Larger concrete pavers generally are from the size 400mmx400mm and up to 600mmx600mm with various sizes in between.
Larger format concrete pavers are made with concrete with various colours of oxides to give a greater colour range.
Being larger in size, when laid they give more of a spacious feel (not so busy compared to the smaller sizes) which suits areas such as patios,verandahs etc.
Not generally used for driveways but if ordered thicker can be used.
