Will your drink fit?
Steadi grips the lower part of your drink. Check the base diameter and any handle close to the base.
The regular range: 2–3 inches
A snug fit is possible up to 3.15 inches. Under 2 inches can be too loose; over 3.15 inches is outside the stated range. A 3-inch sticky note is useful for a first check, but doesn’t show the minimum or handle clearance.
Compatible examples
Standard 12 oz cans fit. Steadi’s founder has also confirmed 7.5 oz mini cans and the exact 40 oz Stanley Quencher H2.0. This is not a claim that every tumbler or every 40 oz container fits.
What about handles?
A low handle may land where a fin needs to grip. A high handle on one compatible tumbler does not establish clearance for other mugs.
Fit is separate from performance. See the real inflatable-mat footage for the setup and conditions shown.
