Is the spine of this 2-inch ring binder also 2 inches wide?
No. This binder has a 2-inch inner diameter metal ring, while the actual spine width is 3 inches — the spine is wider than the ring.
Why is the spine wider than the ring?
Take the 2-inch binder as an example: The 2-inch ring matches the document thickness it holds. The 3-inch spine fits the full load, preventing warping and document loss, and makes labeling easier for quick content checks and neat organization.
