This preset sets the output size to 18 × 24 in, which is 18 × 24 in (45.72 × 60.96 cm). It is a physical size, so the number of pixels depends on the DPI: 1728 × 2304 px at 96 DPI, or 5400 × 7200 px at 300 DPI.
There is no widely used named standard at exactly this size, so the preset is useful when a printer, frame or form specifies it directly. Always check the dimensions given by whoever will print or receive the image.

18 × 24 in in pixels
Pixels = size in inches × DPI. DPI is a printing instruction, not a quality setting: it says how many pixels are spread over each inch of paper. With the DPI field on Auto, ResizeAny converts at 96 DPI, which suits screens. For print, set 300 DPI. JPG and PNG output stores the DPI value in the file.
| DPI | Use | Pixel size |
|---|---|---|
| 72 | Screen preview | 1296 × 1728 |
| 96 | Tool default (Auto) | 1728 × 2304 |
| 150 | Large posters, viewed from a distance | 2700 × 3600 |
| 300 | Photos, cards, anything held close | 5400 × 7200 |
Will your photo be sharp enough?
A 12-megapixel phone photo (4000 × 3000) is short of the 5400 × 7200 pixels this size needs at 300 DPI. It would have to be enlarged by about 80%, which looks soft. Use a 150 DPI target (2700 × 3600 px) for a more realistic result, or start with a larger original.
Needed source resolution: 38.9 megapixels or more at 300 DPI.
Matching the 3:4 shape
The output is 3:4. If your photo has another shape, it has to be cropped or it will be stretched. This is how much of each common photo is lost when cropped to fill 3:4:
| Starting photo | Cropped away to fill the shape |
|---|---|
| Phone photo (4000 × 3000, 4:3) | About 44% of the image |
| DSLR photo (6000 × 4000, 3:2) | About 50% of the image |
| Video frame (1920 × 1080, 16:9) | About 58% of the image |
| Portrait phone photo (3000 × 4000, 3:4) | Nothing: same shape |
