Well, here's a very rough look at some of the weights involved.
This chart assumes a piece of fabric approx .75" larger on all 4 sides, double folded and hemmed. It also assumes 3" channels on each end. It is just the hammock body fabric only.
Overhead = suspension, straps, guylines, net, overcover, zipper, stuff sack, etc.
For Dream Hammock products -
Based on these weights and looking back through historical DB weights, I can say the "overhead" weight on a 10ft long DB is roughly 15.5oz and an 11ft long DB is roughly 17oz. They all vary a little bit due to different little customizations, but you should be able to use these as rough starting numbers.
For DIY and other products -
Info like this could theoretically be used to compare the weights of different combinations of fabrics and help a hanger decide the best amount of fabric to hang on.
This chart does not take into account any coatings or anything that might add a little weight of the fabric.
I hope this helps a little.
