15.24 × 24.38 cm is a portrait 10:16 format (6 × 9.6 in). To print it sharply, the image needs about 1800 × 2880 pixels, which is 5.2 megapixels.

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.

15.24 × 24.38 cm 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	432 × 691
96	Tool default (Auto)	576 × 921
150	Large posters, viewed from a distance	900 × 1440
300	Photos, cards, anything held close	1800 × 2880

Will your photo be sharp enough?

A 12-megapixel phone photo (4000 × 3000) has more than the 1800 × 2880 pixels this size needs at 300 DPI, so it can be printed sharply with room left to crop.

Needed source resolution: 5.2 megapixels or more at 300 DPI.

Matching the 10:16 shape

The output is 10:16. 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 10:16:

Starting photo	Cropped away to fill the shape
Phone photo (4000 × 3000, 4:3)	About 53% of the image
DSLR photo (6000 × 4000, 3:2)	About 58% of the image
Video frame (1920 × 1080, 16:9)	About 65% of the image
Portrait phone photo (3000 × 4000, 3:4)	About 17% of the image

How to resize an image for ebook cover

Add your image. Select a photo or drag it onto the box above. JPG, PNG, WebP, AVIF, HEIC and BMP files are accepted, and the file stays on your device.
Set the resolution. The preset fills in 15.24 × 24.38 cm. Leave DPI on Auto to convert at 96 DPI, or enter 300 DPI for print so the file has enough pixels for a sharp result.
Crop if the shape differs. The target shape is 10:16. If your photo is a different shape, crop it first so the print is not stretched.
Download and print at 100%. Save as JPG or PNG; the DPI value is stored in the file. Print at 100% scale, not "fit to page", so the physical size stays exact.

Frequently asked questions

What is 15.24 × 24.38 cm in pixels?▼

It depends on DPI: 576 × 921 px at 96 DPI, 900 × 1440 px at 150 DPI and 1800 × 2880 px at 300 DPI.

What DPI should I use for a 15.24 × 24.38 cm print?▼

300 DPI for anything seen up close, such as photos, cards and labels; 150 DPI is acceptable for larger prints viewed from a distance. Higher than 300 rarely gives a visible gain.

What is 15.24 × 24.38 cm in other units?▼

6 × 9.6 in, 15.24 × 24.38 cm and 152.4 × 243.8 mm. It does not correspond to a common named standard.

How do I make sure it prints at exactly 15.24 × 24.38 cm?▼

Set the size and a DPI, download the file, and print at 100% scale. Options such as "fit to page" or "shrink to printable area" silently change the physical size, so turn them off. If a lab does the printing, tell them the exact size rather than relying on the file's DPI value.

Is a phone photo big enough for 15.24 × 24.38 cm?▼

Yes. A 12-megapixel phone photo has more than the 5.2 MP needed at 300 DPI.

Do I need an account, and does it add a watermark?▼

No account and no watermark. Open the page, add your photo, and download the result. Because processing happens on your own device, there is no queue and nothing to wait for, even with a large original.
