Get Image Dimensions from Command Line
The command line is a gold mine if you come from the perspective of a UI lover. Getting information from the shell instead of opening an app, finding a file or directory, etc...what a novel concept. Opening different image files opens up different apps on my Mac and, as the kids say, "ffs" -- I just want to know the image dimensions.
Using ImageMagick you can find the dimensions of an image from command line:
# Get the size of a JPG
convert photo.jpg -print "Size: %wx%h\n" /dev/null
# Size: 600x872
# Get the size of a PSD
convert website-design.psd -print "Size: %wx%h\n" /dev/null
# Size: 990x1200
You can get the image dimensions of any image type from PNG to JPG to GIF to even PSDs. And the resulting text is as plain as it could be. Dimensions...here you are.

I like to use ImageMagick’s identify command. Easy to remember and gives the size along with some other helpful info:
but that means having ImageMagick installed.

sips!Wow! I always wonder why the command
fileis so unknown on the Mac?No need to install anything! Use
man filefor more information. Works for every kind of files, not just images:
