Finding the right artificial rocks for your needs if often as easy as simply measuring the object in need of covering and using the charts to decide which rock to use.
The problem most people encounter is when it is time to consult the charts. Because of how each of the artificial rocks are molded, the amount of interior space decreases with height.
So a rock that is 2ft by 3ft wide at the base may only have about 14″ by 18″ of interior space up near the top of the rock.
This can make buying artificial rocks tricky. We always encourage customers to use our free sizing service to play it safe and get it right the first time.
