Determining the length of sideburns should be based on two things: face shape and personality. Sideburn lengths can range anywhere from short (top of the ear), extra-long (bottom of the ear), to mutton chops, and anywhere in between. If the look is more conservative the width of sideburns shouldn't exceed 1 ½", Wider (greater that 1 ½") sideburns assume a more creative look in style - and most likely - career choice. The face shape is another factor to consider. The longer the face the shorter the sideburns should be. Consequently, the shorter the face the longer the sideburns can go (within reason). Medium length sideburns (just above the center of the ear) and penciled (or pointed) styles are among the most common and popular. Mutton chops can be found in smaller, more creative circles. But, personality is always a factor as to what look works best.
