24" is measured from the top of the ring to the bottom knot with NO pot in the hanger. The tassel below the bottom knot is an additional 4" - 6", depending on the hanger. Your pot will shorten the length of the hanger by a few inches, depending on the size of the pot. An 8" pot will shorten the hanger by about 5".
This Plant hanger is made with 4mm polyolefin cord. It is colorfast, washable and formulated with UV Stabilizers. It is rated for indoor and outdoor use.
This hanger will hold a pot measuring up to 9" wide with a height of 7" and a base of 6". If you want to use a wider pot, it will need to be shorter. Please contact me if you want to know if your pot will fit. Just let me know the width at the top, the width at the bottom and the height of your pot.
