To create thumbnails use the -thumbnail option of convert. This option 
preserves the aspect ratio of the picture. So you need to specify just 
the width or height of your thumbnail.

Sample commands look like

convert -thumbnail 160 original.jpg thumbnail.jpg
convert -thumbnail x160 original.jpg thumbnail.jpg

The first one creates the thumbnail whose width is 160 pixels. The 
second one creates a thumbnail whose height is 160 pixels.
