A 25×17 frame is a rectangular frame with a 25-inch by 17-inch opening, sized for artwork or media that measures 25 by 17 inches.
Whether you are framing a poster, print, or piece of art, knowing the actual size of a 25×17 frame matters more than the label. This size is not square, and the way a seller writes the numbers can change how you think about the frame’s orientation. The key to a proper fit lies in understanding what the listed measurement actually refers to.
The Meaning of a 25×17 Frame Size
A 25×17 frame designation describes a rectangular frame with one side measuring 25 inches and the other 17 inches. It is intended for media that is 25 inches by 17 inches. This is not a common square format, so it is used for specific poster sizes or custom artwork.
One retailer explicitly describes their product as fitting media that measures 25×17 inches, confirming the size refers to the intended artwork dimensions. When you see this notation, it typically means the frame’s inside opening is designed to hold a 25-inch by 17-inch piece.
The orientation of the frame depends entirely on how you mount it. A frame with a 25-inch horizontal side is landscape; rotate it 90 degrees and the same opening becomes 17 wide and 25 tall, which is portrait.
Orientation and Notation Confusion
Retailers often swap the order of the numbers to match how the frame is displayed. The same opening might be listed as 17×25 to signal a portrait orientation, even though the physical frame opening is identical. The numbers describe the same rectangle; only the arrangement changes.
This is one of the most common sources of confusion when buying a frame. A listing that says 25×17 might show a product photo in landscape, while another seller lists the same size as 17×25 for a portrait hanging. Before you order, determine whether you need the 25-inch side to be the width or the height in your space.
Another point worth checking is whether the size refers to the frame opening or the overall outside dimensions. One product listing for a “25×17” frame shows a larger outer measurement of 27.25 x 19.25 inches. This difference is the frame’s border, which adds roughly an inch on each side. Knowing which measurement you are looking at prevents ordering a frame that is too large for your wall space.
How to Measure for a 25×17 Frame
The most reliable way to check fit is to measure the frame opening itself, not the full frame. Adobe Express advises flipping an existing frame over and measuring the rebate—the inside lip where the artwork sits—rather than measuring the complete frame from edge to edge. This gives you the true visible area.
If you already own the artwork, measure the piece you intend to frame. The frame opening must match those dimensions closely. If you are adding a mat, the calculation changes. Frame It Easy notes that when matting is included, the inside frame dimensions equal the art plus matting. A mat border reduces the visible area, so the frame opening must be larger than the artwork itself to accommodate the mat.
Follow these steps to confirm a frame will work:
- Measure the width and height of your artwork or print.
- If using a mat, add the mat border width to each side to find the required frame opening.
- For a frame you already have, measure the rebate, not the outer edge.
- Note whether your measurement matches the width × height order in the product listing.
Frameley recommends recording dimensions as width × height × depth and separately measuring outside dimensions for placement planning. The depth matters for thicker canvases or artwork with mounting hardware on the back.
The Difference Between Frame Opening and Artwork Size
Knowing whether a frame size refers to the opening or the outer frame changes what you buy. A frame listed as 25×17 with an outer size of 27.25 x 19.25 inches has a border that occupies real wall space. If you are hanging the frame in a tight spot, the outer measurement is what matters for clearance.
The opening, however, determines what fits inside. Measuring the full frame instead of the rebate is a common mistake that leads to buying a frame too small for the artwork. The visible area of the artwork is the opening size, not the total frame footprint.

Finally, remember that the notation order is a matter of seller preference. The same physical frame may appear as 25×17 on one site and 17×25 on another. Confirm the orientation you need before purchasing, and always verify whether the number refers to the opening or the overall dimensions.
For quick reference, here is the distinction between the two key measurements:
| Measurement | What It Tells You | Best Used For |
|---|---|---|
| Frame opening (25×17) | The visible area where artwork sits | Checking if art or media fits |
| Outside dimensions (27.25 x 19.25) | The full frame including the border | Wall placement and clearance planning |
