What's the difference between a broadloom metre & a square metre?

A broadloom metre is actually 3.66 square metres, i.e. 1 metre cut from a carpet roll which are normally 3.66 metres in width. It is always a good idea to compare the square metre cost of carpet against other floor coverings such as ceramic tiles or vinyl and timber as they are specifically priced by the square metre and a better comparison of value can be seen.
