Compare grinder pad footprints
Use length, width and height to check fit and storage.
Use both footprint dimensions
INMI lists 9.4 × 4.2 inches. Bedroom Bliss lists 10.1 × 3.5 inches. The second is longer and narrower. Trace each footprint on paper if you want to compare how it will fit in a drawer or on a surface.
Check height and the underside separately
Bedroom Bliss gives an overall height of 5.4 inches and identifies a suction cup. INMI gives separate feature measurements rather than an overall height. Ask for the total height and a photo of the base if those affect your choice.
