15x20 centimeters converts to about 5.9 x 7.9 inches, often rounded to 6 x 8 inches for framing. That means it’s much smaller than a 15x22 inch frame.

• Exact math: 1 cm ≈ 0.3937 in, so 15 cm ≈ 5.9 in and 20 cm ≈ 7.9 in.
• Framing options: For a snug fit, look for frames labeled 6x8 inches.
• Using a 15x22 frame: You can add a mat with a 6x8 opening and an outer size to fit 15x22. This creates a wide border around the photo.

Measurements can vary slightly by manufacturer, so checking the exact opening size can be helpful.

It depends on whether your 15x20 is in centimeters or inches.

• If it’s 15x20 cm: That’s roughly 6x8 inches. A 6x8 frame usually works, or use a larger frame with a mat cut to 6x8.
• If it’s 15x20 inches: Look for a frame labeled 15x20 inches for a close fit. If you prefer a border, choose a larger frame and use a mat with a 15x20 opening.
• Using 15x22 frames: A 15x22 frame can display a 15x20 inch print with a custom mat; expect extra margin on the longer sides.

Mat openings are typically cut slightly smaller to hold prints in place.

“15x20” can mean two different things, and the unit makes a big difference.

• 15x20 centimeters: About 6x8 inches. This is a common small photo size.
• 15x20 inches: A larger poster/print size used for wall art.

The aspect ratios differ too: 6x8 is 4:3, while 15x20 is 3:4. If you’re pairing a print with a frame (like 15x22), consider using a mat to bridge size and ratio differences. When in doubt, measure the actual print and review the frame’s listed opening dimensions to help you choose a comfortable fit.

22x28 inches is widely considered a common poster frame size in the U.S., often used for event posters and wall art. Pre-made frames at that size are typically easy to find across many retailers.

• Fit check: Match your artwork’s exact dimensions to the frame’s listed opening.
• Aspect ratio: 22x28 is a different ratio than 15x22, so a print designed for 22x28 won’t fit a 15x22 frame without a mat or resizing.
• Matting: If you prefer extra border, choose a larger frame and add a mat cut to 22x28.

Product specifications vary, so reviewing details before purchasing is a good step.

A 16x20 inch print is wider than a 15x22 frame’s 15-inch side, so it typically won’t fit without trimming or scaling. To preserve the full image, consider alternatives:

• Use a 16x20 frame: This accommodates the print without cutting.
• Go larger with a mat: Choose a bigger frame and add a mat with a 16x20 opening.
• Custom matting: If you’re set on 15x22, only a significantly cropped or reduced print could work with a custom mat, which may change the composition.

Reviewing frame opening sizes and your print’s exact measurements can help you avoid surprises.
