# How to determine the appropriate kit configuration to use based on the data needed?

To determine the number of reads needed for the run (project), multiply the desired reads per sample by the number of samples in the pool. With the total number of reads, identify the kit and sequencer that fits the data needs using the sequencer specifications pages, listed below.
