The children’s necklaces I have made, for say 5-10 yr. olds, range
from 13" to 14"
I figure a 14" in a tight/choker type on an average adult. So, the
14" would be a drop probably equal to a 17" in an adult.
I use 14" for the older kids…as they have grown and necks are
larger. But, sometimes it is easier to really have the kid measured,
if you are making up a commission.
I am in the process of waiting for a measurement for a pearl and
sterling bead necklace for a 9yr. old.
When they give me the measurement, I will pass it along. But, from
making clothes and costumes for kids, the 12-14" range is pretty safe.
And as Marlo said, if you can make them smaller with extra chain or
jump rings to adjust, they will be able to wear them longer.
What type of necklaces are you making?
