18x24 Open House #2 – Coldwell Banker Signs Explained

What buyers and agents want to know

What size open house sign should I pick?
Which material lasts longest?
What’s the right hardware for my yard?
Are grommets really necessary?

These are common questions from real estate pros and property owners. This guide answers them quickly and clearly.

Why 18x24 inches is the go-to size

18x24 inches strikes the perfect balance. It’s visible without being bulky or hard to carry.
This size fits standard hardware options and city regulations. Coldwell Banker relies on this size to keep listings uniform and professional.

Choosing the right material: Corrugated, PVC, or Aluminum?

4mil corrugated plastic is affordable and good for short-term use, like a weekend open house. 3mil PVC is thicker and tougher, suitable for repeated use over a few months. 3mil aluminum is the most durable and weatherproof — ideal for signs that need to last multiple seasons.

Pick corrugated if budget is tight. Go for PVC or aluminum if you want longevity and strength.

Which hardware fits your setup?

If your sign will be placed in soft soil, stakes work well. Econo Stakes 10x30 are lightweight and easy to use. Heavy Duty Stakes 10x30 provide extra stability in tougher ground. For hard surfaces like sidewalks, Wire A-Frames or A-Frames keep signs steady without needing to stick into the ground.

Do you need grommets?

Grommets protect your sign edges from tearing when you hang or tie the sign. Choose none if your sign stays inside a frame. For windy areas, top, bottom, or both grommets help keep your sign secure.

Who benefits most from these signs?

Real estate agents, FSBO sellers, and property managers all find these signs handy. They boost your listing’s visibility and guide traffic to your open house without confusion.

Final advice for picking your sign options

Stick with 18x24 inches. Match material to how long you’ll use the sign. Pick hardware based on ground type. Add grommets if you’ll hang or expose the sign to wind.
