A thinner bridge creates deeper and more vibrant sounds than those too thick. However, there are no standard measures that can define a particular thickness as an ideal one. The foot thickness of the bridge should be between 4mm to 5mm. Likewise, it should be 1/16 inch thick at the top. Besides thickness, you should also consider the violin bridge angle. The bridge’s back should be at a 90-degree angle to the top of your violin.
