Please excuse what is probably an elementary question; however, how can I double the size of a .jpg graphic without getting jaggies? The particular graphic is 2" X 1 1/2" in size, and I would, if possible like to double the print size. I am using PS CS. I attempted to use the resize option and it was a mess. Hopefully someone of you can help me in a manner that this 75 year old will understand. Thanks in advance . . . . . Ed

THe problem us that all resizing, especially resizing up degrades quality. Try using Bicubic Smoother in Image Size.

In Photoshop

Go to the menu bar at the top and select IMAGE then use the drop down palette to select IMAGE SIZE

A dialog box will open.

Make sure that the boxes are checked for Constrain Proportions and Resample Image.

Make sure that Bicubic is selected next to Resample Image. (If it is not, click on the arrows and select it.

In the box for resolution it probably has 72 for pixels/inch. Change that to 144 for an ink jet printer.

At the top, there are two boxes for Pixel Dimensions. Click on the arrows and select PERCENT then type 200 for the Width and Height.

Click OK and you should be ok.

Save the file if you want to print it again or place the enlarged file in another document.

Good luck.

As edjh posted just 5 minutes before you: it better to use Bicubic Smoother for upsizing.

Go to Image/Image Size…

At the bottom of the dialogue, select (i.e., make checks) in both boxes: "constrain proportions" _and_ "resample image"

In the menu next to "resample image", chose "Bicubic" (in order to avoid jaggies).

In Document Size, enter the print resolution (ppi) that you desire (e.g., some number between 150 and 300 ppi); and…

also enter whatever value (probably in inches) that you want for the new, larger print dimension. Just need to enter a value for either the width _or_ the height.

Print
