I think this came up before but can't recall who was at fault so....
Roughly speaking- Ignoring any cuts:
A 12' long in a rectangle... 12x12= 144 inches. Two panels (sides)= 288 inches
standard width is 54" per panel (8'6" wide) so 288x54= 15,552 sq inches of material
There are 1296 sq in per yard. 15552/1296= 12 yards on the nose.
12 yards x .51 ounces per yard- (12x.51=) 6.12 ounces.
Probably a bit of seam allowance in there on the length but at these fabric weights call it 6.25 ounces and move on.
Neither vendor is silly enough to use heavy webbing in lieu of grosgrain or to apply edge binding so for the most part the notions should be similar in weight.
Reinforcing, seam tapes, adhesives, and whatever... adds up fairly fast when the fabric is so light... but should be in the ballpark of each other too.
Checking the flat rectangle tarps on each site-
Hammock gear- Weight for Green 12' x 8'6" = Approximately 10.02 ounces (284 grams)
Dutchware- Says 283g with panel pulls- if you select the options.
Just for fun- Zpacks 8.5' x 10' flat tarp is
Weight 7.1 oz / 200 g multiply by 1.2 for 12' long and you're at 8.52 ounces.
Still makes sense to me as they are a bit tighter on their grosgrain use/tie out reinforcements and absolute SUL customer base.
Long story short- looks like the Hammock Gear under 6 ounce weight on the site is a typo or busted calculation and Occam's human error once more shaves the day.
