We work with non-designers every day who have questions on how to resize images for Photoshop and how to choose proper dimensions and specs for an optimal outcome. In the interest of saving you back-and-forth time with your own Creative team, here are step-by-step instructions (and some tips and tricks) on how to resize an image in Photoshop and how to choose the right specs.
1. Make a new file in Photoshop
2. Choose a canvas size for your creative
-g. 600×600, 180×180, 300×400, etc.
-Make sure the units are in pixels
3. Evaluate the orientation of your canvas size and choose your image accordingly
The rule of thumb is to have the image go with the same orientation (e.g. landscape, portrait, square) as your canvas – or to go with images with healthy enough margins so that they can be cropped to accommodate several orientations.
-Make sure the image size is greater than the canvas, or you’ll be subject to having your image cropped for downsizing.
-Larger sizes ensure the resolution and clarity of the image.
-DO NOT USE A SMALLER SIZED IMAGE AND ENLARGE IT.
4. Add in the image
-File> place embedded
-Drag out a corner of image (while holding the Shift key, which ensures correct proportions) so it fills the canvas
-Hit Enter or click the check mark to set
-Press “v” to move the image around
-The edge of the image can also snap/align to the edge like in PowerPoint
-Press “Ctrl + t” to resize the image again
5. Save File
-File > save for web
-Choose jpg, png, or gif
-Quality corresponds to file size (higher quality = bigger file size and vice versa)
