First, my face measures about a foot from ear to ear above the nose. First I have to stretch them to fit, but they hold their new length well. You can probably get away with 13.5 inches before it gets too small. I added some self-adhesive nose strips (like dust masks) into the top hem. Two glued together provide enough strength to hold the shape in my case even though I bought cheap ones. Color variety is quite good as they are two tone and double sided.
