padding width isn't same as padding height although it is in css file

I’ve changed the size of the thumbnails to be the same as those of my instagram widget. Unfortunately the width of the padding between the pics is smaller than the height although it is the same in the css file:

#pinterest-pinboard-widget-container .row { width: 400px; height: 100px; }
#pinterest-pinboard-widget-container .pinboard { margin-top: 29px; }
#pinterest-pinboard-widget-container .pin_link { padding-top: 5px; }
#pinterest-pinboard-widget-container .pin_text a { color: #999; text-decoration: none; vertical-align: middle; }
#pinterest-pinboard-widget-container .pinboard img { width: 95px; height: 95px; padding: 0 5px 5px 0; }
#pinterest-pinboard-widget-container .pinboard img, #pinterest-pinboard-widget-container .pin_logo img { display: inline; }
#pinterest-pinboard-widget-container a.pin_logo { text-decoration: none; }

any idea?
