My understanding is that indels are from 1bp to 10Kb, and a healthy genome has ~400K-500K Indels. Surely most of these are small. What is the distribution of insertion sizes in a healthy human genome? What is the distribution of deletion sizes? What is an average ratio of insertions:deletions? I have not found a definitive reference.
What is the distribution of indel sizes in a healthy human genome? of insertion:deletion ratios?

One of the 2015 papers from the 1000 genomes project has a nice figure (figure 1) showing the size distribution of medium to large sized insertions and deletions:From another 2015 1000 genomes paper, one can see that the absolute number of smaller indels is much larger, though an exact size range isn't given (as far as I saw). If you really want to know that, just download the most recent 1000 genomes VCF file(s) and compute the exact median size and/or distribution that you want.
