End to end it is 6' 7" (or 2m.)
If I put it to the second to last grommet it gives a wrap around circumference of 39" and 40" of leash. If you put it to the VERY last grommet, you would have ample room but your dog would be walking directly beside you.
How tiny are we talking here ladies???? I'm 5'8" weigh about 115 lbs. and I can wear it on the first grommet~ slides down to my hips but stays on.
