A lot of people using digital cameras want to know how large they can blow up or enlarge their photographs based on different pixel settings. This article is aimed at teaching you how much you can enlarge your photographs depending on what type of digital camera you’re using and what the pixel settings are on your camera.

If you require more comprehensive information on photography considering enrolling in our online photography course. The course is comprehensive and interactive. Click here to learn more.

As a general rule of them here is the chart that outlines how big you can blow up your digital pictures.

To use this chart find the resolution of your image and multiply it to find out how many megapixels the image is. For example a 1024 pixel by 1024 pixel image would be a 1MP image because 1024X1024 is about 1 million pixels.

1MP = 1 Million Pixels and so on.

This chart was prepared for us by one of our students.

  Quality Comments Digital Camera dpi Range
Just about the finest quality possible!
200+ dpi
The casual photographer will see no difference to a slight difference when compared to Superb.
150-199 dpi
Better than Good, but not as good as Excellent. The typical photographer will be very happy with prints of this quality.
100-149 dpi
Quality that your typical photographer will be happy with.
80-99 dpi
Quality will depend on the individual picture. For larger size prints the typical photographer will find them acceptable, but the sharpness will not be as high as a Good quality print. Compelling subject matter may trump the loss of sharpness.
79 dpi or less

It should be noted that the image enlargement size recommendations above are on the conservative size and will allow for optimal enlargement capabilities with the best and crispest possible picture.

However, you can still blow your photographs up further if you don’t mind loosing a little bit of crispness.

For example you can enlarge a 6-7 megapixel print to 16.20 or an 8 megapixel print to 17×22. Better yet, you can blow up a 10 megapixel print to 20×30 for a good quality print.
