LinkedIn personal profiles obtain 21 times more views by adding a professional head shot photo. The preferred LinkedIn profile photo size is 400 x 400 pixels, although it is okay to use an image as big as 7680 width x 4320 height pixels. Use JPG, GIF or PNG format with a maximum file size of 8MB. The video below illustrates how to take a great profile photo. You can either do it yourself with the camera on your phone or there is likely a photographer on Craig’s List in your area that will come to your location for under a $100.
