The reason I mentioned it, is that I`ve done comparisons before myself. Measuring size, thickness, and most importantly...... weight! Many towels will come with the specification, but as you know... all too many give you nothing, zip, nada, bumpkiss. It`s fairly easy however to measure the overall size, the calculate the GSM. Two VERY popular towels here in the US, both edgeless Korean split weave, one typically in orange, the other in gray (at least initially) are both said to be either 470 GSM or 500 GSM. (
I believe both sellers make them in more than one color now.) The first one (the gray one) actually used to be a lighter weight towel, have a couple from that era.

Now however, (for a couple years now) it`s still sold on the site as a 470 GSM, but in my experience it is both thicker and plusher (is that a word).

The real kicker however is that it is EASILY well over a 500 GSM towel (513 last time I measured).
This is also a stat that would be interesting to add to the spreadsheet(s). Knowing that sellers will represent towels as something that they may indeed have quite a time living up to. (
Good or bad.) I`ve in fact mentioned to Ian and Dan (a
nd the woman that sometimes answers the phone, who`s name I can`t recall right now) on more than one occasion, that they should update their site to reflect that the "Korean 470 edgeless" is (
at a bare minimum) a 500 GSM towel. Then of course there is the orange one from the other guys, and THAT one is known to not actually be as heavy as they first said it was,
go figure. They`ve since updated their website to show a lighter weight (
last time I looked).
So yeah... that`s why I said something in the first place about the true absorption rate, per square mm, cm, decameter, meter, inch, foot, whatever. BEeeeeeCAUSE........ once we weigh, and calculate to know the REAL GSM of each towel, we also can know/calculate the weight of absorption per square `thing-a-ma-jig`. :inspector:
