Size up
I typically wear a 26 or 27 in jeans, had to size up to a 28 in these. the legs felt fine in the size 27, but the waistband was a bit tight, so i went with the 28s. i am 5'2" 115lbs. i'll also be hemming or possibly just cutting these off, they are about 4 inches longer on me compared to the model pictured.
