I have mine on as I type. I tried them on at my local quilt shop because I wanted them to fit snug not sloppy. On my package it says XS so I guess that means extra small? I have medium length fingernails..1/8 inch passsed fingertip? Measuring from the palm side of my hand is 7 in.? or just the middle finger from web to fingernail tip 3 1/4. Don't know if this will help but I LOVE my machingers!
