150 DPI is the usual floor for posters viewed from one to two metres away.
Will your image be big enough?
- A 12 MP phone photo (4,032 × 3,024) prints at up to 20.16 × 26.88 in at 150 DPI: enough for A5 (148 × 210 mm) without upscaling.
- A 1024 × 1024 AI image (1,024 × 1,024) prints at up to 6.83 × 6.83 in at 150 DPI. It needs 2× to cover A5 (148 × 210 mm), which is free.
- A 1920 × 1080 screenshot or video frame (1,920 × 1,080) prints at up to 7.2 × 12.8 in at 150 DPI: enough for A5 (148 × 210 mm) without upscaling.

How to prepare the file
- Crop your image to the 5.83 × 8.27 shape so the lab does not cut anything off.
- Compare your pixels with 874 × 1,240. The calculator above does it for you.
- Upscale with the smallest scale that reaches the size, then resize to the exact pixels.
- Export PNG, or JPG at quality 95, and order the print at this size.
Questions
How many pixels do I need for an A5 (148 × 210 mm) print at 150 DPI?
874 × 1,240 pixels: 5.83 × 8.27 inches multiplied by 150 dots per inch, rounded to whole pixels.
Is 150 DPI good enough for A5 (148 × 210 mm)?
150 DPI is the usual floor for posters viewed from one to two metres away.
Can a phone photo be printed at A5 (148 × 210 mm)?
Yes. A 12 MP photo of 4032 × 3024 already has more than 874 × 1,240 pixels once cropped to the print shape.
What does DPI mean for a digital file?
Dots per inch is how many image pixels land on each inch of paper. The pixel count is what matters: the DPI field saved in a file does not change the image, the printer scales the pixels to the paper size.
Does upscaling add real detail for printing?
It adds plausible detail: sharper edges and texture instead of the soft blur of ordinary resizing. It cannot recover detail the camera never captured, such as text too small to read.
