What is an A-Frame sign?

An A-frame sign is a freestanding, portable sign with two panels hinged at the top so it stands in the shape of the letter A. It is also called a sandwich board or a sidewalk sign. Businesses set one out during open hours to catch foot and street traffic, then fold it flat to store or move. Because the frame is reusable and the graphics are changeable, an A-frame sign is one of the most flexible ways to advertise right at the curb. The team at Signarama  builds them for retail, restaurants, real estate, and events. 

Why it is called an A-frame 

The name comes from the shape. Two panels join at the top and angle outward at the base, forming a triangle that looks like a capital A from the side. The same sign goes by a few other names depending on the industry and region. 

• Sandwich board, because a person or message sits between two panels. 

• Sidewalk sign, named for where it most often stands. 

• Sandwich sign or curb sign, regional terms for the same A-shaped format. 

How an A-frame sign works 

An A-frame stands on its own without a wall, post, or stake. The hinge at the top lets it open for display and fold flat for storage, and most models show a message on both faces so they work for traffic moving in either direction. That portability is the whole point: the sign goes out when you open and comes in when you close. 

What A-frame signs are made of 

The frame and the graphic are usually separate, which is what makes the format so durable. Frames come in plastic, steel, or aluminum, and the message is carried by a changeable insert or a printed panel. This split lets the sign last for years while the message updates as needed. 

• Plastic or poly frames, lightweight and economical for indoor or light outdoor use. 

• Steel and aluminum frames, heavier and weather-ready for full-time outdoor placement. 

• Changeable inserts, posters or writable panels swapped without replacing the frame. 

Common uses for A-frame signs 

A-frames show up anywhere a business needs to speak to people walking or driving by. They are quick to deploy, easy to update, and inexpensive enough to use every day. A few of the most common settings are below. 

• Retail storefronts, promoting sales, hours, or featured products at the entrance. 

• Restaurants and cafes, listing daily specials and menus on a writable panel. 

• Real estate open houses, directing buyers from the main road to the property. 

• Events and directional needs, guiding foot traffic to entrances, registration, or parking. 

Benefits of A-frame signs 

The format earns its popularity by being affordable, reusable, and easy to change. One frame from Signarama  can carry a new message every day, which makes it one of the lowest-cost ways to keep a fresh offer in front of passersby. 

Choosing the right A-frame sign 

Once the format makes sense, the next steps are size and budget. The guide on A-frame sign sizes covers the standard dimensions, and how much an A-frame sign costs explains what drives the price. When you are ready, Signarama  can recommend a frame and print the graphics so the sign is ready to set out.
