Framing guide
Frame Size:
For A4 prints (21 x 29.7 cm or 8.27 x 11.69 inches), I recommend using a frame that either fits the artwork exactly or includes a mat (border) for a more polished look.
With Mat: I suggest a frame that’s slightly larger, like an 11 x 14 inch frame with a mat opening for A4.
Without Mat: Use a standard A4 frame to fit the print exactly.
