Raster Image Resolution (DPI)

DPI stands for "dots per inch." It measures the quality of an image when printed. The higher the DPI, the clearer the image will look in print. For our print magazines, all images uploaded to ARC need to be sized at 300 DPI to look sharp and professional.

How to Verify Image Sizing at 300DPI:

1. Find editorial photo dimensions listed in the 2025 Layout Guide_v1.pdf for your specific layout.
2. Check the size of your image. It is commonly listed in pixels. You can find this in image properties or photo-editing software. You'll see something like "3000px x 2400px."
3. Divide the image size by 300 DPI. Example:
   • 3000 pixels / 300 DPI = 10 inches
   • 2400 pixels / 300 DPI = 8 inches
   • Your image at 300 DPI is 10 inches x 8 inches.

Your image must be converted to 300 DPI for this calculation to work. ARC automatically formats all images uploaded to 300 DPI so you can also download the image after you’ve uploaded it to ARC to verify the size.
