What is a High-Resolution Image?


How Do I Know if I Have a High-Resolution Image?

Your art needs to be a 300 dpi (dots per inch) high-resolution jpg, tif, or eps file. An eps format is common for logos. You may submit an eps image. Do not submit a png image.

A “dot” (also known as a “pixel”) describes the number of discrete points that can be captured by digital cameras. “Dots per inch” (dpi) measures the density of the image when printed. 72 dpi is an image that has very little ink in a square inch. 300 dpi has a lot of ink in a square inch.

To be included in the product showcase, your image must be at least 2ʺ x 2ʺ (600 pixels x 600 pixels) at 300 dpi. Otherwise, it will “pixilated.” It will look like the enlarged segment in the image below: 

For more information on pixels, dpi, and the importance of using 300 dpi when submitting an image for print publication, see the Image Size Calculator on Tiporama.com

Is my image a 300 dpi jpg?

Look at the digital file of your image. It will have an extension on it that is either jpg, tif, png, or eps.

Example: sample-product-image.jpg

Open your image. Click on “file.” It will give you the image properties. Look under “Details.” 

This image is bigger than 600 pixels x 600 pixels at 300 dpi. Therefore, it is a high-resolution image.

Some images show up as having a lower resolution, like 72 dpi.

For example, your image may have the following properties:

  • Dimensions 1698 x1131
  • Width 1698 pixels
  • Height 1131 pixels
  • Horizontal resolution 72 dpi
  • Vertical resolution 72 dpi

To see if your image is large enough to convert to 300 dpi, go to the Image Size Calculator on Tiporama.com

Plug in the numbers (75 dpi is roughly equivalent to 72 dpi):

Now change the resolution of the output device to 300 dpi 

Yes, your image is bigger than 2ʺ x 2ʺ (600 pixels x 600 pixels) at 300 dpi.
