Will your coffee cup fit Steadi?
Check the lower cup and handle together.
Measure the base
The supported diameter is 2–3.15 inches inclusive. Cup capacity and rim diameter are different measurements.
Check handle clearance
A handle must clear the fins while the cup seats fully. Do not force a low-handled mug into a partial position.
Check added sleeves
A sleeve or boot changes the lower shape. Measure the actual configuration and do not assume the bare cup’s measurement applies.
