Recently updated on January 16th, 2026 at 11:20 pm

A-frame signs are an excellent way for businesses to grab attention from people walking by their stores or along busy sidewalks. Their foldable, freestanding design makes it easy to set up, move around, and display wherever needed. They also come in various sizes, each offering its own level of visibility.

But what is the standard size for these sandwich boards? Let NextDayFlyers answer this as we take a closer look at two standard A-frame sizes that most businesses rely on for their everyday promotions.

24″ x 36″ vs. 18″ x 24″: The Two A-frame Standards

The 18″ x 24″ A-frame is a common choice for small spaces. Its compact design fits easily near entrances without blocking walkways, making it perfect for attracting attention from passersby.

The 24″ x 36″ A-frame works best for busier areas. The larger display stands out near storefronts, center islands, or bulletin boards, even serving as an affordable alternative to floor-standing banners.

Comparing these two sizes, both achieve their goals and offer advantages that business owners can maximize.

Standard A-frame Sign Design Tips and Uses

The standard A-frame sizes shine best with bold visuals and clear messages. Whether you choose the 18″ x 24″ or the 24″ x 36″, there are creative design ideas you can adapt to make them stand out more.

18″ x 24″ A-Frame Ideas

• Use bold headlines and your business logo for quick recognition but keep the layout clean and simple.

• When using directional arrows, make sure they point accurately to your store or event, so customers and eventgoers can easily find them.
• Consider printing multiple interchangeable graphics, each with their unique designs, so you can reuse the same A-frame holder for seasonal promotions and limited-time offers.

• Maximize the larger space by featuring big, eye-catching, and high-quality product photos, paired with strong headlines, and a clear call-to-action.
