When embroidering hats, we are limited by the capabilities of our machinery and the limitations of the structures of specific hats.  We've created this graphic below to show you the maximum embroidery sizes and how big they would look in relation to a standard adult hat or beanie.

There may be some sizing limitations based on the specific products that you end up selecting, so you will need to confirm with your sales representative if you want a large embroidery or a uniqe location.
