Mismatched dimensions and object display

Any reason I would be seeing this? Same dimension, measured off of two objects. Dimensions are the same, but the objects don’t appear to be the same dimension.

Is this just a rendering discrepancy based on scale/zoom/resolution/etc.? Which should I trust?

That’s pretty small. You could have your dimensions set to the nearest half inch. Check you tolerances in Model Info / Units.

Bingo, that was it. I had the precision set incorrectly. Thanks!
