Notes
- Car cup holders are not standardized. The figures here are ranges and sizes that products publish so they fit most holders; none is a holder size.
- Custom Accessories' expandable jumbo cup holder has a base that expands from 2.6 to 3.7 in (66.0–94.0 mm) to fit vehicle cup holders.
- Stanley's 40 oz Quencher H2.0 is 2.95 in (75 mm) at the base (REI listing), the size that made it fit most car cup holders.
- No holder geometry is drawn. For an insert or adapter, measure the top and bottom diameters and the depth of your holder, or wait for a scan.
