How much resolution for 8x10

To reproduce a 4x6 picture you must scan it at dpi to print it out at the same size. If you want to double the size and print it at 8x12, you must double the dpi to dpi. In the end your 8x12 image will be printed at dpi. What matters, and the number that doesn't change, is the pixel count. When the scanner exports the image it may convert it to 72dpi - doing so did not degrade it because now the image size is greater. Calculating Pixels Ok - finally the mathematical explanation on how all the terms relate to each other.

Lets stick with the same samples numbers I used above. What print size is the optimum resolution. Well, just divide the pixels you have by dpi. You can change the inches and dpi and keep same resolution in pixels. See a different image size can still be the same photo size in pixels and in file size. Some programs let you change image detail like size, dpi, and pixels.

When you do change the inches or dpi, the numbers usually adjust to keep the same pixel value, but you can force the image and overwrite the other two values - doing so can damage your quality. You can trick a printer by forcing or adding more pixels called up scaling , but the image will still print as if it was a low resolution image.

You can't change a x pixel image to x and expect a great 8x10 print. How big is the image displayed on my screen. Well divide the pixels by the screen resolution. What resolution would I get if I scanned a 4x6 print at dpi vs dpi. So you would get a x image. At dpi you would get double. This give you a printed photo double the size. So you would get an 8x12 photo. Since your doubling the scan dpi it's easier to just double the pixels to get the same results.

Now if you were to scan a negative to make a 4x6 print your scan resolution will need to be calculated by pixels needed divided by the actual size of negative. For printing an 8x12 photo you will need an 8. Quality depends on Pixels Everyone thinks having more pixels is better - wrong! Well, up to a certain point. Oversizing is a waste of time and space. You just end up working with a super large file size which takes longer to open and uses up more hard drive space.

You will never get more detail when printing because there is a maximum limit for quality. If you are printing an 8x10, all you need is pixels which gives you about a 6mb file size. The number of pixels will determine the ideal and maximum size you can print. This page provides a guide to the resolution requirements for the most common print sizes.
