What do (S), (M), and (L) mean in Illumina library prep kit names?

A few Illumina library prep kits have a single letter in parentheses as part of the library prep kit name:
  • Illumina DNA Prep with Enrichment, (S) Tagmentation
  • Illumina DNA Prep, (M) Tagmentation
  • Illumina RNA Prep with Enrichment, (L) Tagmentation
These letters refer to the general size of the resultant library fragment post-tagmentation. S stands for "small," M for "medium," and L for "large" insert sizes.
