I don't think a 140 would be the right size. 140's are for the 100 poundish people, like 100-115. At 70 pounds, she's very light. Something in the 130s would be more appropriate. However this all depends on the models weight specs too. I was riding a 141 at 115 pounds and was right in the weight category for my old board.
^I tend to agree, but 140 is generally were real snowboards start in size...however she is 10 and will likely be growing. When my daughter was about 10, we got her a stiffy option bella 148 (a massive board for her almost as tall as she was and I made 20mm risers so she could get better edge control)...it beat her up the first year, 2nd year she could ride it and 3rd year, at about 105# she was throwin it around and literally straight line bombing groomers at baker.
