How does one begin to make such a chart? The chart on this page is purely for a mathematical overview. There are a number of factors to consider including subject matter, exposure, focus, and post processing.

I've made great looking 16x20 inkjet prints from my 6MP Nikon D70 but the same image didn't quite cut it for a full page magazine ad. For one, making an inkjet print is different than producing a print ad where you need 300ppi for a 150 line screen. A larger 6MP sensor will of course produce better images than a smaller 6MP sensor of the same type. Randy, I totally agree but I'll have to make a different chart on a new page. And perfect 20x30"s from the full-frame 4mp Canon 1D.

I have 20x30" prints on Fuji Crystal Archive hanging on my wall that turned out wonderful from an 8mp APS-C sized sensor (Canon 350D). The 300dpi mark is indeed "true photo quality" in print terms, but it isn't always needed to get good prints. And also the work done in post has more to do with achievable print size than megapixels.
"The critical part that is being left out which needs to be tied into this information is sensor size. This chart is only about the math and does not take into consideration the subject matter of the image, the media it will be printed on, the amount of post editing that will be done to it, or the viewing distance of the final output. Strictly speaking in terms of pixels per inch, with no post editing, an 8x10 300ppi is (8x300) x (10x300), or 7,200,000 pixels (7MP). "When you go from 8x10 to 16x20 aren't you quadrupling the area? Therefore it would make sense that you would need 24 to 30 megapixels for a 16x20 if you could produce a 8x10 with 6 to 8 megapixels because 6x4=24 and 8x4=32. "Thanks for bringing some light into the megapixel mistery! " Nice chart, one of many reasons why I opted for the 7 megapixel camera over the 5! " I haven't tried anything larger than a 8x10. Even though 7 is not on the chart it is not difficult to see where it would fit. "Nice guide, I got a 7 Megapixel Camera and it makes beautiful 8x10s. Recognize the importance of sensor quality, optics, compression, post processing, and viewing distance. Once again, I made this chart as a visual representation of megapixels. Since people keep making the same comments, I thought it best to have my original answers at the top. Oldest comments at the top because I tried to answer many of the initial comments about this chart. On this page however, I decided to show the On most Design215 pages you'll see the newest comments at the top. "dots per inch" and why you need 300ppi for true **At 150ppi, printed images will have visible pixels and details will look "fuzzy".įor an explanation of "pixels per inch" vs. Actual pixel dimensions vary from camera to camera. If an image is enlarged too much in this manner, it will look Quality of the camera and lense becomes more important at this point bacause any loss of detail or

If you know how to use image editing software like Photoshop, you can "cheat" even moreīy increasing the image size, and even doubling the number of pixels in the image.At 200ppi, the maximum print size becomes: Prints for yourself or your friends, you can "cheat". If you are not publishing your images in a book or magazine, and you're just making.To find the largest photo quality image you can print, simply divide each.If you multiply 3266 by 2450, you get 8,001,700 or 8 million pixels. A typical 8 megapixel camera produces images that are 3266 x 2450* pixels.It's an area measurement like square feet. While you certainly can make a print that Don't be fooled by manufacturers' claims that say youĬan make 16" x 20" prints from an 8 megapixel camera. Print, you need between 24 and 30 megapixels. Make nice 8" x 10" prints with a 6 or 8 megapixel camera, but to make a true photo quality 16" x 20" Notice that as the print size doubles, the megapixels required increases geometrically. Inches 300ppi (numbers inside colored boxes are megapixels) Shows that you can make a 5" x 7" photo quality print from a 3 megapixel camera. Most books and magazines require 300ppi for photo quality.
The top and left side are print dimensions in inches at 300ppi Each colored box represents a certain number of megapixels.
