Quick answer

For a standard frame, choose a poster in a common size like 30x40 cm, 40x50 cm, or 50x70 cm. Measure your frame's inner opening and match it to the poster's dimensions—allow a small margin if the frame includes a mat.

Standard frame sizes vs. poster sizes

Most ready-made frames come in sizes like 21x30 cm, 30x40 cm, 40x50 cm, 50x70 cm, and 70x100 cm. These match common poster dimensions, but always check the frame's inner opening—some frames are designed for a mat that reduces the visible area.

If you already have a frame, measure the space where the poster will sit. For a frame with a mat, the opening is smaller than the frame's outer size. For a frame without a mat, the opening equals the glass size.

Trade-offs when sizing up or down

Choosing a poster slightly smaller than the frame opening lets you add a mat for a polished look. A poster that exactly matches the opening gives a clean, modern edge but leaves no room for error in alignment.

If your poster is larger than the frame, you can trim it, but this may cut off design elements. For abstract prints like the 'Fleeting' poster, trimming could change the composition. For geometric designs like '8.5.2 AVENUE', precise alignment is more forgiving.

How to match your poster to a standard frame

  • Measure your frame's inner opening: Use a ruler to measure the width and height of the space where the poster will sit. For frames with a mat, measure the mat's opening. Write down the exact numbers.
  • Choose a poster size that matches or is slightly smaller: If your frame opening is 40x50 cm, pick a 40x50 cm poster for a flush fit, or a 30x40 cm poster if you plan to add a mat. Most posters come in standard increments that align with common frame sizes. A poster that is 1-2 cm smaller than the opening works well with a mat.
  • Consider the poster's design: For prints with a clear border or geometric pattern, exact sizing matters more. For abstract or soft-edged designs, a small gap or trim is less noticeable. Always check the poster's composition before cutting. Abstract prints offer more flexibility in sizing.

Product facts to consider

  • Fleeting: Art print featuring soft, blurred contours and flowing soft beige shapes emerging against a dark brown surface. Its abstract, blurred edges mean minor size mismatches are less noticeable, making it a flexible choice for slightly oversized or matted frames.
