Just a hair shy of 3 1/4". Most makos that are in this size range are usually not in the best condition. This one is complete with only a tiny nick where the root meets the crown. The enamel has nice color patterns on the display side. This beast is as wide as most makos are long. The largest mako that I have ever had. The tooth pictured with it is dwarfed in size and it's nearly two inches!
