All the boy heads will vary slightly in size, but they all fit in a 4 x 4 hoop, even within one of the quotes. The largest size head is width- 2.50" x height- 1.95", while the smallest is width- 1.85" x height- 1.68". Exact size of all the heads is in the directions file. Comes with 12 heads & 5 quotes. Nine of them also come with glasses for a total of 21 heads. The names that are in the photos are NOT in the design. It is only there to help you identify each head correctly with the directions. These are great for making a family tree - just match the hair color to the child. Perfect for t-shirts, collars, pockets, placmate, etc. These are so fun & quick to do!
