THE REFERENCE SHELF
Dimensions & fit
Measure the unfolded pad before the order
Two sides, a selected size, and enough floor space: start with the physical dimensions.
Outer size is not the absorbent area
A border and an absorbent center can occupy different portions of the same rectangle.
A bag size does not establish dispenser fit
The opened bag and its stored roll are different objects with different fit requirements.
A larger rectangle is not an absorption test
Square inches describe area; they do not measure liquid volume or holding time.
Check the holder against the whole pad
A holder needs the dimensions and fastening details of the actual pad.
