Hi, the sleeves are pretty normal in length. I'm 5' 4" with longish arms. I always like to order Sarafin sweaters a size up so the sweater fits more loosely. This means I give the sleeves a 1" roll up. If I'd ordered my regular size...pretty sure the sleeves would have fit fine, or a little long. I find that the sleeves do not run short for me - even on my other Sarafins.
Not sure the length, but I'm 5'8" and they were just fine for me.
