or a phone number nobody can read at 30 miles an hour. This is what to get right.

Sizes, and when to use each

Real estate uses a small set of sizes, and mixing them on purpose is part of a good sign system.

18x24 — the listing sign. This is the default and it is the size an H-stake is built for. It is large enough to read from the street and small enough to store a dozen in a car trunk. Unless you have a specific reason to go bigger, every listing gets an 18x24.

6x24 — riders. The narrow strips that clip above or below the main sign: Sold, Open House, Under Contract, Price Reduced, Coming Soon. Riders are how one sign does five jobs over the life of a listing. Order a set with every main sign — they are cheap and they are the difference between a sign that looks current and one that looks abandoned.

24x36 — land, large listings, and directionals. When a property is set back from the road, on acreage, or on a fast road, 18x24 is too small to read in time. 24x36 also works as an open-house directional at a busy intersection where you are competing with three other agents’ signs.

Single vs. double-sided

Print both sides. A listing sign is almost never seen from only one direction — a corner lot, a through street, a cul-de-sac with traffic looping past all show the sign from two angles, and a blank white back on any of them is an impression you paid for and threw away.

The back of a yard sign is free advertising you already own. Leaving it blank is the most common mistake in real estate signage.

Double-sided printing (called 4/4) is a small per-sign add. The only time single-sided (4/0) makes sense is a sign mounted flat against a building or fence where the back is physically not visible.

4mm or 6mm coroplast

Coroplast is corrugated plastic — the fluted material real estate and campaign signs are printed on. It comes in two weights that matter.

4mm is the standard. It is rigid enough to stand straight on an H-stake through a normal listing, it is fully weatherproof, and it is the lighter, lower-cost choice. For an agent whose signs go up when a listing goes live and come down at closing, 4mm is the right call.

6mm is about 50% thicker and noticeably stiffer. It resists bowing in wind, it survives being staked and pulled week after week, and it stores flat instead of taking a permanent curl. It is worth the upgrade in three cases: you reuse the same signs across many listings, you run 24x36 or larger where the extra rigidity keeps a big sign from flexing, or you are a team that pulls and re-places directional signs every weekend for open houses.

You can order both — 4mm for your standard listing signs and 6mm for the directionals and riders that get handled constantly.

Grommets

Grommets are reinforced holes punched into the sign for hanging or zip-tying. For standard H-stake mounting you do not need them. Add top two corners if you hang signs on a fence or a post, and all four corners for a sign in an exposed, windy spot where you want to zip-tie every edge down. When in doubt, skip them — a stake-mounted sign does not use them.

How many to order

Order enough to have a sign on every active listing at the same time, plus a buffer. Signs get damaged, stolen, and sometimes left at a property for weeks after closing before anyone retrieves them.

A rough baseline:

Situation	Main signs to keep on hand
Solo agent, 4–8 listings	10–15, plus a set of riders
Busy agent or small team, 10–20 listings	25–40, plus directional 24x36s
Team farming a neighborhood	50+, with open-house directionals always stocked

Riders are ordered in sets — a Sold, Open House, Under Contract, Price Reduced, and Coming Soon for every few main signs, since a listing cycles through several over its life.

The design that gets calls

A yard sign is read from a moving car, which gives you about two seconds. Everything about the design follows from that.

• Phone number is the largest element. Larger than your name, larger than the brokerage logo. If someone can read one thing on the sign at speed, it should be the number to call.
• Your name or team name second. A person, not just a company. People call agents they can picture.
• Status comes from the rider, not the main sign. Keep the main sign evergreen so it works for the whole listing; let the rider carry Open House or Sold.
• Brokerage branding is required but small. Most brokerages have brand standards for signs — follow them, but keep the logo from competing with the phone number.
• High contrast, few colors. Dark text on a light ground, or the reverse. Two or three colors total. A busy sign reads as noise from the street.

Skip the headshot on the sign itself unless it is small and off to one side. It rarely survives the two-second read, and it dates the sign the moment you change your photo.

Where signs fit with the rest of a farm

Yard signs and postcards do different halves of the same job. The sign captures the person already in the neighborhood; the postcard reaches the homeowner who has not thought about selling yet. Run both to the same farm area and the sign makes the postcard familiar — “that is the agent whose sign was on the corner” — which is exactly the recognition a farm campaign is built on. More on the mailing side of that is in our guide to postcard marketing for real estate, and the full print-and-mail setup for agents is on the real estate page.

When you are ready to order, the yard signs page has every size, both weights, and file templates so the phone number lands where it should.
