What is the read length for short-read genome sequencing?

You are here:

We use Illumina MiniSeq for short-read sequencing runs.  The paired-end short read lengths are always 2 x 150bp = 300bp.  Our library prep protocols are designed to fragment DNA into 150bp reads and paired-end reads combine two reads (forward and reverse) into a single 300bp read.

Note that paired-end reads always include an “insert” sequence with a modal distribution peak around 300bp. Effectively, this yields a short-read read length around 600bp.
