The width of the boards matters too, not just the length. Since the pressure radiates outward from the clamp (I’ve seen diagrams that show 45ยบ but that’s probably just an approximation), the wider the board, the fewer clamps you need for a given length. For example, picture gluing two 1/4 inch strips. You’ll need a clamp every inch or two, or, better yet, cauls to get even pressure along the joint.

And, I agree with AG, too much pressure will starve the joint. I learned to use just enough to bring the boards together firmly.
