Accessible curb cuts transition from the low side of a curb to the high side (usually 15 cm or 5.9 in change in level). Accessible curb ramps are a minimum of 1 metre (3.28 ft) wide. They are sloped no greater than 1:12 (8.33%), which means that for every 12 cm (4.7 in) of horizontal distance, they rise no more than one centimetre ( 3 ⁄ 8 in).
