The dimensions of a Brompton when folded are 585mm high x 565mm long x 270mm wide (23" x 22.2" x 10.6").
(Measurements are based on a bike with folding pedal and a standard seat pillar and saddle; measurements will vary slightly by model - e.g. opting for a model without mudguards will reduce the height of the folded package.)
Every Brompton has a full-length wheel base of 1045mm (41.2"); pre-2003 models had a slightly shorter wheelbase of 1.02m (40.2").
