Size images for metric print projects
Convert centimeters and DPI into the pixels needed for photos, documents, and printed materials.
01
Convert centimeters into pixel dimensions
Enter the physical width and height, then choose a DPI. The tool calculates the pixel canvas required to produce that size when printed.
Set width and height in familiar metric measurements
Choose the DPI requested by the printer or service
Review the calculated pixel output before resizing

02
Prepare photos for metric frames
Match family photos, portraits, and artwork to frame or lab sizes stated in centimeters while preserving enough resolution for a clear print.
Create common 10 × 15 cm and 13 × 18 cm prints
Match the crop to the chosen frame proportions
Check faces and fine detail at the final resolution

Centimeter resizing questions
Answers about centimeter dimensions, DPI, pixels, proportions, quality, and print preparation.
How are centimeters converted into pixels?
The tool divides each centimeter measurement by 2.54 to convert it to inches, then multiplies that value by the selected DPI. The resulting pixel width and height are rounded to whole pixels for image output.
Which DPI should I use with centimeter dimensions?
Use the DPI required by the printer, photo lab, or document specification. A 300 DPI target is common for detailed prints viewed closely, while larger displays may use a lower value when their provider allows it.
How many pixels are needed for a 10 × 15 cm photo?
At 300 DPI, a 10 × 15 cm image is approximately 1181 × 1772 pixels after conversion and rounding. The exact orientation depends on whether the photo is landscape or portrait, but the pixel count is the same.
Can I keep the original image proportions?
Yes. Keep Aspect Ratio locked and change one physical dimension; the other follows the source proportions. If a printer requires an exact width and height with a different shape, choose cropping or padding instead.
Will changing centimeters alter the image quality?
Quality depends on the pixel dimensions calculated from size and DPI compared with the source resolution. Reducing usually stays clear, while enlarging a small source can soften texture because genuine detail cannot be recreated.
Can I use centimeter sizing for documents and flyers?
Yes. Enter the physical image area used by the layout and select a DPI suitable for printed text or graphics. Confirm whether the printer expects bleed, because bleed must be included in the dimensions before resizing.
Does changing DPI change the physical size?
The entered centimeter size remains your target, while DPI changes how many pixels are created for each printed inch. Higher DPI therefore increases pixel dimensions and file detail requirements without changing the stated size.
Which image formats can I resize in centimeters?
You can open JPG, PNG, or WebP images and keep the original format or choose another supported output. Use JPG for most photos, PNG for sharp graphics or transparency, and WebP for compact digital copies.
Resize to the centimeters you need
Set the physical size and DPI, review the pixel output, and prepare the image for print.
