Measure your flags

Common sizes for patio slabs are 600 mm and 450 mm.

Make sure the start of your tape measure is flush with the edge of your flags (don't include your grout lines)

Make sure your tape measure is flat and straight

If the edges of your flags are uneven, work with the smallest measurement. 

There are two different options for you to choose from.

SINGLE TILE

MULTI TILE
