Use 300 DPI as a strong starting point for close-viewed photos and artwork. For large wall prints, 150 DPI can be a practical alternative when the source image does not contain enough real pixels for 300 DPI.
| Print size | Aspect ratio | 150 DPI | 300 DPI |
|---|---|---|---|
| 4 × 6 in | 3:2 | 600 × 900 px | 1,200 × 1,800 px |
| 5 × 7 in | 7:5 | 750 × 1,050 px | 1,500 × 2,100 px |
| 8 × 10 in | 5:4 | 1,200 × 1,500 px | 2,400 × 3,000 px |
| A4 | 1:1.414 | 1,240 × 1,754 px | 2,480 × 3,508 px |
| 11 × 14 in | 14:11 | 1,650 × 2,100 px | 3,300 × 4,200 px |
| 12 × 18 in | 3:2 | 1,800 × 2,700 px | 3,600 × 5,400 px |
| 16 × 20 in | 5:4 | 2,400 × 3,000 px | 4,800 × 6,000 px |
| 18 × 24 in | 4:3 | 2,700 × 3,600 px | 5,400 × 7,200 px |
Resizing changes width and height in pixels, but it should not distort the subject. When the source aspect ratio differs from the print ratio, crop the image intentionally or add borders instead of forcing both dimensions.
| Source shape | Target print | What to expect |
|---|---|---|
| 3:2 camera photo | 4×6, 8×12, 12×18 | No ratio crop needed |
| 3:2 camera photo | 5×7 | Small crop required |
| 3:2 camera photo | 8×10 or 16×20 | More noticeable crop to 5:4 |
| 4:3 phone/camera photo | 6×8 or 9×12 | No ratio crop needed |
| 4:3 phone/camera photo | 18×24 | No ratio crop needed |
| Any rectangular photo | Square print | Crop to 1:1 or add borders |
If your source is larger than the target pixel dimensions on both axes, resizing down is straightforward. If it is slightly smaller, a lower effective DPI may still produce a good print. If it is dramatically smaller, the better options are usually a smaller print or a higher-resolution original rather than aggressive enlargement.
To see the physical print size your current pixels support before changing them, use the Print Size Calculator. For crop behavior across standard photo sizes, see the Photo Print Sizes guide.
target pixels = print size in inches × DPI. Unlike YesDPI tools that only read or edit DPI metadata, this resizer changes the actual pixel grid by resampling the image in your browser.
Downscaling a large source to a smaller target is generally safe. Upscaling can make a file meet a numeric pixel requirement, but it cannot restore texture, focus, or fine detail that was missing from the original. Check the source first with the DPI Checker if you are unsure.
No. Resizing changes the pixel grid to match a target size. Enlarging beyond the original dimensions creates new interpolated pixels but cannot recreate detail that the source image never captured.
Usually yes when the source image and target print use different aspect ratios. For example, a 3:2 camera image does not naturally fit an 8×10 print, which is 5:4. Crop intentionally before or during preparation instead of stretching the image.
An 8×10 inch print at 300 DPI needs 2400 × 3000 pixels. At 150 DPI it needs 1200 × 1500 pixels.
JPG is a practical default for photos. PNG is lossless and supports transparency but is usually much larger for photographic content. Match the format to your print provider's accepted file types when possible.
Yes. Downscaling removes pixels and is generally much safer than enlarging. Keep the original file so you can always return to the highest-resolution source for a larger print later.
