At screen resolution (72dpi), that file would print at 60.11 x 77.68 cm. In Photoshop, go to image / image size and enter 300 into the resolution box (making sure it's pixels/inch mode selected). Ensure resampling is not checked. this will give a more modest image size of 14.43 x 18.64 cm.

You don't have to resize your image. Just print that image.The printer will take care of pixels-to-dpi.

DPI = Dots Per Inch = how many dots per one inch of paper your printer is printing.

so...if you consider pixel = dot :

1704pixels/300 dpi = 5.68 inch
2272pixels/300dpi = 7.57 inch

so you can print up to 5x7" paper size format.

Note:
- your image is in pixels not in Dots (DPI) ! that so the results of pixels-to-dpi is a slightly different on the paper... pixels are not perfect small circle.They have an eliptical shape = different size for width and height.

You don't have to resize your image. Just print that image.The printer will take care of pixels-to-dpi.

Maybe you want to crop or add pixels to reach a specific ratio between width and height like to perfectly fit a specific paper size (4x6", 5x7" or 8x10").

1704/2272=0.75 know as 4:3 format = perfect good for TV
4/6=0.67 know as 3:2 format = photo paper format
5/7=0.71
8/10=0.81

now, when you know the final size of your photo paper you can resize your picture to fit the paper adding pixels or cropping the image.

Answer 4

you don't DPI means Dots Per Inch and represents the quality of an image as opposed to it's dimensions. You could always RIGHT CLICK the image, then SELECT PROPERTIES and hit the SUMMARY tab, and windows may convert it for you.

DPI will have an impact on the dimensions of an image. For example, if the DPI is set to 72, the images tend to be smaller (and aimed at the Intenret anyway), if the DPI is set to 300, then these tend to be larger and aimed at PRINTED media...

Answer 5

Just try different resolutions saving them as image01 image02 etc.That way you can keep the original and find what you are looking for.
