Why 18x24 inches works best

18x24 inches is the sweet spot for visibility and ease of use. It’s noticeable but not bulky.
This size fits all typical hardware and meets most city sign rules. Coldwell Banker favors it for clean, consistent branding.

Material choices: Corrugated, PVC, or Aluminum

You can choose from:

• 4mil corrugated plastic: affordable and light, best for short-term or single-event signs.

• 3mil PVC: thicker and stronger, great for repeated use over time.

• 3mil aluminum: the toughest and weatherproof option, perfect for long-term outdoor signs.

Pick the material based on how long you’ll use the sign and local weather conditions.

Hardware options for your sign setup

If your sign goes in soft soil, stakes are simple and effective. Econo Stake 10x30 is good for light duty. Heavy Duty 10x30 stakes add more hold for rough ground. For hard surfaces like sidewalks, Wire A-Frames or A-Frames keep signs steady without needing ground insertion.

Are grommets necessary?

Grommets protect sign corners and keep signs secure when hanging or tied. Skip them if your sign fits snugly inside a frame. For windy or outdoor hanging setups, top, bottom, or both grommet options add strength.

Who benefits most from these signs?

Real estate agents, landlords, and property managers find these signs essential. They boost open house visibility and make it easy for visitors to find your listing.

Quick tips to finalize your sign order

Go with 18x24 inches for balance and compliance. Match material to your expected sign lifespan. Choose hardware depending on ground type. Add grommets if you’ll hang or expose the sign to wind.
