Arteries range in size both within a person, and within a group of people. The largest artery is the ascending aorta (the biggest vessel that comes out of the heart) measuring 3.5cm in diameter. With the vessels becoming smaller as they are further away from the heart. The smallest vessels (cappilaries) are microscopic and can only be seen under the microscope.

These are tiny blood vessels. Can not tell you exact size. My estimate is for eg arteries in the heart muscle should be around 1/2 mm to 1 mm.

I had an ultrasound of my heart done a few years back. They said the diameter of my aorta arch was 25.4mm (1 inch). Adult male, 6' tall, 180 pounds.

They come in a whole bunch of different sizes, depending on what they are for.
