Uniform Width - GCSE Maths Definition

In GCSE Mathematics, uniform width refers to any two-dimensional, or three-dimensional shape with a width that is constant throughout the length (or height, or depth) of the shape.

• In two-dimensions, shapes such as squares, rectangles and parallelograms have uniform width (between opposite sides)

• In three-dimensions, cubes and cuboids have uniform width, a triangular prism would have uniform height or length - the words width, height and length (and depth) are interchangeable, depending on the exact nature of the shape being considered

Understanding and recognising uniform width means we can quickly identify properties of shapes and this can help solve problems with side lengths, angles, area and volume.
