You just can’t know how tiny a puffin is until you see one… puffins are approximately ten inches full grown. TEN INCHES! And they weigh about a can of coke. How adorable. I wanted you to see just how big (or small) ten inches. This graphic should be exactly ten inches tall. Feel free to get out your rulers! From the top of the black part to the bottom of the black part… these little cartoon puffins are standing head-to-toe just to show you how tall one little puffin is… Puffins are shorter than a piece of paper!!!
