New Board (not sure what size to choose)

[Lucy]

I'm a beginner snowboarder and I've pretty much only been on it for 3 days. I want my own snowboard though and I'm not sure how big it should be

i'm 5 ft 5.5 inches and weigh 105 lbs. by "beginner" i mean i can make it down without hurting myself (on the bunny slopes XD), going full speed, and i'm probably going to go up to the top of the mountain this winter . but i kind of fail at carving.

i just bought a 142 cm x games snowboard (http://www.costco.com/Browse/Product.aspx?Prodid=11493184&search=snowboard&Mo=7&cm_re=1_en-_-Top_Left_Nav-_-Top_search&lang=en-US&Nr=P_CatalogName:BC&Sp=S&N=5000043&whse=BC&Dx=mode+matchallpartial&Ntk=Text_Search&Dr=P_CatalogName:BC&Ne=4000000&D=snowboard&Ntt=snowboard&No=4&Ntx=mode+matchallpartial&Nty=1&topnav=&s=1) but i'm not sure it'll work so i'm probably going to return it

anyways yea

I have never tried those boards you get at Costco.  They are not a name brand so I wouldn't put too much serious stock in them.  I guess the good thing about Costco is that you can return it any time.

As far as size, somewhere in the 140cm +/- 3 would be fine.  Have you tried the calculator yet?

[Lucy]

yes i have! i couldnt figure out what to put for decimal heights or 145... or whether i was a beginner/intermediate

so i got 143-146

[Frosty]

OK, cool.  Also make sure you get the right WIDTH for you.   That is more important than length.  As for that specific board, I couldn't find the width spec anywhere for it.

Alright I just bought the siren oynx

I want to freestyle too but from the looks of it is seems as if it is a freeride board.

I weighed it and its 10 lbs (probably inaccurate). 144 cm any comments?

[Frosty]

Is it the white one with the ribbon-like swirls on it?

more blue.

[Frosty]

Yeah, that was the one I was thinking of.  There doesnt seem to be much info available on that particular board, so I cannot really say much for it.  Anyone else have on info for this Siren Oynx board?
