How Big Is a 24×36 Frame? | Dimensions Explained

While a 24×36 frame is sized for a 24-inch by 36-inch print, the actual outer dimensions are often 1 to 3 inches larger.

When you shop for a 24×36 frame, the numbers refer to the artwork it’s designed to hold, not the frame’s outside edges. The frame’s border and lip add to the overall size. This distinction matters whether you’re hanging a poster above a sofa or measuring wall space for a gallery wall, since the real-world footprint can be noticeably bigger than the listed “24×36.”

What Does 24×36 Mean in Practice?

In standard framing terms, 24×36 means the frame is built to hold a print that is 24 inches wide by 36 inches tall, or 60.96 by 91.44 centimeters, matching a 2:3 aspect ratio common for posters and large photographic prints.

Because the frame’s lip overlaps the edge of the artwork, the visible portion of your print is usually smaller. Also, a 24×36 print typically needs the 24-inch side oriented horizontally—confirm which dimension is the height before ordering if hanging vertically.

Outside Dimensions Vary by Manufacturer

The outer dimensions of 24×36 frames differ by brand, so always check the product listing. Common examples from current listings:

• One listing gives overall measurements of 25.5 x 37.5 inches.

The “rabbet depth”—the groove where the print sits—determines how thick your artwork and backing can be. Most frames handle standard posters, but check that measurement if adding a thick backing board.

Does a 24×36 Print Need a Mat?

No, a 24×36 print fits a 24×36 frame directly, often framed without a mat in a “poster-style” presentation. If you want a mat, the frame’s inner opening must be smaller than the print. A 24×36 frame with a mat typically accommodates a smaller artwork, such as a 20×30 print, with a mat opening around 19.5 x 29.5 inches. The mat gives the art breathing room and a gallery-style look, but it reduces the visible area, so it’s not ideal if the artwork should dominate the wall.

How Will a 24×36 Frame Look on Your Wall?

Before hanging, measure the wall space, remembering the frame’s outer dimensions, not the print size, dictate its footprint. For a gallery wall, leave at least 2 to 3 inches between frames for a cohesive set. For a solo poster, center it at eye level, roughly 57 to 60 inches from the floor to the middle of the frame. The most common mistake is expecting the outer size to be exactly 24 by 36 inches—it’s always larger once border, lip, and hardware are included. Verify the specific listing’s outer dimensions before ordering, especially with tight space, and remember a mat reduces the artwork size the frame can hold.
