Huh, honestly, the weight shouldn't even be in the Height Parameter. Don't think we have one because it's such an obscure statistic that nearly no character will even have one officially stated..

That said, looking through the history, it looks like someone added 170 cm for height. Later someone changed it to 172, and also added 59kg for weight, but there wasn't a weight parameter, so they just put it together with the Height

But like I said, the information isn't likely to pop up for a lot of characters anyways. Not only that, the only source for the information is from a Q&A the author had in 2005, when SAO was a web-novel.

The Published version has a lot of changes, and some of them are even about the character's traits, like Suguha's breasts recieved a large upscale in the published version, while Rika (Lisbeth) had the opposite. Height and weight is probably also changed. (though for now, keeping it isn't too bad until we get an updated version.)
