How to Resize an Image in Photoshop

 

 

Images from the camera are rarely the correct size for your projects. Resizing an image allows you to change the dimensions, resolution or both.

 

Step One

With an image open, choose Image > Image Size.

Step Two

In the Pixel Dimensions section you can resize based on pixel size or a percentage of the original image.

Step Three

In the Document Size area you can change to overall Image Size and Resolution.

Step Four

To keep from distorting the image, make sure that Constrain Proportions is checked.

Step Five

If you are enlarging your image, use Bicubic Smoother.

Step Six

Bicubic Sharper works better with image reductions.

Maintaining the Resolution

If you can resize the image by changing the resolution and retaining the same pixel dimensions, there is no re-sampling. Resolution is generally set in Pixels Per Inch (ppi).

Pixel Facts

Web images are usually 72 ppi and print images are 300 ppi. Images are defined as a series of little colored squares called pixels. To see your image on a pixel level, zoom in real close.
