Hey Doug,
Thank you very much for your question. The metal book rings are measured from the inside, so the inside to inside dimentions are 3/4 of an inch. The actual ring is 2/10 of a centermeter thick.
Hope that this helps you with your bid and thanks again about your question about the thickness of metal book rings. Please call or e-mail us with any questions.
Thanks!
Miles
