IIRC it’s quite long, alomst large XC bike long, 23″+ top tube.
Maybe look at something like a dialled holeshot (short), which is IIRC 21.5″? I built one up for my missus as she’s not much taller than a 12 yr old, it looks like it fits her quite well.
Either way they all carry a 2-3lb penalty over even the cheep XC frames. Brand-X, handsome dog, arrow, dirty-jo all used to do a generic ‘tripple butted’ XC frame which would weigh significantly less if you can find a small enough one.
My/her holeshot is about 30lb using a 1x8speed XT and XC spare bits from the shed (i.e. nothing overly strong, but no expensive/modern light bits).
