I’ve added just four designs for children roughly between the age of 7 to 14 years old. The facemask measurement is in the description box. I would think from the age of 15 years the adult size would be a better fit. 
Our Face masks are handmade from 100% cotton, which has been pre-washed before cutting the fabric, they have two layers with a filter pocket (1968accessories does not supply or sale filters) the ties are of the same cotton to fasten around the top and neck of your head. The internal nose bridge is made from washable plastic aluminium.
As our Face masks are reusable, to help with keeping them clean before wearing or once worn, pop them into a bag, we have wash bags. These are 100% polycotton double layer with a draw tie of the same fabric. They are in single block colours, so easy to see inside your bag and in the washing machine.

Please be aware that these masks are non-medical grade.

The following advice given here has been gather from the UK Government and WHO (World Health Organisation).   

Remember wearing of a mask only offers a minimal barrier, does not protect you from other people, but could help in protecting other people from you.

You must at all times adhere to the main Government guidelines on how to protect yourself which at the moment is keep a two-metre social distance, try not touching your face and wash/sanitiser hands as often as possible.  Stay safe.
