Every grave is marked with a headstone . Each headstone contains the national emblem or regimental badge , rank , name , unit , date of death and age of each casualty inscribed above an appropriate religious symbol and a more personal dedication chosen by relatives . The headstones use a standard upper case lettering designed by MacDonald Gill . Individual graves are arranged , where possible , in straight rows and marked by uniform headstones , the vast majority of which are made of Portland stone . The original headstone dimensions were 76 centimetres ( 30 in ) tall , 38 cm ( 15 in ) wide , and 7 @.@ 6 cm ( 3 @.@ 0 in ) thick .
