Will your drink fit Steadi?

Fits drink container bases 2–3.15 inches across. Measure across the flat bottom of your container, not its rim or capacity label.

Check these three things

  1. Base diameter: 2–3.15 inches, including both endpoints.
  2. Clearance: the lower part must seat fully; low handles and extra boots can interfere.
  3. Space: support the holder’s entire 5.2-inch footprint on a level, stable surface.

Check a measurement

Exact-model evidence

The exact 40 oz Stanley Quencher H2.0 has an owner-confirmed snug fit. Other models and sizes need their own measurements. This is not a universal tumbler compatibility claim.
